Actor Performance Analysis

(Deze informatie is alleen beschikbaar in het Engels)   

The Actor Performances Analysis (APA) aims to provide a method that supports the LCM team by specifying the baseline data applicable for controlling the cost and system effectiveness.
The objective is to achieve a quantitative Logistics Program by means of planning and specifying all the necessary products, processes, actors, resources and budgets, based on the Analysis results.

Based on the logistics process breakdown structure (refer figure 4-3) the PRODUCT, ACTIVITY and ACTOR entities can be related to an INSTALLATION and programmed per Status Category as illustrated in next figure.


The Logistics Program illustrated as an imaginary card-tray.

From an LCM point of view this method of programming implies that the activities are the basic entities to manage and control. The activities should be the originating factors of programming. Only with effective and well-planned activities can a system become operational and be kept up and running.

Based on this reasoning the Activity Based Costing method is used as basis for the development of a practical 'basic activity block' and clear procedures (rules of the game). The results have been evaluated as a practical and well-accepted approach.

The Basic Activity Block.

The layout of the basic activity block is based on the following philosophy.

Terms and resources are considered as essential inputs for product-producing activities. The following conclusions are drawn:

  • Well-specified terms (requirements) are necessary to obtain the required products;
  • Performing an activity requires resources which involve /cause costs, even when no (useful) products are delivered.

Control is considered as a management or engineering product (e.g. norms, project plans, test plans, inspection procedures, etc.). The necessity of control activities depends on the terms and level of actor competence.

Support is considered as helpful and efficient to use but not essential. Its necessity depends on the situation and/or the need of the client-actor. For example support activities for the prime activity 'gearbox production' could well be management information, calibration, performance measurement, administration, etc.

To integrate the basic activity block into LCM-systems, a study has been performed to develop a generic technique to set up logistic programs that can be adjusted to various Year-Periods. Experience has shown that filling in the logistics process breakdown structure in order to achieve detailed quantitative logistic data from the actors, represented by the (first line) management, requires some simplifications. The first simplification is to combine the product-activity-actor chain in one element, named PRODUCT/ACTOR block.

This is possible because it is recognized that the product-activity-actor chain represents a unique combination in the logistics process over the life cycle of an asset. Moreover the activity (the way 'how' products are realized) is considered to be the prime actor's responsibility and therefore of less interest for overall asset management. These simplifications result in product/actor chains as illustrated in the next figure.

The Product/Actor (Process) Chain.

This approach makes it possible to define product/actor chains per INSTALLATION and defines 'who' is responsible, 'when', and for 'what'. In this context it is expected that each actor professionally accomplishes his activities according to contract management principles.
