Procurement Quality Assurance

Quality Metrics for Aerospace

While ISO 9000 emphasis was on the COMPLIANCE to the requirements, the focus of AS9100 is on the EFFECTIVENESS of the Quality System.

In order to determine the effectiveness of a system, one must be able to measure the inputs and outputs of the system.

Psychology of Metrics

  • Results Based
  • Clear Objectives
  • Process and Product Focus
  • Focus on Numbers
  • Avoid Misuse

Quality Metrics for Aerospace

The metrics matrix will be a value added tool of measurements from the top-level business process through design and engineering, into the manufacturing of products and installation and testing.

Example-Quality Metrics Tree

Level One Quality Metrics identify top level measurables- for example:

1. Customer satisfaction rating on cost, timeliness, accuracy, or other key characteristics

2. Number of outputs for which customer requirements have been identified and defined

3. Number of customer complaints

4. Number of waivers to procedures per day/week/month

Processing

Using Manufacturing as the Level One Process, the identified Level Two Process Metrics could include the following:

1. Percent reduction of elapsed process time (process time now vs. process time before)

2. Percent increase in flexibility (response time now vs. response time before)

3. Percent reduction of cost required to complete process (cost now vs. cost before)

4. Percent increase in accuracy (number of defect now vs. number of defects before)

5. Percent increase in timeliness (number of on-times now vs. on-time before)

6. Percent reduction in detection/correction costs (cost now vs. cost before)

7. Percent reduction of hands-on time required to complete process (hands-on time now vs. hands-on time before)

Using Manufacturing/Machining as the Level One and Level Two Processes, the identified Level Three Process Metrics could include the following:

1. Percentage of processes for which capability is established

2. Elapsed time vs. hands on time

3. Amount of hands on time (in hours) devoted to non-value added steps in:

·        Inspection, Rework, Duplicate approvals

4. Cost of non-value added steps (hands on time x costing rate)

5. Number of defects or errors in output (per hour/day/week/per unit/page/form)

6. Number of on-time deliveries (per schedule, contract, or promise date)

7. Cost of quality (cost of prevention activities + cost of detection/correction activities)

8. Machine Capability Studies

Quality Metrics for Aerospace

The Quality Metrics initiative is to develop and implement a set of standardized metrics across the various NASA centers and laboratories. The development of a web based quality metrics matrix will allow for customers and suppliers to select the value added metrics for all areas of business.

Quality Metrics for Aerospace

The Quality Metrics Initiative is a JPL coordinated, NASA (soon to be sponsored) activity that will involve all NASA Centers and various Aerospace Companies in the development

Keys for Success

  • Understand the purpose of metrics
  • Focus on results
  • Objective measures
  • Knowledge acceptance and transfer
  • Clear, relevant metrics
