Systems Acquisition Plan
Description
The System Development Life Cycle allows users to change a newly-established project into a functional one. SDLC is a multistage and iterative process, which is designed systematically. It divides complicated projects into tinier and more manageable phases, enabling managers to validate the successful accomplishment of a project’s stages before assigning resources to the ensuing steps. The SDLC process is applied in modeling or providing a plan for technical and even non-technical to make a high-quality system that fulfills the expectations of a business or even manages decision-making advancement. Initially, the Systems Development Life Cycle was comprised of five phases.
However, the phases have currently increased and are seven of them. The increment of the steps assisted systems investigators to describe or explain more explicit actions for achieving particular goals. The SDLC is similar to the Project Life Cycle in that it employs a systems plan of action to illustrate a process. The action plan is frequently applied and followed when an IS, or information technology is under development. The Systems Development Life Cycle highlights various stages of the advancement or development process. The life cycle action plan is employed so that users can see and comprehend the activities included in every stage. The action plan is also applied to let users become aware that a step can be redone whenever a system needs improvement or modification.
Summary of Phases and Participants
- Initiation Phase
He initiation stage starts when a favorable chance to add, make better, or perfect a system is singled out and officially requested via a business case presentation. The business case is supposed to explain a proposal’s intention, describe expected gains, and illustrate how the suggested system backs up one of the organization’s business approaches. It should also describe alternate solutions and explain numerous informational, operational, and network needs. The participants involved in this stage are the Executive sponsor, project sponsor, business owner, project manager, and project stakeholders.
- Planning
Planning is the second systems development procedure’s stage. It determines whether or not a new system is needed to accomplish the strategic objectives of a business. This stage is the first or initial plan for an organization’s business initiative to obtain the necessary resources to expand or broaden an infrastructure to make service better. The organization could be attempting to fulfill or even exceed its workers, customers, and even stakeholders’ expectations. This stage’s main intention is to discover the extent of the issue and come up with excellent solutions. Resources, prices, time, gains, and various items are supposed to be considered in this stage. The participants involved in this stage are the project manager, project sponsor, and various business representatives.
- Systems Evaluation and Needs
Systems evaluation and needs are performed in the third stage, whereby businesses work on or evaluate the origin of the issue or the transformation need. In the event of an issue, potential solutions are presented and scrutinized to determine the best suitability for the eventual project’s goal or goals. In this stage, teams consider or contemplate on the operational needs of the undertaking or the solution. Also, systems analysis occurs in this stage. The end-users’ requirements are analyzed to make sure that the new system can fulfill their needs. Systems evaluation is crucial since it determines the things that a business requires and how the requirements can be fulfilled. It also determines the individuals that will be accountable for individual project’s pieces, and the kind of timeline to be anticipated or expected. Several tools that are particular to this stage and can be used by businesses include Computer Aided Systems/Software Engineering, requirements gathering, and structured analysis. The participants involved in this stage are business representatives, business analysts, and also the project manager.
- Systems Design
The systems design stage explains comprehensively the essential specifications, operations, and even features that will gratify the recommended system’s operational needs, which will be set up. In this stage, the end-users talk over and even decide on their particular business information requirements for the recommended system. They also consider the crucial components, structure, and procedures that will assist the system in accomplishing its objectives.
- Development
The development phase is where the actual work starts. It is where the programmer, the database developer, and the network engineer get involved in accomplishing the main task on the undertaking or project. The job involves the use of a flow chart to make sure that the system’s process is perfectly organized. The development stage marks the initial section’s end of the procedure. Also, this stage indicates the beginning of production, and it is distinguished by instillation and transformation. Concentrating on training could be highly beneficial in this stage. Participants in this stage include network engineer, database developer, and the programmer. Developers, business analysts, project managers, and even designers are also included in this stage.
- Integration and Trial
System integration and even testing of programs and processes are included in the sixth stage. These activities are conducted by a Quality Assurance expert to find out if the suggested design fulfills the initial or starting business goals’ set. Testing could be repeated particularly to check if there are errors, bugs, and even interoperability. The testing is carried out until the end-user considers it acceptable. Verification and even validation are also included in this stage since they assist in making sure that the program is completed successfully. Participants in this stage include testers, developers, various business representatives, business analyst, and project manager,
- Implementation
In this stage, a large part of the program code is written. Also, the stage includes the actual newly-developed system’s installation. The project is implemented by way of shifting the information and constituents from the previous system and into the new one through a direct cutover. That could be a dangerous and complicated move. However, the cutover generally takes place at the time of off-peak hours hence lessening the danger. Participants in this stage include the release manager, testers, project manager, and developers.
- Functions and Maintenance
In this final stage, maintenance and even frequent required updates are involved. The end-users can also make improvements or polish up the system to increase performance, add different abilities, or fulfill more user needs. Participants in this stage include various business representatives, the project sponsor, and the project manager.
