Start with the operating picture
List the business workflows that must remain usable: staff applications, calling, meeting rooms, guest access, cameras and operational devices. Identify where each function runs and who can approve its requirements. This does not need to be an enormous document. A concise table of users, devices, locations and owners often exposes missing information before it becomes a design assumption. Keep confirmed requirements separate from expected growth, and explain the basis for any capacity allowance.
Join the physical and logical plans
Switching connects devices within the network, while routing connects networks and their traffic paths. Those functions still depend on the physical installation: room locations, uplinks, outlet records, power and maintenance access. Link the logical topology to rack elevations and cable schedules. A diagram that names a switch but cannot identify its location or uplink is incomplete for field support. Conversely, a beautifully labeled rack does not explain addressing, routing or application dependencies.
Check capacity where it is consumed
A port count does not establish the power budget for cameras, phones or access points. Review supported endpoint requirements and the selected switch capabilities together. Similarly, uplink planning should consider the services sharing that path rather than the nominal speed of one device. Record the assumptions so a future increase in occupancy or camera count can trigger a focused review. Avoid treating every spare port as equivalent available capacity.
Plan the change before the change window
Identify the configurations to back up, the people who can test applications and the conditions that would trigger rollback. A short maintenance window is a poor time to discover that no one has the carrier handoff information. Stage equipment where possible and use a representative pilot when the design is being repeated. The plan should state which checks happen before traffic moves and which must happen with the actual business users afterward.
Make acceptance useful for the next team
Acceptance should connect expected behaviour to observed results. Record link checks, addressing, representative application paths and agreed failure scenarios. Leave unresolved items with an owner and next action. The handover should include editable diagrams, asset identities and configuration references, stored through the customer’s approved process. These records are not an administrative extra: they make the next fault investigation or expansion easier to scope and less dependent on individual memory.
