Question 3

Illustrate and describe the maintenance life cycle proposed to the case.

For the case study of insulin pump, our team proposed the post-delivery stage of

software maintenance life cycle processes. In this type of software processes, there are 7

maintenance stages or phases that insulin pump software project needs to go through.

Post-Delivery Stage

1. Classification and identification stage

This is the first stage where software preparation and transition activities, such as

the conception and creation of the maintenance plan; the preparation for

handling problems identified during development; and the follow-up on product

configuration management.

For example, modification request is needed for the insulin pump system which is

the problem regarding sensor.



2. Analysis stage

In this phase or stage, problems and requirements of the insulin pump software

need to be analyzed and identified before it can proceed to design phase.

As for example, client gave a feedback that the insulin pump has a problem in

measuring the level of sugar in the human body. So, it is required to be repair of

its sensor problem and maybe the bugs that disturb the sensor.

3. Design stage

After problems and requirements are gathered, our team will make a design

which is suitable to overcome the problem and improve the insulin pump

problems.

For example, the structure of the system should be improve and change

accordingly what is best for the system to have a better sensor so that the same

sensor problem could not be repeated again.

Estimated life span: 2 months.

4. Implementation stage

The implementation process contains software preparation and transition

activities, such as the conception and creation of the maintenance plan; the

preparation for handling problems identified during development; and the follow-

up on product configuration management. For example, after the design has been done, it is time to implement the design

of the insulin pump whether it is suitable for the problem arises or not.

5. System test stage

This is where the internal of the system will be tested. It is said that the system

test will test overall of the fixed and all of other parts.

For example, if the insulin pump had the sensor problem, this phase will test

overall system and this is how we can detect other problem that might arises

after improved and change the system of the insulin pump.



6. Acceptance test stage

This stage is a phase where all the members of the team will be grouped and a

discussion will be conducted to state whether the maintenance of the insulin

pump will be accept or not.

For example, if the insulin pump got other problem, the system should not be

moved on the next stage.

7. Delivery stage

This phase can be also known as deployment stage where the insulin program or

system will be deployed as an execution program.

For example, when everyone or all members in the team accepted the improved

insulin pump system, it is the time where the system is ready to be delivered and

deploy as an executable program which it is more suitable for the end-user.
