Änderungskontrollprozess in der Softwareentwicklung mit Schritten
⚡ Intelligente Zusammenfassung
Change Control is the formal process a company uses to document, identify, and authorise changes to an IT environment, cutting the risk of unauthorised alterations, disruption, and errors across projects, applications, and infrastructure.
Was ist Änderungskontrolle?
Change Control ist der Prozess, den ein Unternehmen anwendet Änderungen dokumentieren, identifizieren und genehmigen to an IT environment. It reduces the chances of unauthorized alterations, disruption and errors in the system.
Warum Change Control?
Whenever stakeholders request new or different changes to the system, those changes are neither optional nor ignorable. The changes must be implemented without disrupting other components of the system. This is where change control becomes useful. It helps project teams modify project scope using defined controls and policies. Change Control is practiced whenever a project deviates from the plan.
A formal change request document must be completed and reviewed to keep control of every change request.
Common questions raised while analysing a change control request include:
- Wer wird die Änderung genehmigen?
- Does it need to be reviewed by a change control board?
- How much time is required to research and implement the change?
- Welche Auswirkungen haben Änderungen auf andere Komponenten des Systems (Zeitpläne, Kosten, Ressourcen usw.)?
- Is there a threshold below which project management can approve it directly?
Different Factors of the Change Control Process
Es gibt verschiedene Faktoren, die ein Change-Control-Prozess berücksichtigen sollte
| Schritte im Änderungskontrollprozess | In der Änderungskontrolle ergriffene Maßnahme |
|---|---|
| Initiierung und Kontrolle von Änderungsanforderungen | Change requests should be standardised and reviewed by management, and the requestor should be kept informed. |
| Folgenabschätzung | Every change request should be assessed in a structured way to analyse potential impacts. |
| Kontrolle und Dokumentation von Änderungen | A change log should record the date, the person who made the change, and the change itself. Only authorised individuals should be allowed to make changes, and a rollback process should be defined. |
| Dokumentation und Verfahren | Whenever system changes are implemented, the related procedures and documents should be updated to match. |
| Autorisierte Wartung | System access rights should be controlled to prevent unauthorised access. |
| Tests und Benutzerabmeldung | Software should be thoroughly tested, and business users should sign off before release. |
| Versionskontrolle | Production source code should be version controlled so only the latest approved build is deployed. |
| Notfalländerungen | A verbal authorisation should be obtained and the change documented as soon as possible. |
Prozess der Änderungskontrolle
Before diving into the change control process, it is helpful to familiarise ourselves with the documents used in Change Control. Two documents are central to Change Control:
- Änderungsprotokoll: A change log lists details of every Change Request — project number, PCR (Project Change Request) ID, priority, owner, target date, status, status date, raised by, and date raised.
- Antragsformular ändern: It captures the details needed for decision making — type of change, benefits, requestor, time and cost estimate, priority, approver, and change request status.
Change Process Flow Diagram
The change process follows a specific pattern to implement changes in the product or system. The flow diagram below shows the steps involved.
Steps in the Change Control Process
| Schritte zur Änderungskontrolle | Action |
|---|---|
| Identifikation der Änderungsanforderung | Identify the need for a change and describe it on the Project Change Request form. |
| Bewertung des Änderungsantrags | If the change is not valid, defer or reject it. Assign the resources needed to analyse the request, complete a quick impact assessment, and update the change request form. Rejected requests stop at this stage. |
| Analyse von Änderungswünschen | Assign the change request to an authorised member for full analysis. Deferred changes re-enter this step, and rejected requests stop here. |
| Genehmigung der Änderungsanforderung | Identify the risk, complexity, and impact of the change before approval. Route the change request to the authorised approver for a decision. Rejected requests stop at this stage. |
| Implementierung des Änderungsantrags | Update project procedures and management plans, inform the team, monitor progress, record completion, and close the change request. |
HINWEIS: Change Control approval may be granted by the Project Manager, IT Lead or Lead Developer, or a designated Stakeholder.
