流程目的(Process Purpose)

The purpose of the Change Request Management Process is to ensure that change requests are managed, tracked and implemented.

變更請求管理流程的目的是為確保變更請求被管理、追蹤和實作。

流程結果(Process Outcome)

成功實作建構管理流程,其相應的結果如下:

[Outcome 1]制定一個變更請求管理策略;
[Outcome 2]識別與紀錄變更請求;
[Outcome 3]識別與其他變更請求的相依性與關係;
[Outcome 4]定義確認變更請求實作的條件;
[Outcome 5]分析變更請求,並預估其所需資源;
[Outcome 6]根據分析結果與可用資源,核准並排序變更
[Outcome 7]實作並追蹤被核准的變更直至其結案
[Outcome 8]所有變更請求的狀態是已知的
[Outcome 9]建立變更請求與被影響的工作產出間的雙向追溯

基礎實踐(Base Practices)

SUP.10.BP1: Develop a change request management strategy.
SUP.10.BP1: 制定一個變更請求管理策略
[Outcome 1]

Develop a change request management strategy, including change request activities, a status model for the change requests, analysis criteria, and responsibilities for performing these activities. Interfaces to affected parties are defined and maintained.

制定一個變更請求管理策略,包含變更請求活動、變更請求狀態模型、分析準則(標準)、執行變更請求活動的人員與責任。定義和維護(變更)影響方的介面。

NOTE 1: A status model for change requests may contain: open, under investigation, approved for implementation, allocated, implemented, fixed, closed, etc.
NOTE 2: Typical analysis criteria are: resource requirements, scheduling issues, risks, benefits, etc.
NOTE 3: Change request activities ensure that change requests are systematically identified, described, recorded, analyzed, implemented, and managed.
NOTE 4: The change request management strategy may cover different proceedings across the product life cycle, e.g. during prototype construction and series development.

備註1: 變更請求的狀態模型可包含:開放、調查中、已核准實作、已分派、已實作、已修正、已關閉、等。
備註2: 典型的分析準則(標準)有:資源需求、計劃問題、風險、收益等。
備註3: 變更請求活動是為了確保變更請求可以被系統地識別、描述、記錄、分析、實施和管理。
備註4: 變更請求管理策略可涵蓋整個產品生命週期中的不同程序,例如在原型製作和系列(產品)開發。

變更請求參考狀態模型

SUP.10.BP2: Identify and record the change requests.
SUP.10.BP2: 識別與紀錄變更請求
[Outcome 2,3]

Each change request is uniquely identified, described, and recorded according to the strategy, including the initiator and reason of the change request.

每一個變更請求均根據策略進行唯一識別、描述和紀錄。需被識別、描述和紀錄的資訊包含:變更發起者和變更請求的原因。

SUP.10.BP3: Record the status of change requests.
SUP.10.BP3: 紀錄變更請求的狀態
[Outcome 8]

A status according to the status model is assigned to each change request to facilitate tracking.

根據所定義的狀態模型,針對每個變更請求的設定狀態,以方便於追蹤。

SUP.10.BP4: Analyze and assess change requests.
SUP.10.BP4: 分析且評估變更請求
[Outcome 3,4,5,9]

Change requests are analyzed according to the strategy including their dependencies to affected work products and other change requests. Assess the impact of the change requests and establish criteria for confirming implementation.

根據BP1所制定的策略分析變更請求,包含其對受影響的工作產出的關聯性,以及其他變更請求。評估變更請求的影響,並建立變更實作後的允收標準。

SUP.10.BP5: Approve change requests before implementation.
SUP.10.BP5: 在實作前核准變更請求
[Outcome 6]

Change requests are prioritized based on analysis results and availability of resources before implementation and approved according to the strategy.

在實作變更前,應根據分析結果和資源可用性,排定變更請求的優先順序。

NOTE 5: A Change Control Board (CCB) is a common mechanism used to approve change requests.
NOTE 6: Prioritization of change requests may be done by allocation to releases.

備註5: 變更控制委員會是核准變更請求的常見機制
備註6: 變更請求的優先順序可透過發配到不同的發布來完成

SUP.10.BP6: Review the implementation of change requests.
SUP.10.BP6: 審查變更請求的實作成果
[Outcome 7,8]

The implementation of change requests is reviewed before closure to ensure that their criteria for confirming implementation are satisfied, and that all relevant processes have been applied.

變更請求在實作結束前應進行審查,以確保(1)變更實作滿足BP4所制定的允收標準,(2)所有相關流程均已被採用。

SUP.10.BP7: Track change requests to closure.
SUP.10.BP7: 追蹤變更請求直到其結案
[Outcome 7,8]

Change requests are tracked until closure. Feedback to the initiator is provided.

追蹤變更請求直到其結案並提供反饋給變更發起者。

SUP.10.BP8: Establish bidirectional traceability.
SUP.10.BP8: 建立雙向追溯
[Outcome 9]

Establish bidirectional traceability between change requests and work products affected by the change requests. In case that the change request is initiated by a problem, establish bidirectional traceability between change requests and the corresponding problem reports.

建立變更請求與被變更請求影響的工作產出之間的雙向追溯。如果變更請求是由問題所引發的,則建立變更請求與對應問題報告之間的雙向追溯。

NOTE 7: Bidirectional traceability supports consistency, completeness and impact analysis.

備註7: 雙向追溯性支援覆蓋性、一致性和影響分析。

工作產出(Output Work product)

08–28 變更管理計畫[Outcome 1]
08-04 變更請求 [Outcome 2,3,4,5,6,7]
08–14 審查紀錄 [Outcome 7]
13–08 變更控制紀錄 [Outcome 8,9]
