Maintenance Tasks - Operational and Maintenance (O&M) costs make up a large portion of the total cost of ownership (TCO), regardless of system "size". It is said that O&M costs make up the lion's share of cost throughout the system's life cycle, and ongoing expenses can determine the economic lifespan of a system. Maintenance tasks can be broken down into four (4) categories:
1. Corrective Maintenance
2. Adaptive Maintenance
3. Perfective Maintenance
4. Preventive Maintenance
The process of "racking & stacking" these maintenance tasks is no small feat; especially for a large system. This is why most firms implement a Change Control Board (CCB; or, you may have heard it referred to as a Configuration Control Board-they are synonymous in nature). Even though the lead systems analyst is typically on this board, they do not decide the priority of these maintenance tasks-however, it is imperative that they understand the nature of each maintenance category.
For this discussion:
1. Properly describe each of the maintenance categories
2. Give a specific example of each maintenance category, either using the class case study or a system that you are familiar with, and
3. Assign each example a specific priority (level 3 being the lowest; level 1 being the highest), based on your knowledge of the system-explain in detail "why" you would give it that specific priority.
