Dataflow Management is an operating practice, founded in 1998 and run by its principal, Tom Marsh, as his full-time work since 2002. Clients embed him inside their organizations, usually for years at a time, to plan and then run the physical and technical footprint: the real estate and facilities, the multi-year capital program, the data centers and critical power, and the networks that tie them together. It covers two disciplines that most firms keep apart, the technology that runs an organization and the real estate and facilities that carry it, because in a critical environment they hold or fall together.
That is a different arrangement than advice. The longest engagement ran twenty-two and a half years at one institution, renewed annually, reporting first to the CEO and then to the CIO. Spend moves on his authority. He writes the service levels, including chronic-failure termination rights, and he enforces them. He has built and led mixed teams of up to 350 people, union and non-union, internal and contracted, across four regions.
The judgment comes from operating. We hold no vendor relationships, take no commissions, and resell nothing, so the only interest in the room is the client's.
Our clients include firms in technology, life sciences, higher education and research, manufacturing, insurance, law, construction, and private equity. The people who bring us in are usually CFOs, CIOs, COOs, and the heads of real estate, workplace, or operations who answer for the result. We do not name them, because confidentiality is part of what they are buying.
