The IT strategy development logic is the following:
Business strategy -> business architecture TO-BE -> application + information architectures TO-BE -> technical architecture TO-BE -> IT (or EA) AS-IS -> IT roadmap
Main topics in the IT strategy document are the following:
- Executive summary (½ page – summary for senior management, e.g. the Board members)
- Business context (½ page – WHY the major directions in the IT strategy have been taken)
- Strategic directions for the IT as an enabler for the company’s mission and vision
- Potentials of the IT as a strategic driver for the company’s business
- IT contribution to business success (1 page - HOW IT capabilities and plans will contribute value to the business or delta in business is reflected by the delta in IT)
- IT guiding principles (½ page – rationales to guide IT decision making)
- Assessment of the current state of the IT environment
- IT Roadmap (WHEN and WHAT to reinforce and build)

And the final advise: be careful with arrows - people may interpret them differently.
