Inspection necessity, Supply Chain Management

Inspection Necessity:   

In    case   of   project    management,    planning    and    quality management are necessary processes. However, for quality maintenance and project conformity to all quality standards efficient processes needs to be accomplished. Quality management software is necessary to be applied as a mechanism for quick reaction to occurred errors and discrepancies during the project performance. The necessity to enhance project quality can be achieved as a result of proper working of the software during the project performance. The quality management software allows making quick revision of all project stages and finding errors.

At all variety of possible  kinds  of  project  organisational  structures, observance of following basic principles is necessary:

Advisability:  The general  project  objectives  must  thoroughly  follow  the designed structure.

Cost Effectiveness: The structure shouldn't be excessive, costs for staff increase the project cost, and the project should have certain profit.

Flexibility:  The  project  structure  shouldn't  be  too  rigid.  It  makes  it impossible to react to change in external conditions.

Coordination: The project breakdown into tasks and their assignment to related resources requires accurate collaborative work of the resources.

The acceptability of a lot can vary from no inspection of a sample to 100% inspection which is the decision that needs to be taken by amount of inspection. The decision is governed mainly by the amount of prior knowledge available as to quality, and the allowable degree of risk. Inspection is necessary and a prior knowledge about the quality of product is important in deciding on the amount of inspection.

The amount of inspection includes the following points:

  • Earlier quality history on the product and the supplier.
  • Criticality of the item on overall system performance.
  • Criticality on later manufacturing or service operations.
  • Warranty information or the use history.
  • Measurement of capability information. E.g. availability of accurate and precise instruments.
  • The nature of the manufacturing process. E.g. few operations depend mainly on the adequacy of the setup.
  • Inspection of the first few and the last few items in a production run. This is usually in most of the cases is sufficient.
  • Product homogeneity. E.g. a fluid process is homogeneous and reduces the need for large sample sizes.
  • Data on process variables and process conditions.
  • Degree of adherence to the elements of self-control for the personnel operating the process.

To reduce the amount of inspection, competition involves tough methods to reduce costs and has resulted in pressure. The concept of inspection by the producers (self-inspection) has added to the focus of reducing inspection. Tremendous opportunities exist for cost reduction in inspection activities. At first, however the causes of the high failure costs must be diagnosed and removed, and the prerequisites for self inspection must be met.
