Please Don't Take My Subjectivity Away!

"Does it make the decision for me?"
That's a question that somebody asked me again last week, and it is a question that I hear often from people when I tell them about our software. Underneath this question there is an unspoken worry that using a decision analysis tool will somehow override their often very good subjective decision-making ability and authority. I answer it by explaining that it is something like the difference between digging a basement for a house with a hand shovel or a using back-hoe: you still get to choose where and how the basement is dug (the most important subjective decision), but the back-hoe will give you a much faster and better result.
In other words, a good decision analysis tool will enhance and support your subjective judgment by giving you a wider and more focused view of your alternatives.
Decision analysts like to say that they help people make "more objective decisions." This is true if the methodology is sound. (By the way, that is a big "if." Lousy methodology can make things worse.) But in complex and unique business decisions, objective analysis doesn't mean that you can just feed in some numbers and out pops the perfect answer. Instead, a good decision analysis tool will move the subjective analysis to a higher and more strategic level of the decision-making process while leaving the objective number-crunching to the application.
In project portfolio analysis, even using sophisticated tools like Optsee®, there is still a lot of subjectivity that enters into the analysis. For example, there's project risk assessment, budget estimates, and NPV valuations, just to name a few. Then there's assigning weights to the criteria so the project ranking reflects your company's strategy. Finally, there is trying different budget and optimization strategies to select a portfolio that brings you the highest value based on your project set, budget and resource constraints, and business goals.
How is this more or less subjective than doing it manually?
Using spreadsheets or labor-intensive "one model at a time" analyses bog you down in a very low tactical level of subjectively trying to find an optimal portfolio, one project at a time, from billions of possible portfolios. And when you're doing it as a team, this process can quickly become tedious and non-strategic as discussions focus on arguing over the subjective criteria of including or excluding individual projects while losing sight of the big picture.
In other words, when you're at the bottom of a basement digging with a shovel, it is hard to see what the whole thing looks like from the top.
With a portfolio and budgeting analysis tool like Optsee®, you move way up the strategic scale, from picking projects to build a portfolio to picking an optimized portfolio from a few already-optimized alternatives. The "objective" parts – ranking the projects based on value and optimizing against different combinations of business constraints – has already been done for you. So you get to focus your time, energy, and judgment on the most important strategic question – how you can allocate you company's resources to get the highest return from your portfolio.
Like using a back-hoe instead of a hand shovel to dig a basement, using software that moves you up from just making tactical decisions to making more strategic decisions makes sense. But are there places in your company where you're still digging basements with shovels?
