1. There are a number of reasons why an IS operation plan only covers a single fiscal year, key among them is the ever changing information security environment. Operational planning involves the connecting strategic (long term) and tactical (short term) goals and objectives. In the some current operational environments information threats change on a constant basis what may have been top of the line systems and procedures at the beginning of the year, end up being obsolete only six months later. Thus it may be necessary to update plans and objectives to keep in line with the external environment.

2. CPM stands for critical path method; it calculates the longest path for scheduled activities on a project. It helps determine which tasks are essential for on time project completion and which can ones can be delayed without compromising the project schedule. Some of the key uses of the CPM are:

I. For determining shortest time to project completion.
II. Prioritizing tasks.
III. Project activity sequencing and scheduling.
IV. Project resource requirements.

Gantt charts are visual illustrations of project schedules represented by bars that show the start and finish schedules of the project and major milestones. Some of the key uses for Gantt charts are:

I. Project scheduling and planning.
II. Determining resource requirements.
III. Managing and determining tasks dependencies.
IV. Project control and monitoring.
