Work Package Development – Feedback Mechanisms
Feedback provides information related to the quality of work in the field, processes that support work, and observation of work practices and conditions in the plant. Feedback is a vital link between the job-site and the organization. Feedback can be obtained through a variety of mechanisms. (E.g. direct observation of work performance, work package feedback sheets, post job reviews, Corrective Action Program, informal communications, etc) These methods of providing feedback on maintenance activities have been used with varying degrees of success.
The maintenance organization should take advantage of as many of these mechanisms as possible. Each will provide a different perspective and insight into the maintenance work process.
Feedback is a credible source of information that can result in the improvement in the organization of work, support worker performance, improve job productivity and identify opportunities to strengthen human performance and reduce errors. It can identify problems with procedures, work packages, equipment, work performance and training of personnel.

Feedback should be obtained as soon as practical following the maintenance activity. It should focus on both improvement opportunities as well as recognizing those things that went well.
Some typical items that should be considered for feedback include:
1. Unanticipated surprises
2. Unanticipated error precursors/traps 3. Industrial safety issues or hazards 4. Equipment condition
5. Personnel issues (lack of resources, incorrect resources, training inadequacies) 6. Work Order/Package quality
7. Procedure quality 8. Quality of supervision
9. Quality of vendor support (if applicable) 10. Quality of planning and scheduling 11. Adequacies of tools, parts, resources 12. Inter-departmental support
13. Obstacles to work performance 14. Things that went well
15. Good catches
Key Human Performance Point
Feedback is a credible source of information that can result in the improvement in the organization of work, support worker performance, improve job productivity and identify opportunities to strengthen human performance and reduce errors.

Work Package Development - References
This section of the work package is the maintenance craftsman’s resource library. This section of the work package should provided sufficient supplemental information necessary to complete the maintenance activity satisfactorily. It is not possible to place all the resource information that may be used during the course of the maintenance activity into the work package. The package would become too bulky and could very likely turn off the craftsman to useful information contained within. However, the work package reference section should contain sufficient information that will be accessed during the maintenance activity and provide reference
information in sufficient detail to allow the craftsman to easily retrieve the reference if required.
In some cases, if they exist, whole or portions of procedures may be referenced. If portions of procedures are included as reference the planner should be careful to include the initial
conditions, precautions and limitations applicable to that procedure to ensure that portion of the procedure is applied appropriately and under the proper circumstances.
References may be included in whole, in part or noted for easy reference and access. Typical references may include:
3-12
Included in package:
1. Approved procedures related to work activity (if they exist) 2. Vendor drawings
3. Complete parts list with appropriate stock numbers 4. MSDS sheets for chemicals that will be used 5. Electrical drawings (if applicable)
6. Copy of the equipment clearance/tag out 7. Operating Experience
8. Any permits required (Confined space, hot work, etc) Referenced or noted:
1. Industrial Safety Manual
2. Detained Post maintenance procedure (if it exists) 3. Hot Work Permit Procedure
4. Confined Work Space Procedure 5. Chemical Control Procedure
6. Foreign Material Control Procedure
7. Technical support Procedures (Packing, torque, welding, etc) 8. Equipment vendor technical manual
9. Specific component vendor technical manual (Coupling, Mechanical seal, etc)
