This is term that is used to describe how much effort the company is willing to put into solving a problem. It regards commitment as a very important condition for success. This is an important concept to understand.
Management Resolve is not leadership, or ability, two other things you need to be successful. Being committed is not the same as being able to. Many people are committed to being a major league baseball pitcher, few actually can do it. And there are many other factors that affect success that may be far more important.
Story time:
At the beginning of my career, as the Colonial system was falling out of favor, some military contractors still held that Management Resolve was the only way to a successful project. They found out the hard way that things were changing.
During a discussion with one subcontractor while we were developing a proposal, I kept returning to the performance reasons why our equipment would win. The subcontractor finally laughed and said that contracts weren't awarded based on equipment performance or cost. I was a little surprised, and I asked what were they awarded based on?
"Management Resolve".
I was speechless. I had never heard those words put together. And I certainly didn't know how to write a proposal that emphasized this.
I believe that what she meant is that the personal relationship you establish with the prime is more important than any technical approach. They regarded the technical part as "tinker toys", something that could be done by anyone with enough "Management Resolve". Not a great flag when they were supplying the most technically challenging part of the design. So we elected not to use this subcontractor.
Coincidentally, or perhaps not, so did all other bidders. No one bid using that subcontractor. Everyone bidding found the contractor unqualified. So the contract was not awarded. That subcontractor was picked by Grumman to produce the equipment directly. This particular piece of equipment was never functional, never fielded. That company went under, in spite of their resolve. The lesson is that resolve is part of the equation, and may win you the proposal, but is not the entire answer. Eventually, something has to work well enough to suit the purpose.
This is why people selected Microsoft operating systems and applications, or IBM. Even though the actual products they provided were not top of the line at the point of introduction (Windows 95 was referred to as Mac 89 in our shop). Purchasers believed that Microsoft, IBM, Sun, etc. would keep at it, and eventually produce a good product. Management Resolve.
Management Resolve is a part of launching a product. Sometimes it may be very important. But it is only one of several factors that must be addressed in product development. For an in depth discussion of this, look here: How to Launch a Product
