Problem solving — or sometimes even just stating the problem — usually entails discovery. After successful resolution, we can look back at our path, and we usually notice new techniques, new concepts and new perspectives. For difficult problems, the path includes several failed attempts, which perhaps we used to refine either the problem statement or our approach or both. Or we decide to solve a simpler problem first, and use that experience to re-examine the original problem. Or we decide that we can't solve the original problem, but we do address the parts that seem tractable.
These latter approaches are all elements of the incremental problem-solving toolkit. Often, incremental problem solving produces useful results, but there is a risk that the results produced aren't optimal by any measure (see, for example, "Indicators of Lock-In: I," Point Lookout for March 23, 2011). And a string of promising results might lead not to the ultimate objective, but to a dead end.
That's why backtracking is so important in the incremental toolkit, but it can be difficult or impossible to use. Why?
Typically, increments produce useful capability, while they illuminate possible next steps. When customers use the capability so far delivered, more wants and needs become clear. All these lessons together help determine objectives for future increments. So it goes, iteration by iteration.
Although the solving helps illuminate the path, that path might or might not lead to the final objective. When it doesn't, we must backtrack, and therein lies risk. Here are some obstacles to backtracking in incremental problem solving.
- Blindness
- Once a particular approach is embedded in the consciousness, seeing new approaches can become difficult, even when we're looking for them.
- Sunk cost
- Whatever we've spent so far can sometimes prevent us from trying new approaches. We might lack the resources or time to rebuild what we've done, or we might lack the daring to ask for what we need.
- Seeing backtracking as failure
- Whether or not we have time or resources for backtracking, organizational culture might prohibit it. We push ahead because backtracking feels like failure, even when it's the only path to success.
- Short term cost bump
- Immediately after backtracking, the cost per unit of delivered capability jumps, because cost has risen, while capability hasn't. Capability might even decline. To some, that can seem more important than enabling future success.
- Backtracking costs real money
- Backtracking takes time and effort. Even when the cost is small,
the short-term return on
backtracking is negativeEven when the cost is small, short-term return is negative. We're paying to go backwards. - Customer expectations
- Sometimes backtracking upsets customers, who have become accustomed to a steady stream of forward progress. It can be difficult to explain the need to redevelop something customers are already happy with.
With astonishing frequency, when we pause and ask, "How would we do this if we were starting over, knowing what we now know?" the answer is both novel and elegant. When we can find the resources and the will to backtrack enough to use what we've learned, our solutions are more durable, more effective and longer-lived. Top Next Issue

- Bois Sec!
- When your current approach isn't working, you can scrap whatever you're doing and start again —
if you have enough time and money. There's a less radical solution, and if it works, it's usually both
cheaper and faster.
- Forward Backtracking
- The nastiest part about solving complex problems isn't their complexity. It's the feeling of being overwhelmed
when we realize we haven't a clue about how to get from where we are to where we need to be. Here's
one way to get a clue.
- Playing at Work
- Eight hours a day — usually more — of meetings, phone calls, reading and writing email and
text messages, briefing others or being briefed, is enough to drive anyone around the bend. To re-energize,
to clarify one's perspective, and to restore creative capacity, play is essential. Play at work, I mean.
- Remote Hires: Inquiry
- When knowledge workers join organizations as remote hires, they must learn what's expected of them and
how it fits with what everyone else is doing. This can be difficult when everyone is remote. A systematic
knowledge-based inquiry procedure can help.
- Disproof of Concept
- Proof-of-concept studies of system designs usually try to devise solution options and discover the system's
operating constraints. But limitations can become clear too late. A different approach — disproof
of concept — can be a useful alternative.
