5.4.2 Release Control and Engineering Change Control

Intended learning outcomes: Describe release and engineering change control (ECC), particularly step-wise release. Present procedures in engineering for new product design or a new product release.


Release and engineering change control (ECC) is an organizational concept for the process of the design and manufacture of a new product or of a new release of an existing product.

Release control and engineering change control (ECC) coordinate the pro­duc­tion or modifi­cation of all blueprints, bills of material, routing sheets, and all other common documentation on a product and its manufacture. The procedure is project oriented and step-wise releases new develop­ments, or changes to existing products, to production. Project management of this kind includes the following tasks:

  • Coordination of development and design: Planning the volume of the release, labeling of all items; stopping the use of these items for planning & control; request for change or new concept of products; quality control; design release of individual items; design release of all items belonging to the volume of the release.
  • Procedures for production release: Transfer of bills of material and routing sheets; release of all items belonging to the volume of the release.

Step-wise release is particularly important to provide for the principle of simultaneous engineering (see Figure 5.4.1.3). For this reason, we often distinguish between:

  • Rough-cut release for the production of a new development project or a new release: The data released base upon preliminary drawings. They are provisional and pertain only to the most important products and rough-cut bills of material and routing sheets. They include the most important components that allow activation of the procurement and production process at lower design-structu­re levels. Depending on work progress, several rough-cut releases are conceivable.
  • Detailed production release with detailed documents: Project management of the new release ensures that all required documents, such as blueprints, bills of material, routing sheets, and numerical control programs, are available in detailed form. Pro­ject management then releases individual items, or all items, to detailed production.

This kind of step-wise release corresponds to common practices in planning & control, which works with various temporal ranges of planning and rough-cut or detailed structures.

Figure 5.4.2.1 presents the different tasks and phases that must be handled by the (systems) engineering (see Section 19.1) for a new product or a new release of a product.

Preliminary study and main study can result in provisional releases, while detailed study leads to final release.
