The construction industry in India is one of the largest economic activities and is growing at an average rate of 9. 5% as compared to the global average of 5%. As the sector is growing rapidly, preserving the environment poses a host of challenges. To enable the construction industry to be environmentally sensitive, CII-Sohrabji Godrej Green Business Centre has established the Indian Green Building Council (IGBC). IGBC is a consensus driven not-forprofit council representing the building industry, consisting of more than 500 committed members.The council encourages builders, developers and owners to build green to enhance the economic and environmental perform ance of buildings. The Green Building Movement in India has been spearheaded by IGBC since 2001, by creating national awareness. The council’s activities have enabled a market transformation with regard to Green Building concepts, materials and technologies. IGBC continuously works to provide tools that facilitate the adoption of green building practices in India. The development of IGBC Green Homes Rating System is another important step in this direction. IGBC Membership IGBC draws its strength from its members who have been partners in facilitating the Green Building Movement in India.The local chapters led by individual champions and committed members have been instrumental in reaching out the vision of the IGBC at the regional levels. IGBC is today seen as a leader in spearheading the Indian green building movement. The council is member driven and consensus based.

Introduction The housing sector in India is growing at a rapid pace and contributing immensely to the growth of the economy.This augurs well for the country and now there is an imminent need to introduce green concepts and techniques in this sector, which can aid growth in a sustainable manner. Green concepts and techniques in the residential sector can help address national issues like handling of consumer waste, water efficiency, reduction in fossil fuel use in commuting, energy efficiency and conserving natural resources. Most importantly, these concepts can enhance occupant health, happiness and wellbeing. Against this background, Indian Green Building Council (IGBC) has launched ‘IGBC Green Homes Rating System’ to address the national prioriti es. By applying IGBC Green Homes criteria, homes which are sustainable over the life cycle of the building can be constructed.This rating programme is a tool which enables the designer to apply green concepts and criteria, so as to reduce the environmental impacts, which are measurable. The programme covers methodologies to cover diverse climatic zones and changing lifestyles. IGBC Green Homes is the first rating programme developed in India, exclusively for the residential sector. It is based on accepted energy and environmental principles and strikes a balance between known established practices and emerging concepts. The system is designed to be comprehensive in scope, yet simple in operation. IGBC has set up the Green Homes Core Committee to develop the rating programme. This committee comprised of key stakeholders including architects, developers, home owners, manufacturers, institutions and industry representatives.The committee, with a diverse background and knowledge has enr iched the rating system both in its content and process. 10 II. Benefits of Green Homes Green homes can have tremendous benefits, both tangible and intangible. The most tangible benefits are the reduction in water and energy consumption right from day one of occupancy. The energy savings could range from 20 – 30 % and water savings around 30 – 50%. Intangible benefits of Green homes include enhanced air quality, excellent daylighting, health & wellbeing of the occupants, safety benefits and conservation of scarce national resources. Green Homes rating system can also enhance marketability of a project. III.National Priorities Addressed in the Rating System The Green Homes Rating System addresses the most important National priorities which include water conservation, handling of consumer waste, energy conservation, conservation of resources like wood and lesser dependence on usage of virgin materials. Water Efficiency: Most of the Asian countries are water stressed and in countries like India the water table has reduced drastically over the last decade. Green Homes encourages use of water in a self – sustainable manner through reducing, recycling and reusing strategies. By adopting this rating programme green homes can save potable water to an extent of 30 – 50%.Handling of House -hold Waste: Handling of waste in residential buildings is extremely difficult as most of the waste generated is not segregated at source and has a high probability of going to land fills. This continues to be a challenge to the municipalities which needs to be addressed. IGBC intents to address this by encouraging green homes to segregate the house hold waste. Energy Efficiency: The residential sector is a large consumer of electrical energy. IGBC Green Homes can reduce energy consumption through energy efficient lighting, air conditioning systems, motors, pumps etc. , The rating system encourages green homes which select and use BEE labeled equipment and appliances. The energy savings that can be realised by adopting this rating programme can be to the tune of 20 – 30%.Reduced Use of Fossil Fuels: Fossil fuel is a slowly depleting resource, world over. The use of fossil fuel for transportation has been a major source of pollution. The rating system encourages the use of alternate fuels for transportation and captive power generation. Reduced Dependency on Virgin Materials: The rating system encourages projects to use recycled & reused material and discourages the use of virgin wood thereby addressing environmental impacts associated with extraction and processing of virgin materials. Reduced usage of virgin wood is also encouraged. 11 Health and Well-being of Occupants: Health and well-being of occupants is the most important aspect of Green Homes.IGBC Green Homes Rating System ensures minimum performance of daylighting and ventilation aspects which are critical in a home. The rating system recognises measures to minimise the indoor air pollutants. IV. IGBC Green Homes Rating System IGBC has set up the Green Homes Core Committee to focus on residential sector. The committee includes architects, realtors, experts on building science and industry representatives. The varied experience and professions of the committee members brings in a holistic perspective in the process of developing the rating programme. A. Evolution of the Rating System IGBC, in its endeavor to extend green building concepts to all building types envisioned a rating programme for homes in December 2007.A core committee was formed under the leadership of Ar Sharukh Mistry, Mistry Architects, Bangalore. The committee drafted the pilot version of the programme which was launched in May 2008. The rating system is designed to suit Indian climate and construction practices. About 220 members representing 120 organisations participated in the pilot programme. 52 projects with 41. 5 million sq. ft of building footprint area from various clima tic zones registered under the pilot rating programme. After one year of implementation, feedback from pilot projects were reviewed by the core committee and the suggestions have been incorporated in the final rating system launched in March 2009. The rating system will be subjected to a eview by the core committee, every 6 months, to ensure that it is updated and contemporary. B. Features of IGBC Green Homes IGBC Green Homes Rating System is a voluntary and consensus based programme. The rating system has been developed based on materials and technologies that are presently available. The objective of IGBC Green Homes is to facilitate the creation of energy efficient, water efficient, healthy, comfortable and environmentally friendly houses. The rating system evaluates certain credit points using a prescriptive approach and other credits on a performance based approach. The rating system is evolved so as to be comprehensive and at the same time user-friendly.The programme is fundam entally designed to address national priorities and quality of life for occupants. 12 The rating programme uses well accepted national standards and wherever local or national standards are not available, appropriate international benchmarks have been considered. C. Scope of IGBC Green Homes IGBC Green Homes Rating System is a measurement system designed for rating new residential buildings which broadly include two construction types: 1. Dwellings where interiors are part of the project. 2. Dwellings where interiors are not part of the project *Interiors include but not limited to refrigerators, internal lighting, furniture, carpets, etc.Based on the scope of work, projects can choose any of the above options. The following categories of dwelling can apply for rating: v Individual homes v Gated communities v High rise residential apartments v Existing residential buildings v Residential buildings with major renovation v Hostels, Service apartments, Resorts, Motels and Guest houses In general all dwelling spaces which can meet the mandatory requirements and minimum points can apply. Various levels of green building certification are awarded based on the total points earned. D. The Future of IGBC Green Homes Many new green building materials, equipment and technologies are being introduced in the market.With continuous up-gradation and introduction of new green technologies and products, it is important that the rating programme also keeps pace with current standards and technologies. Therefore, the rating programme will also undergo periodic revisions to incorporate the latest advances and changes. It is important to note that project teams applying for IGBC Green Homes should register their projects with the latest version of the rating system. During the course of implementation, projects have an option to transit to the latest version of the rating system. IGBC will highlight new developments on its website on a continuous basis at www. igbc. in 13 V. IGBC Green Homes Process The guidelines detailed under each credit enable the design and construction of green homes of all sizes and types.IGBC Green Homes addresses green features under the following categories: v Site Selection and Planning v Water Efficiency v v v v Energy Efficiency Materials Indoor Environmental Quality Innovation & Design Process Different levels of green building certification are awarded based on the total credits earned. However, every Green Home should meet certain mandatory requirements, which are non-negotiable. The various levels of rating awarded are: v ‘Certified’ to recognise best practices v ‘Silver’ to recognise outstanding performance v ‘Gold’ to recognise national excellence v ‘Platinum’ to recognise global leadership a. When to use IGBC Green Homes IGBC Green Homes is designed primarily for new residential buildings.However, it is also applicable for existing buildings redesigned in accordance with the IGBC Green Homes criteria. The project team can evaluate all the possible points to apply under the rating system using a suitable checklist. The project can apply for IGBC Green Homes certification if it can meet all mandatory requirements and achieve the minimum required points. b. IGBC Green Homes Registration Project teams interested in IGBC Green Homes Certification for their project must first register with IGBC. Projects can be registered on IGBC website (www. igbc. in) under ‘IGBC Green Homes’. The website includes information on registration fee for IGBC member companies as well as non-members.Registration is the initial step which helps establish contact with IGBC and provides access to the required documents, templates, important communications and other necessary information. Consult the web site for important details about IGBC Green Homes application as well as the certification review process, schedule and fee. 14 c. IGBC Green Homes Certification Le vels The rating system caters to projects like individual houses, apartments, motels, resorts, hostels, etc. , Amongst the different types, projects are broadly classified into two categories: v Projects where interiors are part of scope of work v Projects where interiors are not part of the scope of work Interiors include but not limited to materials like interior finishes & furniture and appliances like refrigerators, fans, lights etc. As a general guideline, individual owners can use the checklist ‘Projects with Interiors’ and developers & builders can use the checklist titled ‘Projects without Interiors’. However, if the context varies, projects can adopt the one which is the closest fit. The threshold criteria for certification levels are as under: Certification Level Certified Silver Gold Platinum Points for projects with interiors 32 – 39 40 – 47 48 – 59 60 – 80 Points for projects without interiors 30 – 36 37 †“ 44 45 – 55 56 – 75 d. Documentation The project team is expected to provide supporting documents at each stage of submission for all the mandatory requirements and the credits attempted.Supporting documents are those which provide specific proof of meeting the required performance level, such as, specifications, drawings (in native format only), cutsheets, manufacturer’s literature, purchase invoices and other documents. These details are mentioned in this guide, under each credit / mandatory requirement. Documentation is submitted in two phases – design submittals and construction submittals: v The design submission involves those credits which can be evaluated at the design stage. The reference guide provides the list of design and construction phase credits. After the design submission, review is done by third party assessors and review comments would be provided within 40 working days. v The next phase involves submission of clarifications to desi gn queries and construction document submittal.The construction document is submitted on completion of the project. This review will also be provided within 40 working days, after which the rating is awarded. 15 It is important to note that the credits earned at the design review are only considered as anticipated and are not awarded until the final construction documents are submitted along with additional documents showing implementation of design features. If there are changes for any design credit anticipated, these changes need to be documented and resubmitted for the construction review phase. IGBC will recognise homes that achieve one of the rating levels with a formal letter of certification and a mountable plaque. e.Precertification Projects by developers can register for Precertification. This is an option provided for projects aspiring to get precertified at the design stage. The documentation submitted for precertification must detail the project design features which wi ll be implemented. The rating awarded under precertification is based on the project’s intention to conform to the requirements of Green Homes Rating system. It is important to note that the precertification rating awarded need not neccesarily correspond to the final certification. Precertified projects are required to provide the status of the project to IGBC, in relation to the rating, once in every six months until the award of the final rating.Precertification gives the owner/developer a unique advantage to market the project to potential buyers. Those projects which seek precertification need to submit the following documentation: †¢ †¢ †¢ †¢ For each credit, a narrative on how the project would meet the goal Design calculations, wherever appropriate Drawings (in native format only) as appropriate Filled in templates wherever applicable IGBC would take 40 working days to review the first set of precertification documents. On receiving the clarificatio ns posed in the first review, IGBC would take another 40 working days to award the precertification. A certificate and a letter are provided to projects on precertification. f.Credit Interpretation Ruling In some instances the design team can face certain challenges in applying or interpreting a mandatory requirement or a credit. It can also happen in cases where the project can opt to achieve the same goal through a different compliance route. To resolve this IGBC uses the process of ‘Credit Interpretation Ruling’ (CIR) to ensure that rulings are consistent and applicable to other projects as well. 16 The following are the steps to be followed in case the project team faces a problem: v Consult the Reference Guide for description of the credit goal, compliance options and calculations. v Review the goal of the credit or mandatory requirement and self-evaluate whether the project satisfies the goal. Review the Credit Interpretation web page for previous CIR on the relev ant credit or mandatory requirement. All projects registered under IGBC Green Homes will have access to this page. v If a similar CIR has not been addressed or does not answer the question sufficiently, submit a credit interpretation request. Only registered projects are eligible to post CIRs. Two CIRs are answered without levying any fee and for any CIR beyond the first two CIRs, a fee is levied. g. Appeal Generally credits get denied due to misinterpretation of the goal. On receipt of the final review, the project team has the option to appeal to IGBC for reassessment of denied credits or mandatory requirements.The documentation for the mandatory requirements or credits seeking appeal may be resubmitted to IGBC along with necessary fee. IGBC will take 40 working days to review such documentation. These submissions would be reviewed by an assessor not involved in the earlier assessments. Documentation for appeals should include the following i. Documentation submitted for design su bmission ii. Documentation submitted for construction submission iii. Clarifications along with necessary drawings and calculations VI. Fee Certification fee details can be found on IGBC website. VII. Updates and Addenda This is the first version of IGBC Green Homes Abridged Reference Guide. As the rating system continues to improve and evolve, updates and addenda to he reference guide will be made available through the website.

Luca Pacioli

Fra Luca Bartolomeo de Pacioli (sometimes Paciolo) (1445–1514 or 1517) was an Italian mathematician and Franciscan friar, collaborator with Leonardo da Vinci, and seminal contributor to the field now known as accounting. He was also called Luca di Borgo after his birthplace, Borgo Santo Sepolcro, Tuscany. Luca Pacioli studied in Venice and Rome and became a Franciscan friar in the 1470s. He was a travelling mathematics tutor until 1497, when he accepted an invitation from Lodovico Sforza (â€Å"Il Moro†) to work in Milan. There he collaborated with, lived with, and taught mathematics to Leonardo da Vinci. In 1499, Pacioli and Leonardo were forced to flee Milan when Louis XII of France seized the city and drove their patron out. After that, Pacioli and Leonardo frequently traveled together. Upon return to his hometown, Pacioli died of old age in 1517. Pacioli published several works on mathematics, including: Summa de arithmetica, geometria, proportioni et proportionalita (Venice 1494), a synthesis of the mathematical knowledge of his time, is also notable for including the first published description of the method of keeping accounts that Venetian merchants used during the Italian Renaissance, known as the double-entry accounting system. Although Pacioli codified rather than invented this system, he is widely regarded as the â€Å"Father of Accounting†. The system he published included most of the accounting cycle as we know it today. He described the use of journals and ledgers, and warned that a person should not go to sleep at night until the debits equalled the credits. His ledger had accounts for assets (including receivables and inventories), liabilities, capital, income, and expenses—the account categories that are reported on an organization's balance sheet and income statement, respectively. He demonstrated year-end closing entries and proposed that a trial balance be used to prove a balanced ledger. Also, his treatise touches on a wide range of related topics from accounting ethics to cost accounting.

Alcoholism and Its Effects on a Family Essay - 1592 Words

Alcoholism and Its Effects on a Family Alcoholism, although thought mostly of its impact on the alcoholic themselves, it is also a very present problem in the ruining of his or her friends and their families lives. Someone who may be a fully functional, great person to his or her family may be extremely dangerous, dishonest, and destructive while they are under the influence of alcohol.

Congruent to the article previously mentione d, Rex Walls demise in the Glass Castle is imposed to of been caused by his excessive drinking during his life. The fact was that, although Dad was only fifty- nine, he had been smoking four packs of cigarettes a day since he was thirteen, and by this time he was also putting away a good two quarts of booze daily. He was, as he had put it many a time, completely pickled.(Walls 278- 279) Considering the circumstances Rex Walls was fortunate that he had lived as long as he did. Although alcohol plays a substantial part in physical and mental destruction, it also has caused Rex and a cornucopia of other alcoholics to be dishonest and break promises. The most essential promise was that he would construct a Glass castle for their family to reside in. His family completely doubted that this task would ever be accomplished beca use he had never amounted to anything he said he would do because of the alcohol.Show MoreRelatedEffects Of Alcoholism On A Family1635 Words   |  7 Pagesâ€Å"Approximately 26.8 million children are exposed to alcoholism in the family and 6.6 million children age 18 and younger live in households with at least one alcoholic parent† (Rachel Lohmann P.H.D.

Human Rights, Obligations, And World Hunger - 1783 Words

Many moral theories have been proposed to understanding our obligations and responding to the perceived injustices present in the world such as world hunger and world poverty, two of the most prominent of these theories are utilitarianism, and human rights. In her essay ‘Rights, Obligations, and World Hunger’, Onora O’Neill critically examines these theories and highlights their inadequacy towards understanding our obligations towards alleviating world poverty, then goes on to propose a third alternative theory to the aforementioned theories, which she believes is better suited. The theory she proposes is that of the Kantian ethical theory developed by 18th century philosopher Immanuel Kant. This theory is indeed the best suited to understanding our obligations to alleviating world poverty. Before expounding on the Kantian theory that O’Neill proposes, and why it is the optimal approach for understanding our obligations to those suffering from world pover ty, I will very briefly summarise the other two moral theories, and explain why O’Neill is correct in her assessment that they are inadequate to dealing with the problem at hand. Utilitarianism is the moral theory which proposes that the best and correct course of action to take is that which will maximize happiness and minimize suffering. In relation to world poverty, it would seem that the most appropriate action to take from a utilitarianism perspective would be something akin to what utilitarian Peter SingerShow MoreRelatedRight to Food Essay560 Words   |  3 PagesRIGHT TO FOOD Right to Food is a human right i.e. access to the adequate food is fundamental right of human.

A Critique of Gone to Soldiers by Marge Piercy Essay Example For Students

A Critique of Gone to Soldiers by Marge Piercy Essay A Critique of Gone to Soldiers by Marge PiercyA Critique of Gone to Soldiers by Marge PiercyThe novel Gone to Soldiers by Marge Piercy intricately weaves the livesof many different people into a connected series of individual plots that givethe reader an exciting view of life during World War II. Piercy connects thelives of women and men, Jews and gentiles by using family ties and steamy loveaffairs. The people have dramatically different profiles, some are rich someare poor, some are Americans, some are French, some are with power while othersare persecuted, but everyone is connected by the war. War freed women byallowing them to work in factories and defy their husbands by hiding resistingFrench Jews. Piercy makes history exciting by making each character reallyexperience love and hate and the mundane daily struggles of the individual. I completely enjoyed Gone to Soldiers, because several main charactersprevented me from getting bored and kept me reading to find out what was goingto happen to each person next. I really enjoyed the profile of Louise Kahan afemale Jewish American writer, because she is independent and strong willed. Anexample of her strength and belief in herself Louise did not instantly return toher ex-husband Oscar even though they both still loved each other, because shewas strong enough to resist him and his womanizing ways. Piercy gave me a muchbetter understanding of the cultural and social issues of the World War two era. I learned about the little struggles of working American women, such as theunavailability of stockings and societys negative attitude towards womenwearing pants. These issues were ones that I had never thought about before. It amazes me that only fifty years ago a woman could not wear pants to work. Ruthies friend was sent home to change for wearing loose fitting red pantsbecause they were considered racy. It is equally surprising to me that womenstill have to wear hose with our skirts or be deemed inappropriate. I do notunderstand how society has completely changed from a white male society into amuch more diverse culture and still expect women to wear uncomfortable hose. Piercy made complete sense throughout the entire book and most importantly shekept my attention. Piercys point of view was biased favorably towards AmericanJews. I enjoyed the book because it kept my attention on the individual livesof people in the midst of war instead of the battles fought during the war. Ialso liked the complicated weave of lives into one story like a patchwork quilt. In conclusion, I enjoyed Marge Piercys novel Gone to Soldiers, becauseit kept my attention with realistic descriptions of people with whom I began toreally understand their feelings and thoughts. Other students should read thisbook if they like historical fiction, because it is so captivating. Piercy usesthe individual as a piece of the whole picture, important but not the entiretyof the work which makes this book so intriguing.

The weakness of agile method Introduction Software development is a complicated process to deliver products in more rapidly, enhanced and cheaper ways. Agile method as a new mythology can fit this goals very well, it can defeat the rapid change in organization and business which the traditional methods is hard to handle. The core of agile methodologies is people. Customer and each team member in agile development teams are the key success or failure factor in agile process. Due to this nature of the agile method, there are several problems may happen in the agile software development process. In this article, several weakness of agile method will be identified and discussed with the examples, and these weaknesses will be divided Into three groups to analysis, they are People, flexibility and structure. For the people group, some problem caused by Active user Involvement and close collaboration are required throughout the placement to ensure the agile development process operate successfully ,however can be a big problem in agile development. For the flexibility group, due to the flexibility of the agile method, the requirement are always changed that will lead to the unwilling to implement the design, ever-lasting project, scope creep. For the structure group, the less detail of the requirement may lead to the misunderstanding which will caused delays in deliverables, the testing is integrated throughout the lifestyle which can caused much more money, the constraint that the team members would in same location can be the disadvantages in agile method. People Active user involvement and close collaboration The core of agile methodologies is people, customer and each team member in agile development teams are the key success or failure factor in agile process.

However, in the real life there are some many reasons will prevent the user to take their time and big commitment to involve in the agile development. From the results of the Dry research of the obstacles in agile software development teams. Not all the Agile teams are made by the experienced team members, the length of the experience are various between each team members. And that will caused lack of commitment to a decision in the agile development process. In some team, nobody was willing to make a decision and resolution was left to the Scrum Master. Because when they face a unfamiliar situation, especially the complex situation, they dont have sufficient expertise to make a right decision, they afraid to make a wrong decision and they dont how to solve this problem correctly. And sometime they are too many decision to choice, its hard for a inexperienced member to decide which one is better. (Dry, 2012) When the agile process coming to the iteration retrospective, one of the member noted The same issues kept coming up iteration after iteration. The problems were not going away. We made a bunch of decisions at the end of the iteration but nobody followed through in the Softies case in the Drugs research. Because less experienced team members naturally have less certainty about their decisions and this can lead to a lack of ownership and accountability for their decisions. Nobody felt they owned the decision, and everyone just focused on delivering the committed content after retrospective, no body followed the decision they made in retrospective. And for the Scrum master in this case, he said, I Just didnt have time to think about it. I felt under pressure to deliver on our user stories and didnt have time to go back and look at what we talked about during the Retrospective. Therefore, the experienced members will also not attention to the agile process under the complex situation (Dry, 2012). The term of agile in scrum refer that owner think, it is difficult for development team to have an holistic view in product and desires status (Sahara, 2012). Agile method is very demanding on the user representatives time and requires a big commitment for the duration of the project. This can be a weakness of agile method. Flexibility One of the biggest benefits of using agile is that the requirement can be accepted and changed any time throughout the development which provides much more flexibility. Requirements changed all the times The flexibility of agile method can ensure the project are delivery the right product, ay be happen if the requirement are never stop and essential, and it may create the risk of ever-lasting project. And in the Largess case study of Drugs research, one of the projects had 22 new user stories, each of which had changed at least twice during the 2 days, it subsequently caused havoc, fear, panic and resentment on these projects within 2 days of it being introduced (Dry, 2012). Agile method can handle changes, but how to handle the problem caused by change is a question. Less predictability Due to the flexibility feature of the agile method, the project can be start with less accessory information because it can be improvement in future iteration. That cause a situation that the developer doesnt know what the project is actually going to deliver to the customer at the start of the project and during. It makes it harder to define a business case for the project, and harder to define how much money will be cost in a particular project. Furthermore, in the iteration of the project development, the lack of design or some long-term view make it easy to take wrong solutions or wrong small scale design that afterward need to be redone. Requirements changed all the times and less predictability can be a weakness in the agile method, without the maturity of a strong and clear understand what the project is going to delivery, and the discipline of fixed timetable and project scope, these two weakness can be dangerous to the project development. Structure Agile software development is a group of software development methods based on iterative and incremental development, where requirements and solutions evolve through collaboration between self-organizing, cross-functional teams. (wisped). According to that definition, we can identify that agile is an incremental placement ,the requirements and solutions will be developed through the team collaboration. In this part, I will talk three potential issues may occur in each features. Misunderstand of the requirement Agile requirements are barely sufficient which mean that the wasted effort on deliverables that dont last in the final product will be eliminates; it will saves time and money. However the requirements are always clarified Just in time for development and can be documented in much less detail due to the timeliness of conversations. Therefore, it is harder for the new starters in team to understand hat they should to do, especially for the team members who are not good at team work and communications and are used to everything being defined up front. Due to that reason the misunderstanding may occur and misunderstanding will expand after several iterations. It may cause the delays in deliverables Agile testing In agile method, testing is integrated throughout the lifestyle of the iteration. This helps to ensure quality of the project and prevent the lengthy and unpredictable test phase at the end of the project. However, testers are needed throughout the project which will increase the cost of the project. Furthermore, several problems may also happen in the testing. For example, it is difficult to keep everyone on the same page. Information changed so fast in agile method, everyone is support to be fully understand the day-to-day-progress, and teams have to find a suitable way to share this information that works for them, this information include who is allocated to what and what development and testing tasks are in progress. Borderland,2012) The core of agile method is people, and the team collaboration is extremely important to the agile development. To ensure a good communication and collaboration environment, it is necessary to have all team members in the same location. The highly collaborative mode required for agile method is not compatible with distributed locations which may cause issue in some contexts to involve the right resources. For example, the time different may cause the necessary resource cannot be delivered on time. How to manage these weaknesses There are some many uncertainties in the agile method, it is hard to prevent all the risk at one time. But there are some advice can be referred to help agile team avoid unnecessary mistake. First for the problem occur in the people group, used some incentives to stimulate the members to speak out there opinion, doing some training for the inexperienced members and hold some games or travel if possible to promote the communication between different members. For the problem occurred in flexibility groups, sometimes choice the other method to develop a product is much more efficient than agile method, and when the situation fixed the agile method, it can come back and development in agile method. And it is better to hold a brainstorm meeting at the beginning when the deliverable are not clearly ,and the agile manager should take a role to guide the team when the problem cannot be solve by team. For the structure groups, if it is possible to slow down the iteration can be a good choice to let all the team members to follow the progress and understand what they are doing and what they need to do. Setting an automate testing and use pair testing to reduce the cost of testing. And for the location constraint, using the telecommunication tools to maintain the communication, optimizing team size and team mix, understanding the culture and time different will be helpful to work in different location by using agile. Conclusion Agile method is adopt by more and more companies to develop their product, Despite the benefit of using agile method, there are several weaknesses of agile method.
