Software Handover Checklist: Access, Runbooks and Ownership

Identifiez l'équipe qui reçoit.

Demandez qui exploitera, maintiendra et approuvera les modifications apportées à l'application après la livraison. Il peut s'agir de personnes différentes. Confirmez les informations dont chaque personne a besoin, depuis les instructions d'utilisation quotidiennes jusqu'aux procédures de déploiement. Évitez de supposer que les connaissances d’un développeur seront transférées automatiquement via une démonstration.

Parcourez des tâches opérationnelles réelles.

Utilisez un environnement contrôlé pour répéter les tâches de support de routine, accéder aux modifications et à une version. Enregistrez les dépendances et la voie à suivre pour l’escalade. La documentation doit aider l'équipe de réception à répéter une action, y compris comment vérifier qu'elle a fonctionné et que faire en cas d'échec d'une étape attendue.

Combler les écarts de propriété.

Confirmez où le code source, les instructions de configuration et les enregistrements de support sont stockés. Transférez l’accès via des canaux approuvés plutôt que d’intégrer les informations d’identification dans les documents. Terminez par une liste convenue des problèmes en suspens et des propriétaires responsables afin que la fin de la livraison ne laisse pas de décisions essentielles sans solution.

Test the handover with the receiving team

List the tasks the receiving team must perform after delivery: deploy a change, configure the application, investigate a failure and find the right escalation owner. Prepare instructions for those tasks, then ask someone who did not write them to follow the steps in a suitable environment.

Record missing prerequisites, unclear commands and undocumented decisions. Check that repositories, environments and third-party services have appropriate organizational ownership. Transfer access through approved processes and confirm that obsolete project access is reviewed. Finish by agreeing acceptance evidence and the boundaries of any post-delivery support. A document being sent is not the same as a team being ready to operate the software.

A handover pack people can use

Organize the pack around tasks rather than a large unstructured folder. Keep links current and name the owner who maintains each part.

• Application overview: main workflows, components, dependencies and important design decisions.
• Setup and deployment: prerequisites, configuration names, environment differences and verification steps.
• Operational runbook: health checks, common failures, recovery guidance and escalation contacts.
• Data responsibilities: storage locations, access ownership and agreed backup or restoration procedures.
• Delivery evidence: test results, known issues, accepted limitations and outstanding work.
• Ownership record: repositories, third-party accounts, documentation updates and support boundaries.

Keep secrets out of the handover document

Document where configuration is supplied and who manages it, rather than embedding live passwords or tokens in a shared guide. A readable runbook should still be usable when a credential is rotated.

Avoid assigning support to “the development team” without naming the receiving role and the arrangement. Clarify response expectations, covered systems and exclusions. Keep known issues visible; hiding them in an old conversation creates uncertainty for the people taking responsibility.

When should handover preparation begin?

Start while the system is being built, especially for deployment and operational decisions. Update the pack as the implementation changes. Schedule a receiving-team walkthrough before final acceptance so missing information can be corrected while the delivery team is still available.

ILLUSTRATIVE PLANNING EXAMPLE

Example: handing over a web application

Ask the receiving team to deploy the application in a suitable test environment using the handover instructions. Check that they can locate configuration guidance, run agreed checks and identify the person responsible for an incident. Transfer credentials through an approved secure channel rather than placing them in a document or email.

Record missing instructions and resolve them before sign-off. Agree which support tasks are included after handover and which need a separate arrangement.
