Will changing project staff or a key resignation disrupt our project?
Project membership cannot be guaranteed never to change. Wavesteam should keep the project lead and core technical roles stable where practical, and should not rotate key people repeatedly without explaining the change and its impact.
The project must not depend on one person's memory. Requirements and decisions, design, code, interfaces, deployment procedures, and issue history belong in a shared project space. Code receives peer review, and critical environments and accounts are controlled by the client or by multiple designated custodians rather than one employee.
When turning a business goal into an executable scope, also compare Who operates the system after launch if we have no technical staff? and Should a small project hire a specialist team or a large software company?; the linked guidance adds context that should be considered in the same decision.
When a change is necessary, the client should receive the reason, replacement role, availability, and expected impact in advance where circumstances allow. Handover includes a document audit, code and architecture walkthrough, open decisions, unfinished work, environment access, operational risks, and a period of overlap appropriate to the role. Another qualified team member should verify the transfer instead of relying only on the departing person's assurance.
The contract can name key roles, notification requirements, a handover checklist, replacement qualification, and responsibility for resulting delay. The client should continuously retain access to repositories, documentation, deployments, monitoring, and core accounts. That makes staff movement a managed continuity event rather than a loss of control over the system.
