Good article. To summarise:

1. Be clear on the functional requirements - business, people, users, etc;
2. Lowest Common Denominators - ICT enabling infrastructure sufficiently scaleable to address the functional requirements;
3. How do you eat the elephant? A bite at a time - chunk the larger project or outcome requirement into smaller achievable results/projects. Smaller, agile components that enable "runs on the board" and build confidence an overall success.
