Explain the Process of Project Management
A project's management is based singly on the idea that projects go through various phases that are characterized by different sets of tasks and activities that ensure the project moves from the conception stage to its conclusion. A project may be huge or small, have cost or time constraints and be of a certain level of complexity and so it is crucial that a sound approach is used in managing the whole life cycle of the project. Project management has 5 phases (Pathak, 2014):
Project Initiation
This is when a project is begun formally, given a name and the scope defined. The stakeholders involved do their own analysis and decide if the project is worth pursuing. Given the project's nature, the experts may do a feasibility study. If it is an IT project then they may perform requirement gathering and also do an analysis (Pathak, 2014).
Project Planning
During this stage, a plan for the management of the project is crafted. The project management plan will take into account the entire unit plans for scope, resources, risk, communication, quality and cost. The key activities involved in the phases are the coming up with a schedule, GANTT charts, estimating the resources required, planning communication means, assigning activities to dates and coming up with deadlines and timelines. It is necessary that a plan is put together as projects have risks, both unidentified and identified, that may impede the project later on. Risk management planning takes identifying risks and putting in place a mitigation plan for those risks (Pathak, 2014).
Project Monitoring and Control
The phase involves mainly measuring the performance of a project and the progress made relative to the project management plan. Scope verification is done to check for change control, scope creep so as to track and ensure the change requirements of the project are well managed. The cost plans are paid attention to and the variations from the plan are looked into to ensure they don't take the project off-track (Pathak, 2014).
Project Closure
This marks the official closure of the project. A series of tasks are carried out at this stage. Deliveries are made, resources relieved, workers rewarded and recognized and the contract and project team are formally terminated.
Explain the Systems Development Life Cycle and how it is used in HCIT
The systems development life cycle (SDLC) is used in software development to define the various steps in the process of software development. It covers the initial stages right from the carrying out of feasibility studies to the final stage of the project. A team of developers in an organization in charge of building software follows the structure provided by the SDLC. SDLC describes in detail how the software will be developed, maintained and replaced. The methodology to be made use of for software improvement, quality assurance and the general development is defined clearly in the life cycle. Various organizations make use of different development models: Annual Change Traffic (ACT), Extreme Programming (XP), System Development Lifecycle (SDLC), Agile…
Systems Development Life Cycle has historically been a very useful tool in the development of software and operating systems in Computer Information Technology. Through the Systems Development Life Cycle there are at least five distinct phases that are delineated and performed within a linear patter. Meaning, that each step must be complete or at least very close in order for the next set of experts to begin the next phase
However, the company did feel it should develop its own Database infrastructure that would work with the new underlying database management system and would mesh with existing organizational skills and the selected enterprise software solution. Because the company followed a standardized implementation process, they were able to successfully reengineer their existing business structure. The objective of the System Development Life Cycle is to help organizations define what an appropriate system
system development life cycle (SDLC) approach to the development of Information Systems and/or software is provided. An explanation of SDLC is offered, with different models applied in implementing SDLC delineated. Advantages and disadvantages associated with each of the models will be identified. System Development Life Cycle According to Walsham (1993), system development life cycle (SDLC) is an approach to developing an information system or software product that is characterized by a
Systems Development Life-Cycle is a framework for an evolution from abstract ideas to a concrete reality Systems development life-cycle (SDLC) is a structured process of systems development is an evolutionary process that proceeds from a broad concept of information requirements and finally ends into the manufacturing of a product -- development of a new system. From this conception it can be seen that the ideas of SDLC begin to narrow
Software Development Life Cycle ( SDLC) Explain Requirement process ( in SDLC) in detail. Why is this exercise important? Requirements engineering is a fundamental activity in systems development and it is the process by which the requirements for software systems are identified, systematized and implemented and are followed through the complete lifecycle. Traditionally engineers focused on narrow functional requirements. Now it is being argued by Aurum and Wohlin (2005) that focusing only
This process places the user in a central position for both determining system requirements and ensuring they are met. The benefits of these systems include not only improvements in user efficiency, but also others, such as reduced training costs, reduced user errors, reduced maintenance costs, and increased customer satisfaction. However, the chief requirements in these kinds of systems become to understand the users' information needs. As we argued earlier, the systems
