The lesson
Specify by role: office staff need reliable mid-range laptops with SSDs; computer labs need durable, easily managed desktops; field staff need rugged laptops with long battery life.
State minimum specifications, warranty, local support and accessories rather than brand names, so suppliers can compete.
Total cost of ownership includes purchase, power, repairs, support and replacement.
Step by step
- Define three user roles.
- Write minimum specifications.
- Add warranty and support terms.
- Compare total cost of ownership.
Practice activity
Write specifications for an office, a computer lab and field staff.
