systems. That is; the system anaylsts ensures that new technical requirements are properly integrated within the existing processes and skill sets.

  1. It is worth noting that for a steady operation of the system, a systems analyst may be required to plan a system flow from the ground up.
  2. This will include the all-important interaction with the customer and the internal users to learn and outline requirements that will be ultimately used to produce business requirements documents.
  3. Document requirements and to some extent contribute to user manuals.
  4. A system analysts is a technical employee hence is responsible for writing a technical requirements from a critical phase of the system.
  5. Interacts with designers to understand software limitations.
  6. Performs the vital systems testing
  7. Help programmers in providing flowcharts, use cases or even database design during system development.
  8. A system analysts is responsible for deployment of the completed system.
  9. A system analyst is responsible for designing components and providing information to the developer.

QUESTION TWO

Components of the information system

  • Users-these are people who use the system such as the customer and the cashier.
  • Hardware-this includes the machines employed in the system such as in theCBS, DDS App
  • Inputs where information is fed into the system.
  • Telecommunication-links different components such as the users, the
    inputs, outputs to each other.

Barry Boehm is a software engineer who came up with the spiral model of developing systems. According to Barry, the spiral model as a process model generator. The generator enables the establishment of choices based on a project’s risks that ensure proper generation of an appropriate process model for the project.

Methodologies for implementing a system.

Agile software development methodology. In this model, the development is done in cycles with each cycle advancing from the previous phase.

The spiral model methodology-this model comprises of the planning phase, the analysis phase, the engineering and the evolution phase. The system to be created goes through all these stages repeatedly.

Waterfall model- It
is done in phases with each step
being fully completed before moving on to the next step.
