Kill time and slash budgets with the Value Assessment Method

The Value Assessment Method was designed by researchers to aid the U.S. Army maintenance managers with their preventive maintenance programs. As long as the Value Assessment Method is followed strictly, it can be transferred to serve other companies and organizations with their preventive maintenance systems.

The values of preventive maintenance system activities change regularly, with modifications or phase-outs of systems, changes in needs of installed equipment. The Value Assessment Method is meant to assess the value of preventive maintenance activities regularly before large returns from the activities can be seen in the long run. This allows maintenance managers to respond swiftly should the Value Assessment Method find that preventive maintenance activities are working inefficiently, before losing money long-term on those activities. Maintenance managers can use the Value Assessment Method to justify specific preventative maintenance tasks, as well as determine specific preventive maintenance workload deletions during budget cut periods.

The Value Assessment Method’s activities can be used by most commercial databases. If that database is kept up to date, it can be shared between inspectors and PM technician daily reports. This ensures the data remains current. The data should be used to compile a series of list, which will be applied according to values and constraints determined by the company. Local preventive maintenance managers should appraise their own preventive maintenance workload, as this will allow them to make their own adjustments for unique influences and factors specific to their installation. The lists that will allow them to do this are as follows:

Ordered Preventive Maintenance System Category List:

The most important and simplest list in the Value Assessment Method groups all preventive maintenance system categories into four classes:

  1. a)    Mission and safety (M/S)
  2. b)   Non-M/S categories that are functionally essential for base operations: required
  3. c)    Non-M/S categories that are nonessential but contribute to functional and efficient base operations: needed
  4. d)   Other categories: marginal

General Preventive Maintenance System List

This list includes systems/units from all PM categories and associated PM task. Grouped in the order of Table 1 below. Build your own as follows:

  1. a)    Systems and equipment supported under each category/unit are identified and listed.
  2. b)   All PM tasks associated with each unit are included.
  3. c)    Priority and cost-effectiveness are attributed to each PM task.

Preferred Preventive Maintenance Task List

The Preferred PM Task List is a spinoff of the General PM List and shows a priority ladder for each PM task performed at the time of installation. This list is created by reordering tasks from the General PM List by cost benefit balance and level of the tasks’ parent categories to determine new task orders. Should two tasks have the same cost-effectiveness and parent level, decreasing assignable work hours will determine the order. In a complete Preferred PM task list, each PM task will have a unique sequence number as its label.

Preferred Preventive Maintenance Category and Task List

The Preferred PM Category and Task List is another spinoff. The only difference between this list and the previous is the PM tasks are grouped under a parent category in the sequence number order. It can be used as a modification of the General Preventive Maintenance System List for PM managers’ convenience.

When followed correctly the combined lists of the Value Assessment Method can ease the headaches of even the busiest maintenance managers. However, it requires due diligence and keeping all of the lists updated to be truly successful.
