Let me demonstrate how it's not that easy. This is the short list
- Investigate Requirements
- Comply with Corporate Governance
- Ensure there's a budget to buy 400,000 computers, and 400,000 copies of new software
- Ensure there's a budget to have manpower to deploy new systems
- Getting upper management to sign off to replace computers
- Investigating, Mitigating, and Eliminating Incompatibility issues with Existing Information Systems
- Ensure computers meet new safety regulations and laws
- Ensure new computers meet federal, state and local privacy laws as well as any international laws (EU Laws)you may have to observe because you have a customer in a different country
- Physical and Logical Security Measures need to be developed, analyzed and tested
- Business Continuity Plans need to be updated and tested
- Disaster Recovery Plans need to be updated and tested
- Deployment and Configuration of 400,000 Computers
- Transferring Data from old computers to new computers so the transition is seamless
- What to do with old computers
- How to properly dispose of computers. (Immediately giving them away to charity or to a local school is out of the question as you still need to WIPE the hard drive clean completely and properly, especially if there's sensitive, if not confidential information on the hard drive)
Each item I've listed itself is a ton of work. They branch in so many different directions you never know what you will find.
