Computer system plays an important role in solving human problem in their daily life. There are standard steps in order to develop information system called System Development Life Cycle (SDLC). SDLC is the framework available to build a complete system. There are five phases in SDLC which are planning, analysis, design, coding, testing and maintenance (refer to Figure 1 in Appendix 1). The first phase in SDLC is planning. In this phase, the potential system development project is identified. Project manager summarizes all strength and weakness that possible to occur using their professional skills (Hoffer, George, & Valacich, 2008). Next, business plan is defined and documented by project manager in a formal format. According to Burch (1992), business plan must be clear and development of the system must follow the business objective. During this phase, project is selected which decided based on stakeholder meeting with project manager. After that the selected project is initiates. “During initiation, one or more analysts are assigned to work with customer to establish work standards and communication procedure” (Hoffer, George, & Valacich, 2012, p. 116). In this step, lots of information is gained to support project planning by determined project scope and identify project activities which get from ongoing meetings with the clients. Finally, before proceed to the next phase; Baseline Project Plan (BPP) and Project Scope Statement (PSS) are documented based on information gained from previous activities which tells all about the system (Hoffer, George, & Valacich, 2012). The second phase in SDLC is analysis. Analysis is carried out to “gather information on what the system should do from as many resources as possible” (Hoffer, ... ... middle of paper ... ...

It will identify the identified constraints and assumptions of the infrastructure expansion and data warehouse build and design. As with any project it will identify the risks. The Scope of the project will be documented in the business requirements document and all other projects that are associated with this project will be documented.
"In a landmark 1945 essay on "The Use of Knowledge in Society," Frederick Hayek spoke about the time we spend in on-the-job learning, and about the unique "knowledge of people, of local conditions, and of special circumstances" we each accumulate through our work" (Arthur, Defillippi, & Lindsay, 2008, p. 365). The enabling the presence and growth of knowledge workers are the technological developments of information systems to improve ideally the productivity of various tasks. Knowledge is "one of the most important driving forces for business success" (Mansour, Alhawari, Talet & Al-Jarrah, 2011, p. 684). As an IT discipline, knowledge management is experiencing a history and evolution since the early 90's. The composition of the development of knowledge management systems include

The purpose of this Project Management Plan (PMP) is to define the approach to be taken by the AMP Canada case study implementing SAP in 1 year time with the vendor – SAP business partner. The issues identified were: The team implementing the new system were required to meet both functional and systematic requirements thus affecting the implementation of the new system. - The staff were not well trained in the new system. - The user requirements were not taken into consideration thus affecting the purchasing orders, poor management of inventory, the manufacturing and finance department were not integrated.
The Systems Development Life Cycle (SDLC) consists of phases used in developing a piece of software. It is the plan of how to develop and maintain software, and when necessary, replace that software. In 2007 during my hospital’s transition to a new software system, I was fortunate enough to be included in the process. I did not get involved until the implementation phase, but from then on, until now, I remain very active in the process. I decided to highlight the Waterfall Model of SDLC. The Waterfall Model is a “sequential development process” with each phase continuing in a line (McGonigle and Mastrian, 2012, p. 205).

While developing a software many complex activities are required which in turn have dependencies along them. Large software projects require the involvement of programmers, documentation specialists, program managers, architects, database analysts, system analysts, , and trainers and last but not the least testers. Along with their independent responsibilities these persons are also responsible to maintain and keep a check on the software system quality as well.
The systems planning phase is the first phase completed in the SDLC. It encompasses evaluating the feasibility and the cost of the system, identifying the risks involved with implementing the system, and determining the responsibilities of each of the team members. To begin the planning phase, a systems request is submitted to the IT department, detailing the problems and changes to be made in a system. (Rosenblatt, 2014). It is important to note that the request may be a large, significant request, or it can be a smaller, more minor request; however, each request should be addressed using the systems development life cycle. After the request has been made, a feasibility study is conducted that determines the costs and benefits of the new or improved system. The study then recommends a strategy that is best for the system in terms of technical, monetary, and time factors.
To be able to apply appropriate techniques, resources and modern engineering and IT tools (Matlab) towards the assigned question.
Williams, (1997) identified four steps to system planning. Earl (1989) proposed five alternate strategy frameworks which project managers should consider when deciding how the system will enhance the business function. Standard business strategy methods are used to identify such opportunities by using: value chains, application searching and information analysis (Earl 1989).
An architecture for the medical information system called Mental Health Care-Patient Management System (MHC-PMC) to maintain information about patients will need to be developed. The system will be used to give staff information on the patients suffering from mental health problems and their treatments. There are different architecture patterns which can be used to develop the system and there are reasons to use one pattern over another. There is the possibility that any of the architecture patterns used can have short comings associated with it. The architecture could be implemented in hardware and software to meet the needs of developing the new system.
The approved Concept Development document is further defined in the Product Development stage. A fully developed business case can now be reviewed. The Product Manager has gained Concept Approval and can now commence the completion of the PD process. Final approval of the Product Proposal is made by those with approval authority for the cost level involved.
Within the analysis phase a set of goals are needed within the domain. From this there are three perspectives which are taken; the object model the Ronald LeRoi Burback (1998) states “dynamic model, and a functional model. The object model represents the artifacts of the system. The dynamic model represents the interaction between these artifacts represented as events, states, and transitions. The functional model represents the methods of the system from the perspective of data flow.” After the analysis phase the system design phase takes place. Here the system is sub-categorized and appointed tasks and persistent data storage is established, also within this phase the architecture is formed. Lastly the object design phase starts and is where the implementation plan is established and algorithms and object classes are also

The first and most crucial step is to create a solid plan. Plan should include the techniques, tools and data that are going to used in the project. The responsibilities of all the members should be distributed at this step. The utilization of resources and budgeting of the project should be done here. Management tools such as probability and Impact Matrix, FMEA are useful at this point.
