work at the time of the work identification. With a priority classification system, you can get the most use from your resources. Assigning a priority designator provides you with an adequate definition of the importance of each job.

You can express the importance of various functions and types of work by assigning priorities using a matrix (table 9-2). After initial use of the priority matrix, review the results periodically and revise priorities, as necessary. The with the highest priority (lowest number) will precede others of lower priority on the schedule.

The priority matrix lists work classifications shown below.

Saftey. Work required primarily for safety reasons.

Function. Work primarily identified with the mission of the activity.

Preventive. Work primarily required to prevent significant deterioration of the plant property or equipment caused by continued use or from natural forces.

Appearance. Work done primarily for preserving or upgrading the appearance of a facility.

Each of these work classifications has three levels of importance. You base the importance level of a particular job on its impact on other jobs in the same classification.

1. High.

Table 9-2. - Priority Matrix

2. Routine. Most work falls into this category.

3. Low.

The PWO or the APWO must give approval for assignment of priority 1 to work. This priority states an overriding emergency, or urgent priority. This priority is an overriding requirement that will insert the final estimated work into the schedule at any point.

JOB ORDER CLASSIFICATIONS

Every specific and standing job order must have a job order number. The Navy Comptroller Manual says that you should keep the number of digits in a job order to the minimum required. This will reduce the chance of error and save time in writing the job order number or expenditure documents and in sorting such documents. This statement also applies when entering job order numbers on the labor job time cards, material requests, and other expenditure documents. For maintenarm management purposes, more than seven digits are cumbersome. The Navy Comptroller Manual states in part:

"No Navy-wide plan of numbering job orders is prescribed because of the variations of requirements in the various naval activities. . . . Generally, all that is required fiscally is a number that will distinguish a job order from all other job orders at the activity and provide an index to the job order itself or to the master card that contains all of the detailed accounting information. Therefore, the number will include in its structure a serial number that by itself or in combination with other codes in the number will satisfy fiscal needs." (See table 9-3.)

Master Job Orders for Housing

When collecting costs by functional accounts or group classification of work (for example, certain types of quarters for which the Navy Family Housing Manual, NAVFAC P-930, sets spending limitations), the reduction of some job order paperwork to a single master job order is possible. This job order will cover several functional accounts performed simultaneously or all the work described on the same work request or inspection report. For example, all the work shown in table 9-4 normally written as seven separate job orders, are combined into one job order as follows:
