Even the best analyst will be much better using more advanced tools: They are more productive, make fewer mistakes, and can maintain their work with less effort and more understandably. More advanced tools makes the work more repeatable.
But it’s not just about tools, it’s about skills. Excel and the risk extensions to it allow anyone to start applying risk to their estimates. But that doesn’t mean the results are worth anything. It all depends on the quality of the analyst driving those tools. You need an analyst that understands the process and the methodology, and through meticulous work, they can produce great results with any tool. The difference is how hard they have to work to get there.
A good analogy is a carpenter. A master carpenter can make great furniture with just a saw and a hammer. And an apprentice can definitely produce furniture with the same tools – just not of the same quality. But put a master carpenter in a fully-equipped woodshop, and not only can he make great furniture, but he can do so rapidly, and repeatably.
If you have great carpenter on staff, all you need to do is equip the shop. You don’t need us.
But you don’t hire a carpenter if you just want one table or even ten. Hire us to make the tables for you.
