Management Role(s)
The portfolio management model actually forces a true bridging and integration between IT and the business. Costs, business benefits, technical performance, and capital creation (tangible and intangible) are managed within one framework and require joint participation.
All stakeholders - from programmers and project managers to business and IT managers - have the role of managing some aspect of the investment portfolio. And, in totality, the organization's IT investment is really being managed as a business investment.
The enterprise CIO may be the overall "fund manager" working to assist in the diversification and management of investments across lines of business.
LOB CIOs and IT department heads can be viewed as "portfolio managers" with the goal of maximizing the cost/benefit performance of the systems, services, or technology under their control.
The project origination process is fluid. Proposals from the business and from those in IT with stewardship for results maximization bear equal weight. The project funding process, whether for a new project or renewal of an existing asset, is a joint one.
Overall, the common thread within this model is "value." Whether value is tangible or intangible, and whether it is expressed in terms of dollars or quality of life, value is what information technology for the next millennium is all about.
