1.) Supporting Activity: Software Maintenance

Review this week's Electronic Reserve Reading, "No Silver Bullet: A Retrospective on the Essence and Accidents of Software Engineering."
Consider that the most difficult software phase of a C2 system is software maintenance. As has been widely documented, software maintenance (e.g., software error correction, adapting to environment changes, and adding new enhancements) accounts for approximately 80% of the software life cycle cost. Thus, the major focus in software development should be directed to constructing highly maintainable systems.

Discuss how you plan for future enhancements to keep the total life cycle cost down especially when few organizations plan for sustainment cost.

2)Supporting Activity: Commercial Software Maintenance

Discuss some major issues when working with commercial software vendors.

3) Supporting Activity: Software Maintenance Types

Discuss how you would prioritize different types of maintenance changes given only a limited number of changes can be implemented in each version release.

To help formulate your response, conduct a search on the maintenance of software, including corrective, adaptive, perfective, and preventive maintenance.

4)Supporting Activity: Disaster Recovery Plan

As you have learned about disaster recovery, discuss some key questions to consider. Provide your thoughts based on what your organization does related to disaster recovery. Describe what you personally do with your own computer. What are some options to consider for an organization to support disaster recovery? In selecting appropriate back-up media, what are some questions that should be considered? What issues should your backup strategy address?

5) Supporting Activity: Enhancements

Discuss what role users have in identifying future enhancements to information systems. How do you capture system enhancement requests and prioritize for the future?
