The Seven Phases of System Development Life Cycle (SDLC)

The Seven Phases of System Development Life Cycle (SDLC)

Question One

The System Development Life Cycle (SDLC) is a systematic and iterative approach for turning newly-developed projects into operational ones. The process involves seven phases through which the developer operates with the aim of achieving goals and objectives. The seven steps are:

Planning Phase

At this stage, the developer defines the scope of the project and estimates the costs of each phase. The objective of the planning phase is to establish project estimates in terms of costs, time, and resources. The developers devise a strategy through which they intend to achieve the goals of the project.

System Analysis and Requirement Phase

The developers outline the requirements from stakeholders and experts. In other words, they analyze stakeholders’ needs and expectations to ensure that the system addresses their preferences appropriately.

System Design and Prototyping

After outlining the needs and requirements of the stakeholders, developers proceed to design the blueprint or prototype. They create a precise and creative design that incorporates the data structure and design of the database (Lemke, 2018). The main output of the stage is the design document or the blueprint of the system.

Programming

The programming stage is the critical phase where the planners begin their development work. They establish a code that is the basis of the system. At this point, different programmers receive their tasks and work on specific units of the project. Developers do the actual coding at this step (Lemke, 2018). It is the most crucial stage as it is where the new system begins.

Integration and Testing

At this phase, different outputs from specific coders come together to form the new system. The integration process also involves an examination to determine whether the new system addresses user needs and requirements. Quality analysts evaluate the capability of the project.

Deployment

After attesting that the project meets the requirements of the users and stakeholders, the quality analyst gives the go-ahead for the deployment stage. At this juncture, users get to interact with the new system.

Implementation and Maintenance

The project development team hands over the system to the users completely but retains the monitoring and maintenance functions.

Question Two

There are two primary classifications of software development strategies. The first is traditional development methods, which involve a clear outline strategy. The other one is agile software development strategies. It is more flexible and customer friendly. The main difference between the two approaches is the sequence of phases that each method follows (Tripp, Saltz, & Turk, 2018). Traditional methods have a documented flow of steps while agile methods allow flexibility to accommodate the changing needs of the stakeholders. The best alternative methodology is the active group of strategies. Agile software development schemes focus on the final user of the system.

Question Three

The main reasons why projects fail are lack of clear project objectives and visibility. When the project leader or the director has no clear view of the project requirements and goals, it becomes difficult to proceed with the venture. Thus, the stakeholders and developers may lose interest in it. The best way to avoid failure is through planning and setting of objectives and requirements.

Question Four

The best android software would focus on the home budget for employees. Most financial management software focuses on organizations but leaves out individuals. Employed people receive their income regularly and on a specific date. Thus, they can manage their finances and set objectives for the expenditure, savings, and investment. Having an application that guides employees on how to utilize resources would increase productivity and motivation.
