Timing depends on scope and existing systems. A focused review or integration can be short; a new platform is planned in milestones after discovery.
Yes. The first step is a technical review so constraints, ownership, and the safest delivery path are understood before implementation.
Ongoing support can be included as a defined engagement after launch, with scope and response expectations agreed in writing.
