Assumptions have an unnerving way of becoming facts and received wisdom over time. How do you build some functional assumption-checking into a project team, a process that generates useful feedback and moves the team effort forward?
The only real answer to questions of culture is you hire for it. Culture change is slow, much slower than technological change. This mystifies technocrats, as it should. People are much more challenging and powerful than machines will ever be.
Want more creative teams? Hire creative people. Want more risk taking? Hire for it. No single act defines an organization’s culture more than the people who are hired. If you want to shift a culture the most effective way to do it is to change who you hire.
The reason is simple: people are stubborn. By the time we’re 25 most of our personality traits, desires and habits are well defined and unlikely to change (it’s certainly possible but odds are against it). The primary point of leverage then is who a manager hires (and fires) and why. It’s far easier to hire for traits you need than to try to transform a person who doesn’t have them into someone that does. Even if transformation is the goal, we are social creatures and learn best from the examples around us. The more people in an organization that successfully demonstrate a trait, the easier it is for others to emulate and adopt it.
One great weakness of managers is their arrogant faith in the omnipotence of management. There is the belief, reinforced by management consultants and business books, that simply by decreeing “be innovative” or “work smarter” magic forces that transcend the limits of sociology will transform conservative or stupid people into being otherwise on your behalf. The ability of a manager to achieve something depends heavily on whether the people on staff are even capable of doing that thing. You couldn’t convert the local bakery into a nuclear physics research lab simply by changing the manager or the management philosophy, but that doesn’t stop executives from trying. The current trend of organizations built for decades around core values of conservatism and rule-following magically transforming into entrepreneurial risk taking powerhouses simply because the CEO tells them to is a classic example of this hubris.
My broad ranting aside, to answer the specific question some people are instinctively better at challenging assumptions than others. They ask more questions, have more doubts, and are willing to act on them. I don’t know why they are this way, but I know these people exist. If you want more assumption checking, hire for it. These people are harder to manage since they naturally challenge authority, but if you want assumptions challenged that includes the assumption of hierarchy. Diversity is a natural way to bring more questions into an organization as people with different experiences naturally question each other when they get together to build something. Age difference is one of the most useful kinds of diversity as new graduates and old veterans have many different assumptions, and if healthy debate is encouraged the results will be the best synthesis of those perspectives.
The second part is how you as the manager respond to having your assumptions challenged. If you continually demonstrate that you, the person in charge, is comfortable being challenged, or yielding your idea to a superior one suggested by a colleague or subordinate, everyone who works for you will emulate that behavior. Alternatively if you dismiss challenges, or yell at people who challenge you, the culture of fear your behavior creates will dominate no matter who you hire or how great you proclaim it is to challenge assumptions.
The platitude “there are no sacred cows” is very easy to say, but I’ve rarely heard it said by someone who didn’t really mean “only my sacred cows are sacred.” It takes great confidence as a leader to keep an open mind as the size of their empire grows.
The third part is behaving in ways that separate people from their ideas. Healthy debate is easy if no one is taking the results personally. Most heated debates involve people who have trouble separating their opinions from their identity (the lack of ability to find any humor in a debate is a good sign that someone is taking the issue too seriously). If I draw what turns out to be a lame idea on a whiteboard, in a healthy culture it’s reinforced that the idea is lame, but I’m not. I can still be smart and valuable. Perhaps my lame idea will help lead to a great one. This trust in coworkers is what allows ideas to be debated, attacked, torn down, twisted, reused and improved without any fear of offending anyone. Most successful creative cultures in history were based on this separation. It’s another set of behaviors that leaders must demonstrate regularly. Many talented organizations produce little of merit because of how sensitive people are of criticism, and the fear of offending people or being offended trumps everything else.
There are definitely techniques that encourage the challenge of assumptions but they only work if the above factors are true. My favorites include:
- Postmortem / Debrief: after every project a long conversation should take place where people review what happened, what assumptions were made, what went well and what could have gone better. If lead properly (and witch-hunts and finger pointing are avoided) these conversations are gold. They inject introspection and self-awareness into the culture.
- Experimental attitude: The basic notion of an experiment is you have a hypothesis (which is really a set of assumptions) and you find a way to test it to see if it’s right. Most experiments fail, but the attitude is it’s the only way to learn. Leaders should always be running experiments of some kind with their teams. “Lets try working this way for a week and see what happens.” The continual exposure to the cycle of “assumption, test, learn, repeat” diminishes fear around asking questions and raises everyone’s comfort with making, challenging and testing assumptions.
- Discuss books about thinking: many books address problem solving, question asking, and challenging assumptions, and if read as a team provides a meta-example for exercising what the books try to teach (“e.g. what assumptions in this book about questioning assumptions should we question?) Although it’s more about problem solving, Are Your Lights On? is one my favorites for inspiring people to think more critically, and humorously, about everything.
What do you think? Are there other methods to encourage a culture of questioning assumptions?
