Appendix A of Part 0 contains notes on the notation used. The following should be noted with respect to the
14、terms “phase“ and “activity“: In the descrip-tion of the phase diagrams, the term “phase“ is used throughout to refer to the processing steps; in the descriptions of the activity diagrams, the term “activity“ is used throughout. For each of the phases described in detail, there is either one activit
15、y which has the same name, or the phase comprises a number of activities. Similarly, the milestones used in the phase diagrams have corresponding states in the activity diagrams. 2.2 Overview of the ECR Reference Process The purpose of the phase will first be described, followed by an overview of ea
16、ch phase. This is then followed by more detailed descriptions of the activities in the course of the normal flow and of special flow variants and exceptions (cancellation, fast-track execution, rollback). 2.2.1 Purpose The objective of the ECR Refernece Process is to determine the extent and impact
17、of the planned change, its feasibility (with regard to design, manufacturing), affected persons or departments, affected parts/documents, the collection of comments and assessments by ex-perts concerning costs, dates, quality, weight, preparation time, and others, and finally the decision to accept
18、or reject the planned change. 2.2.2 Phases of the ECR Reference Process In the context of the overall ECM Reference Process the Specification and Decision on Change phase begins after milestone M3, Potential Solution Defined, has been reached. It starts with the Inquiry of ECR phase, in which a prop
19、osal for a change is received and checked to see whether it will be pursued (see Figure 1). If the change proposal is to be pur-sued further, milestone M3.1, ECR Initiated, is reached and the proposal for a change is cre-ated as a change request in the Creation of ECR phase and is prepared for furth
20、er evalua-tion.

After finishing the analysis milestone M3.3, ECR Detailed, is reached and the ECR is evaluated from the point of view of other specialist departments in the Commen
22、ting on ECR phase. After finishing commenting milestone M3.4 ECR Commented, is reached, and a deci-sion is made with respect to the ECR in the Approval of ECR phase.

23、: Version 1.0 5 the Specification and Decision on Change phase ends and milestone M4, ECR Approved, of the overall ECM Reference Process is reached. 2.2.3 Normal flow and status The ECR Reference Process starts with the status pending when a proposal for an ECR is received from one of the possible i
24、nitiators of an ECR in the activity Inquiry of ECR (see Fig-ure 2). The proposal for an ECR may be accepted or rejected (documented in ACCEPTANCE.decision as shown). In the case of rejection, the ECR Reference Process is terminated with the status disapproved (documented in the value STATUS.status),
25、 otherwise the intermediate status initiated is reached. This is followed by the activity Creation of ECR, in which the regular change request is created, described in more detail and prepared for the subsequent steps. This results in a decision on whether the ECR is accepted or rejected for further
26、 detailing, commenting and approval. If the ECR is rejected, the ECR activity is again terminated in the status disapproved; otherwise the intermediate status created is reached. Creation of ECR is followed by the activity Technical Analysis of ECR, in which the technical aspects and the impact of t
27、he potential change are examined in greater detail and evaluated. In particular, the scope of the change is determined with respect to the parts/documents affected etc. Once the change request has been described in detail, the intermediate status detailed is reached and the activity Commenting on EC
28、R follows, in which the change request is evaluated from other points of view. Once this activity is completed, the intermediate status commented is reached, and the ECR is prepared for the activity Approval of ECR, in which the change re-quest is finally accepted for implementation and the process
29、reaches the status approved. Alternatively, the ECR can ultimately be rejected, in which case the status disapproved is again reached. The individual activities are described in more detail in section 2.4. From the time the activity Technical Analysis of ECR starts until the time the activity Com-me
30、nting on ECR ends, the list of those involved in the ECR Reference Process can be changed (several times if necessary) by carrying out the optional activity Modify Distribution List. Depending on the results of the activities Technical Analysis of ECR or Commenting on ECR, participants can be added,
31、 for example to process analyses or make comments, or removed because they are not affected by the change.

43、 planned change no longer ap-pears to have sufficient potential benefit during the course of the process, for example as a result of outlay or deadline considerations. In this case, persons on the Distribution List can be notified of this by means of the Notify_ECR_canceled message (see Figure 6). R

45、ormal process with the objective of reducing the throughput time of the ECR or of implementing the change earlier than usual. The following types of fast-track execution are recommended: 1. Fast run: This variant does not involve a special process; those responsible for performing the activities sim
46、ply execute them more quickly than in the normal process. This variant is indicated by a CLASS instance with CLASS.id = fast run referenced by HEADER.change_process_type. 2. Estimation-based approval: With the “estimation-based approval“ variant, it is laid down in the first three activities (Inquir
47、y of ECR, Creation of ECR or Technical Analysis of ECR) that the decision regarding the ECR will be taken on the basis of the estimated value as specified in the activity Technical Analysis of ECR and that review-evaluation comments during the activity Commenting on ECR (see 2.4.4) will be skipped.
48、In this case, only technical comments etc. are exchanged during Commenting on ECR. Estimation-based approval can be selected if, in the opinion of the EC Manager, the estimated evaluation of the ECR from the activity Technical Analysis of ECR is adequate or if time constraints ne-cessitate a shorter
49、 throughput time for the ECR. This variant is indicated by a CLASS instance with CLASS.id = estimation based approval referenced by HEADER.change_process_type.
