According to the latest CHAOS Report published by Standish Group, only about 32 % of software pro- jects can be called successful, i.e. they reach their goals within a planned budget and on time . Despite the availability of numerous new approaches, companies tend not to take drastic risks instantly switching from their methodological know-how to the agile methods. Instead, companies usually use their in- house know-how based ISD methods that are combi- nations of various methods and that evolved through the lifetime of the company [11, 32]. This happens because of the uniqueness of every ISD project and its environment. Despite the promises of the benefits from agile methods, practitioners are rarely faced with the need to adapt an entire agile method. Companies usually do not want to rebuild their methods and pro- cesses from scratch. Instead, the current demand is to extend their existing in-house methods by imple- menting some useful parts of certain agile methods . The problem is that current agile methods are

Abstract— Agile methods have become popular in recent years because the success rate of project development using Agile methods is better than structured design methods. Nevertheless, less than 50 percent of projects implemented using Agile methods are considered successful, and selecting the wrong Agile method is one of the reasons for project failure. Selecting the most appropriate Agile method is a challenging task because there are so many to choose from. In addition, potential adopters believe that migrating to an Agile method involves taking a drastic risk. Therefore, to assist project managers and other decision makers, this study aims to identify the key factors that should be considered when selecting an appropriate Agile method. A systematic literature review was performed to elicit these factors in an unbiased manner, and then content analysis was used to analyze the resultant data. It was found that the nature of the project, development team skills, project constraints, customer involvement and organizational culture are the key factors that should guide decision makers in the selection of an appropriate Agile method based on the value these factors have for different organizations and/or different projects.

OALibJ | DOI:10.4236/oalib.1100579 2 June 2014 | Volume 1 | e579 Rapid Application Development Model (CORADMO) attempts to quantify both the positive and the negative ef- fects of key schedule drivers, and thus enable planners to estimate the relative schedule that will result from va- rying these parameters. CORADMO is a derivative of the revised Constructive Cost Model (COCOMO II) , this was calibrated against larger projects that were typically optimized to reduce cost. In contrast, the goal of projects using agile/lean techniques is often to compress schedule. But in this sequence still we do not have any desire cost estimation technique for Rapid application development for agile methods. For dealing we construct new method for agile name is Corad-Agile (Constructive rapid application development method for agile), for this concept we are using agile methods (SCRUM, DSDM, ASD and AUP) and using scale factors of COCOMO- II with COCOMO-II extension CORADMO cost drivers.

Practitioners argue that incremental approaches reduce initial time to mar- ket and improve resilience to change during development programmes. In plan- based methods “you go for a requirement analysis, then design, and then cod- ing. And by the time you actually go for delivery. . . the market situation has changed” (Scrum Master, Company F). Reducing time to market and getting feedback on product releases is attractive, “[we want to] come in the market as soon as possible. . . with newer ideas” and “you don’t know your customers face- to-face, so it’s pretty critical to get the product out [and] get their feedback” (Engineering Manager, Company B). However, agile methods are less attrac- tive for when negotiating between external providers, “in systems integration we need to interact with multiple vendors. . . they don’t have any knowledge of agile” (Engagement Manager, Company G).

Right now, I'm doing some consulting for an organization that had someone else develop their web site (mostly intranet and extranet). They did it waterfall: big contract, big requirements doc, possibly big design doc, big price tag. The project is very late, parts don't function, other parts function very differently than what the organization needs, and still other parts are almost physically painful to use. The customers have literally never seen the people who are actually creating the system. The saddest part is that the customers' manager, while not at all experienced in software development, is a big fan of approaches like XP: incremental progress, iterative steering, and no solo work. The developers had to argue him into the waterfall, big-bang approach. Not all of the problems with the latter project are due to using a non-agile method, but most of them are. And an agile method would have ameliorated most of those problems: e.g. the customer could have had half of the features a year ago, which would have given them a lot of value (I explicitly asked them this) (T287:310).

The main reason behind selecting the Agile method is the simplicity of this strategy which is rapid development without too much need of documentation in case of the android application we need to build, check, correct, rebuild, test continuously and every time we make changes we need to go through these steps to verify the results of our work. Agile methodologies including programming, development and project management involve simplifying the software development into small modules, while combining documentation and quality testing at every step. The regular waterfall methodology includes judging the requirements ahead of time with testing and documentation as end steps rather than being the crucial part of development. This methodology provides improvement techniques that are effective and profitable for portable applications advancement.
Agile is a process in which agile methods and key values are developed by a team who are distributed in the same place and out of place. Agile methodologies work with the distributed environment for development of efficient software using agile practice. Agile approach is dependent on cross functional and self- describing team which have good communication and collaboration between the team members and customers. Customers resented in one place builds the trust between the teams. The waterfall model also used by the distributed teams but in waterfall model each stage work separately and commitments are made earlier and it is difficult to react with late changes in the requirement. In agile method, Product completely developed and tested at the same time means, we have to perform coding and testing together in single iteration. Agile perform one or more iteration for product development in every week. Many methods are used but mostly scrum and extreme methods are used in programming. In scrum, software is implemented using sprints with planning and iterative process. Each sprint starts with developers, testers and sprint manager in a week when product developed, product is sending to customers for reviews in the end. In scrum, one or more sprints are performs for a small period of time with detailed plans and backlog. In backlogs, all sprint information, daily meeting information for close communication between team members with scrum master are stored and product manager is used for developing the software.
lesser extent: automated unit tests (the project strives to use test driven development), pair programming, refactor- ing, release planning (occurs in irregular intervals), short releases, continuous integration, coding standards, collec- tive code ownership, simple design and regular meetings (weekly), and a Kanban board. Developers of the project are mainly students, but there are many international con- tributors, who, e.g., provide translations for the user inter- face, bug reports or feature requests. With this work we focus on the experience of the contributors. Do they ben- efit enough from integrating new practices, so the addi- tional learning is worth the effort? FOSS projects try to keep the entrance barrier as low as possible and you would not want to drive away possible contributors by imposing practices on them, which do not provide much benefit to them. Thus, this paper attempts to answer the following Research Question (RQ) “Can FOSS projects benefit from using agile methods like the Kanban Method?”. To answer this question we will focus on different aspects and try to answer three sub-questions,

If educators adopt a form of agile pedagogy they also need to think about how capabilities and skills can be developed through real or simulated activities that are negotiated by learners and recognised by all as leading to valued functioning’s. The difference between operating scrum as a learning methodology at work and in schooling is that formal education is predominantly about developing emergent capabilities and working and learning in a connected environment whereas in work one could assume that team members already possess varying degrees of expertise. Commentators often decry formal education without really putting forward any concrete alternatives. Not all children can self learn in public spaces or become coders or entrepreneurs, and mass schooling will not disappear in a digital whirlwind of change overnight. Agile learning methodology is a potential answer to transforming schooling from within by keeping structure but releasing agency and control within it by providing participant practice identities within a project. As such, agile learning is a learning design, a process and therefore a technology in its broadest sense which widens the range of skills and capabilities that can be evidenced within the school setting. It is about looking at what students can do and letting them contribute purposefully whilst also allowing opportunities to develop, from peers and teachers and experts on the net, the things that they cannot do. This paper is a first step towards validating the use of scrum and its potential as a working solution for emancipation and change within mass education.

According to , the Waterfall model is the most commonly used methodology, it is a linearly sequential model where the completion of each step is imperative to commencement of the next, and the requirements for your application have to be very clear before commencing the development. In summary, the steps involved in Waterfall methodology includes planning, analysis, design, implementation, testing and maintenance. This method is very clear on requirements before development commences. In Waterfall, each phase completes before the next, and it requires minimal resources, and thorough documentation . They also found out that this methodology is faulty because problems from one phase is transferable to the next.
Even though the visibility of the benefits is different from team to team within companies, the overall perception is that agile methods have brought several advantages to software development in these companies. In first place, customers became more satisfied with the frequent deliveries of value, as interviewee B stated: “We are delivering what the customer needs and reducing the feedback loop”. This benefit is in line with the sense of time-to-market and productivity pointed out in the survey results. Another benefit is the customer collab- oration along the software process as a shared responsibility. Regarding this aspect, company C outlined the bad experi- ence of customer collaboration on government, “In the end, the collaboration was of no use and all apparently flexible scope with which we were dealing with. What was valid for government was only what was determined in the contract”. As companies become more experienced in agile meth- ods, the benefits of software quality, project visibility, and team morale were confirmed by the interviewees as being increasingly perceived since its implementation. The quest for continuous improvement has increased technical excel- lence of team members. As a consequence, software quality has enhanced in their perception, as interviewee A outlined, “The issue of quality: now we have a defined cycle and the feeling of more collective ownership and more internal code quality”. Also, job satisfaction and visibility are other aspects raised by the interviewees when getting mature in agile meth- ods. For instance, interviewee B stated, “People are happier, people understand what they are doing, the corporate climate is coolest”. In Company G, the perception of benefit is sim- ilar. The project is owned by the team. Some people became more motivated with agile methods. People are more creative and deliver what makes the difference for the client. These qualitative evidences reflect on the strong correlation found between the most perceived benefits and company experience raised in the statistical analysis (Table 9).

Project management is the process of defining scope, deciding on methodologies, creating teams, and all of the other project management processes defined in the PMBOK® Guide. When Agile is chosen as the product development methodology for a project it will certainly influence the way the project is planned, resourced and controlled but of itself, Agile is not ‘project management’. Projects are delivered by temporary teams assembled to work on the unique project deliverable (as described in the Project Charter) and then reassigned to other work as the project closes down.

According to Saunders’s research onion showed in Figure 3.1, the research needs to start by defining the research philosophy as it helps in creating a starting point for the selection of the appropriate research approach, which according to them is the second step of the research process (Saunders et al., 2007). Once the researcher has selected the research what research approach they will be using they move on to the next stage of the research process in which they will decide what research strategy they will use, that is what plan they will follow to answer their research questions. The fourth step is deciding the research approach that will be used by the researcher, that is are they going to use mono-method, mixed method or multi-method. The fifth step is defining the time horizon for the research, as that will determine the time frame for data collection. The last step according the research onion is data collection, in this stage the researcher decided how he/she will be collecting data for their research, is it going to be by using primary data or secondary data.

The improvement of the technologies nowadays had helped a lot in our daily lives such as in medical, education, business, banking and entrepreneurship. We focused into Hospital Patient Information System (HPIS) since it is the subject of interest for my research. Today, there are many medical software system but there are less secure and the interface design are less suitable for the user. The author  concerns on the legal or ethical when developing clinically applied technologies, the data collection and analysis in order to improve the Cardiovascular disease. We can get opportunity from medicine system development of improving different steps in medical practice, from diagnosis to healthcare management and clinical research. In the clinical decision- support system (CDSSs), it is developed by  to store and manage the clinical data, tools to alert clinicians of problematic situation or decision making tools to help the clinicians by mapping it with electronic health record (EHR). The author  has created an analytics platform for specifying and detecting clinical phenotypes especially on derived variables in EHR data for quality improvement investigations. Curently, our application only store and retrieve the information for patients. 2.2 Agile Approach Method
Abstract: “Change is inevitable, growth is optional” said by a John C. Maxwell and in software engineering this sentence exists very truly. In last decades, remarkable progress has been done and Agile Software Development is the result of that changing environmental needs and efforts of researchers to overcome the traditional model of software development. Agile development is modern approach which deals with rapid delivery of quality software and full involvement of customers, so the requirement of customer can be fulfilled and achieve the goals. This review paper include different approaches of agile and risk management in agile.
The Development Method Selection Framework (DMSF) can be used to predict the methodological domain for the project-in-hand by gathering project characteristics in the form software parameters or metrics. Weights are assigned depending upon the role of these metrics on the software development. The process is helpful for the organizations to save on huge losses incurred upon the failure of projects caused due to wrong selection of process models. Proposed framework is supported by the decision support system realized with the help of feed- forward back propagation neural network architecture of artificial neural networks. In the future we intend to improve the selection process using different machine learning algorithms like Random Forest, Logistic Regression and Decision Tree to ensure more accurate and precise results.

With the recent introduction of Agile project management methodologies such as Scrum, proponents argue that these problems can be overcome , but the author was interested in studying whether, particularly in the Sri Lankan context, a quantifiable improvement has been made with the transition into Agile methodologies. Agile methods provide ways to develop software which place emphasis on people and their creativity . Despite the benefits that Agile can deliver, little work has been published regarding its current usage in Sri Lanka . If the methods are to be used, there is a need to understand how Agile methods are being practiced within this region. How is the practice perceived by the practitioners in Sri Lanka? What challenges and benefits have they experienced when using the methodologies? How they overcome those challenges? Agile methods are not for everyone. In one of the sessions for an invited talk at the XP2011 Conference, titled ‘When Agile is not enough’; the speaker stated: “what works in one culture, will not necessarily work in other cultures”. The team agrees with this statement and intends to investigate the scenario in the country. Several studies stated that addressing cultural differences is important for the success of software development [5, 6]. One study  although the paper discussed global software development, it is believed that some cultural aspects discussed in the paper can be related to the usage of Agile methods.
The conclusions are as follows: 1) Education and train- ing play a positive role in promoting successful imple- ment-tation of agile process improvement. 2) Agile me- thods must be established within agile culture, mainly refers to mutual trust and cooperation of the corporate culture. 3) Attention to the design and application of advanced technology do not receive widespread support. We suggest that too much emphasis on the importance of design and technology is not correct in P company. In the end, we use applications knowledge creation theory to analyze the open source software community with suc- cessful application of the typical agile software method, propose ten principles of knowledge creation in open source software community, features of knowledge crea- tion in open source community, case study for Apache server development, and we hope that more researchers could join in the study and practice.

ensures a simple operation for certain complicated projects. This method completes the addition of new requirements, updates automatically to varying requirements delivery of tasks. The completion of the project according to the priorities and delivery can be viewed by the project manager. This allows the director to have a compare the price and estimated time to complete the project within the expected date and budget estimation specifically at the end of the project.
Table 1 represents some macro level factors to increase the quality of agile project. Some questions based on organization involvement, proficiency of team. If tem player is present in the project then give reward to encourage the person. To increase the productivity observes the matured story point and to increase the technology maturity organize the expert for it. In agile involvement of customer does matter. So to increase the quality find whether the customer representative is IT savvy. Also need to consider the tool training provided as a quality factor
