What does ROM stand for in project management?

Rough Order of Magnitude (ROM) Costs and Detailed Cost Estimates.

What is ROM in estimating?

There are essentially two ways to estimate the cost of a project. One of the most commonly used techniques is the ROM estimate or Rough Order of Magnitude estimate. Another way to estimate the cost of a project is by using a definitive estimate.

How do you calculate ROM estimate?

Upper Boundary = ROM_Estimate x (1 + 75\%) = ROM_Estimate x 1.75; Lower Boundary = ROM_Estimate x (1 – 25\%) = ROM_Estimate x 0.75. In practice, the more challenging part is usually to come up with the ROM estimate (i.e. the basis for the ROM range) rather than calculating the boundaries of that range.

What is the purpose of the rough order of magnitude cost estimate?

A rough order of magnitude estimate is used to give you a very high level view of potential project costs. Ideally, you’d be able to provide a definitive estimate, carefully created from loads of input from subject matter experts and plenty of research on past projects and their budgets.

What is high level ROM?

In other words, this high level estimate lets you know whether the project is going to take $50,000 or $5,000,000. Whether it will take six weeks, six months, or six years. According to A Guide to the Project Management Body of Knowledge (PMBOK® Guide), a ROM estimate typically varies from −25\% to +75\%.

What is the purpose of the ROM?

ROM is memory that cannot be changed by a program or user. ROM retains its memory even after the computer is turned off. For example, ROM stores the instructions for the computer to start up when it is turned on again.

What is ROM proposal?

A Rough Order of Magnitude Estimate (ROM estimate) is an estimation of a project’s level of effort and cost to complete. The point is to provide a “ballpark” estimate using the information available at the time. A ROM estimate’s variance is rather large, but it should not disuade you from making an attempt.

How much does ROM cost?

Finally, a PC Card and PCMCIA CD-ROM Drive usually cost between $100-$300 again due to having an advantage of better speed, faster interface accompanied by a huge capacity in most case. Thus, a good ROM generally costs around somewhere between $100-$300.
