There is one other minor matter needed to get started (so minor and obvious that I hesitate to even mention it): organizational change management. Yes, one of the most dreaded efforts known to anyone responsible for leading a commercial organization is part and parcel of the significant step IT leaders will need to take to bring their organization to the level necessary to drive innovation in the years ahead.
I say "organizational change management" for two reasons. The first (and most important to me) is that I recently published a book on the subject, making it the right answer no matter what question you might ask -- "How do we get started on the path to SOA?" "How do we get started on a process improvement initiative?" "How do we decide where to have lunch?" "How do biologists account for the existence of the platypus?"
The second and arguably more important reason (to you, at least) is that it's one-third of the answer to the raised objection. The other two-thirds? A design and a project plan. Those are, in fact, needed to achieve any business change.
Your design should be clear about the business objective of the organizational change (revenue, cost, or risk); any new business functions that will be necessary and how they will need to be executed; the existing functions that will have to be modified (and how); and any supporting alterations to your technology set, and to employee roles and skills, needed to achieve the objective.
For the shift we discussed last week, one that moves away from denial-by-default to embrace user initiative, the business objective is to increase revenue and decrease cost by encouraging innovation on the part of all employees.
As for the business functions, tools and technologies, and roles and skills? Beats me. It's your company. The generic answer, suited to the imaginary XYC Corporation beloved of all software developers, includes changes to how the leadership role is defined; how information security is practiced; and a new business function, possibly but not necessarily housed in IT, focused on educating employees on innovation, as well as in the use of development tools suitable for non-IT developers.
Organizational change management means:
