...System Development Life Cycle (SDLC) SDLC is a set of activities which are perform by analyst and developer to create the system for software. SDLC is a conceptual model used in project management that describes the stages involved in information system development project from a preliminary study through maintenance of the complete application. SDLC follows six steps-: 1 Preliminary study 2 Determination of system requirement 3 System design 4 Software development 5 System testing 6 Implementation & Maintenance 1 Preliminary study -: Preliminary investigation is the first step in the system development life cycle. The preliminary investigation is a way of handling the user’s request to change, improve or enhance an existing system. The objective is to determine, whether the request is valid and feasible before any recommendation is made to do nothing, improve or modify the existing system, or build altogether a new one. Preliminary study divided into following 3 categories – A. Request Analysis B. Feasibility study C. Request Approval Request Analysis:- In this category, the users need is clearlyIdentify. Analyst identifies that what are the requirements of the user. Feasibility study:- The aim of the feasibility study is to access alternative systems and to propose the most feasible and desirable system for development. Thus, feasibility study provides an overview of the problem and acts as an important checkpoint that should be completed before committing more...

...1) An ATM SRS has a requirement to allow for cash withdrawals in $20, $10, and/or $5 denominations. a) Name the stakeholders for this system. (10 pts) Below are all the possible stakeholders from the beginning of the development phase to the end phase. ATM Engineer - Maintenance of the equipment by the bank’s engineers. This action may be initiated by the engineer on a routine basis. It may also be initiated by the equipment that can call the engineer when it detects an internal fault. Property / Shop Owners: Unloading of deposits and loading of cash by officials of the ATM owner. These actions occur either on a scheduled basis or when the central computer determines that the cash supply is low or the deposit receptacle is liable to be getting full. This stakeholder group concerns people who might live next to or close to an ATM machine. For example, many ATM machines can be found on the high street and perhaps only a few floors above will be someone's property. This group also includes shop owners as many ATM machines can be found located next to a shop. Audit: An audit trail for all activities will be maintained and sent periodically to the bank’s central computer. It will be possible for the maintenance engineer to save a copy of the audit trail to a diskette for transporting to the central computer. System Test Engineer – Bothe dialup and leased line support will be provided. The ATM will continue to provide services to customers when communications with the central...

...tips for selecting the best Commercial Off The Shelf (COTS) software product Article by Prinicipal Consultant Thomas Hornbæk Svendsen, NNIT Selecting a Commercial Off The Shelf (COTS) software product is usually a demanding process. Not only does it require clear objectives and goals, but also a dedicated group of key stakeholders with substantial business process insight. Moreover, to ensure the process is successfully planned and completed, it’s necessary to use a transparent method to document decisions and capture learnings and decisions. The organisation you work for probably has a more or less well-defined process for acquiring COTS software products. Normally, this will include a policy for how to engage in such a process, and a governance-structure for budgeting and decisions. The supporting process-descriptions will vary from organisation to organisation – you might find a detailed and transparent process – or the opposite, that the process is only defined in broad terms, leaving it up to you to define the concept and approach. In case of the latter – how do you get the process right? It’s up to you – perhaps together with a group of colleagues – to ensure that the financial requirements are adequately balanced against the requirements for business process support, that the organisation’s business imperatives are met, and that all relevant stakeholders are adequately involved. Furthermore, if the COTS software product is for a GxP-validated setup, you must ensure that...

...testing is one of the most popular methods for software testing. It is integrated automated process by which standalone units of any source code are tested by control data, usage procedures, and operating procedures. The whole process is done in order to determine whether software is good enough for usage. Unit tests are created by programmers or occasionally by white box testers during the development process. The process of unit testing is simple and hassle free as compared to any other form of software testing. Each test comprised in total testing procedure is different and independent from another. There could be various substitutes like method stubs, mock objects, fakes and test harnesses which could be implemented for proper independent checking of software independently. Software developers and designers write unit codes which act as building blocks of any program. These test runs are directed for achieving pre determined objectives of any program. While a developer writes any unit code for software development, he takes account of various permutations and combinations and accordingly writes the source. But actual implementation is possible only when that code is tested in working environment. There could be inherent errors in the software development which are caught only during this phase of unit testing. Implementation phase of unit testing is the most crucial phase as various processes could be used during that phase. Its execution can vary from being very manual (pencil...

...with business processes. he language-action perspective (LAP) has contributed to several models of coordination of work. In the seminal work of Winograd and Flores [12] the conversation-foraction (cfa) scheme was introduced. This scheme describes, as a kind of generic construct, how two actors come to an agreement about what is to be done. There is someone who asks for the work and someone to perform the work. There are several approaches to business modeling following the cfa scheme. The two most famous approaches seem to be Action Workflow [9] and DEMO [1]; see the article by Dietz in this section for more on the DEMO methodology. The general idea is to get a business model of how people, through conversation, coordinate their work. Such a business model, focusing on coordination, should be seen as foundational for the development of supporting software. The LAP spirit is to consider software as a tool for coordination. COMMUNICATIONS OF THE ACM May 2006/Vol. 49, No. 5 53 Action Workflow and DEMO are general business imply. BAT is a generic model for describing busimodeling methods based on LAP. They can be used ness interaction between a customer and supplier for modeling coordination within one organization (see Figure 2). It describes business interaction in (intraorganizational coordination) and can also be terms of four phases of a business transaction: proused for modeling coordination between several orga- posal phase, commitment phase, fulfillment...

...The General Model-Software life cycle models describe phases of the software cycle and the order in which those phases are executed. There are tons of models, and many companies adopt their own, but all have very similar patterns. Each phase produces deliverables required by the next phase in the life cycle. Requirements- This phase is the main focus of the project managers and stake holders. Design-The software system design is produced from the results of the requirements phase. Implementation-Code is produced from the deliverables of the design phase during implementation, and this is the longest phase of the software development life cycle. Testing-During testing, the implementation is tested against the requirements to make sure that the product is actually solving the needs addressed and gathered during the requirements phase. (CIO.2002). Waterfall Model-This is the most common and classic of life cycle models, also referred to as a linear-sequential life cycle model. It is very simple to understand and use. In a waterfall model, each phase must be completed in its entirety before the next phase can begin. At the end of each phase, a review takes place to determine if the project is on the right path and whether or not to continue or discard the project. Unlike what I mentioned in the general model, phases do not overlap in a waterfall model. (DOJ,2003). Advantages- Simple and easy to use. Easy to manage due to the rigidity of the model – each phase has specific deliverables...

Higher-level mechanisms can be more expressive, but also tend to be more vulnerable to attack, for a variety of reasons ranging from intrinsic complexity to implementer skill levels. Most attacks involve the opportunistic exploitation of bugs; and software that is very large, very widely used, or both (as with operating systems) is particularly likely to have security bugs found and publicized. Operating systems are also vulnerable to environmental changes that undermine the assumptions used in their design. The main function of access...

Organizations use a standard set of steps, called system development methodology to develop and support their information systems. Like many processes, the development of information systems often follows a life cycle. For example, a commercial product such as a Nike sneaker or a Honda car follows a life cycle; it is created, tested and introduced to the market. Its sales increase, peak and decline. Finally, the product is removed from the market and is replaced with something else. Many options exist for developing information systems, but the most common methodology for system development in many organizations is system development life cycle. However, it is important to know other alternative development methodology available in order to...
