Maintenance
Once the system is installed into the organisation it will need to be maintained. There are three different types of maintenance that can happen to a system.
Activity 3 – Sort the Maintenance cards with their definitions. (Paired – 5 minutes)
Activity 4 – Make note of these maintenance and come up with appropriate examples (Independent / Paired – 10 minutes)
Answers to be briefly discussed as a group.

8. Review / Evaluation
At the end of the project it is important to evaluate the system. The created system is evaluated against :
Client Requirements
Quantitative and Qualitative Objectives
Users / Clients opinions on project delivery
It would also include project members own opinions about the progress of the project as a whole.

9. Methodologies – Odds Vs Evens
In Systems Development there are 2 main methodologies that are adopted. The methodology is either Linear or Iterative.
Activity 7 (Paired – 10 minutes)–
ODDS are to read the passage on linear methods
EVENS are to read the passage on iterative methods.
When informed ODDS are to pair up with an EVEN and share your learning.
Between you complete the tasks outlined on your passage sheet.
Answers to be briefly discussed as a group.
