Microsoft Solutions Framework...
Planning IT strategy is a daunting task at best. It is the intersection of business needs, strategies and technology. It's also the intersection between all of the stakeholders in an organization. Technology choices well made can improve efficiency and profitability; the reverse is also true. Over the years Microsoft has developed a proven method for successful integration of technology in any organization.
Once a plan has been followed through, all plans will eventually either need adjustment or re-design. All technology has a life cycle so ideally it's a constant process that maximizes worker's productivity.
The Microsoft Operations Framework, (MOF), is no different. It's continuously updated by Microsoft and updated to meet with thier latest research. Currently the latest is version 4.0.
