Narrated lesson · press play
The design is finished on paper — now we build the real system. In this lesson we choose the right hardware and software, code the system to match the design, test it carefully, plan how to switch over, write two kinds of documentation, and finally evaluate and maintain the system so it keeps serving the organisation for years.
What you'll learn in this lesson
By the end you should be able to (NSSCO Computer Studies 1.2):
- Describe the hardware and software required for the new system based on: system requirements and task specifications, cost implications, skills level of staff, including training to use the new system
- Explain the relationship between the system design and the system requirements
- Develop programs (coding process) that are intended to perform tasks in line with the design specifications
- Explain the importance of testing and implementation planning
- Explain the content and importance of documentation of the following system life cycle's components: technical documentation, user documentation
- Explain the need to evaluate the results of the new system against initial specified objectives
- Explain the need of reassessment of the system after a given period to find if it is still performing at the organisation's expectations
