- We are the project manager for an IT project in our company. We identified the following top-level project tasks and estimated durations to standup a small test lab for the project: Identify test lab building/space requirements and possible locations(8days) Select best location for lab (1day) Once the best location is selected, immediately start the next two tasks: Prepare lab space with power and cabling (3days) Identify/procure required specialized test lab hardware/software(5) Once the lab space is prepared, install/check out available infrastructure hardware/software(1day). Once the specialized software/hardware is received and the infrastructure hardware/software is installed/checked out, install/checkout specialized software/hardware (2days) Once all tasks are completed, conduct the final inspection (1 day).
