If you don’t have a problem, you’ve got a big problem.

It’s important to know where a problem happens, but also when it happens.

Solutions are 90% defining and the other half is solving.

To solve a problem, you’ve got to understand things as they are.

Before you start solving a new problem, solve the one you have now.

It’s good to solve your problems, but it’s better to solve you customers’ problems.

Opportunities are problems in sheep’s clothing.

There’s nothing worse than solving the wrong problem – all the cost with none of the solution.

When you’re stumped by a problem, make it worse then do the opposite.

With problem definition, error on the side of clarity.

All problems are business problems, unless you care about society’s problems.

Odds are, your problem has been solved by someone else.  Your real problem is to find them.

Define your problem as narrowly as possible, but no narrower.

Problems are not a sign of weakness.

Before adding something to solve the problem, try removing something.

If your problem involves more than two things, you have more than one problem.

The problem you think you have is never the problem you actually have.

Problems can be solved before, during or after they happen and the solutions are different.

Start with the biggest problem, otherwise you’re only getting ready to solve the biggest problem.

If you can’t draw a closeup sketch of the problem, you don’t understand it well enough.

If you have an itchy backside and you scratch you head, you still have an itch. And it’s the same with problems.

If innovation is all about problem solving and problem solving is all about problem definition, well, there you have it.

In today’s world of continuous improvement, everything is seen as an opportunity for improvement. The good news is things are improving. But the bad news is without governance and good judgement, things can flip from “lots of opportunity for improvement” to “nothing is good enough.”  And when that happens people would rather hang their heads than stick out their necks.

When there’s an improvement goal is propose like this “We’ve got to improve the throughput of process A by 12% over the next three months.” a company that respects their people should want (and expect) responses like these:

As you know, the team is already working to improve processes C, D, and E and we’re behind on those improvement projects. Is improvement of process A more important than the other three? If so, which project do you want to stop so we can start work on process A? If not, can we wait until we finish one of the existing projects before we start a new one?  If not, why are you overloading us when we’re making it clear we already have too much work?

Are we missing customer ship dates on process A? If so, shouldn’t we move resources to process A right now to work off the backlog? If we have no extra resources, let’s authorize some overtime so we can catch up. If not, why is it okay to tolerate late shipments to our customers? Are you saying you want us to do more improvement work AND increase production without overtime?

That’s a pretty specific improvement goal. What are the top three root causes for reduced throughput? Well, if the first part of the improvement is to define the root causes, how do you know we can achieve 12% improvement in 3 months? We learned in our training that Deming said all targets are artificial. Are you trying to impose an artificial improvement target and set us up for failure?

Continuous improvement is infinitely good, but resources are finite.  Like it or not, continuous improvement work WILL be bound by the resources on hand. Might as well ask for continuous improvement work in a way that’s in line with the reality of the team’s capacity.

And one thing to remember for all projects – there’s no partial credit.  When you’re 80% done on ten projects, zero projects are done.  It’s infinitely better to be 100% done on a single project.

Innovation is all about learning.  And if the objective of innovation is learning, why not start with learning objectives?

Here’s a recipe for learning: define what you want to learn, figure how you want to learn, define what you’ll measure, work the learning plan, define what you learned and repeat.

With innovation, the learning is usually around what customers/users want, what new things (or processes) must be created to satisfy their needs and how to deliver the useful novelty to them.  Seems pretty straightforward, until you realize the three elements interact vigorously.  Customers’ wants change after you show them the new things you created. The constraints around how you can deliver the useful novelty (new product or service) limit the novelty you can create.  And if the customers don’t like the novelty you can create, well, don’t bother delivering it because they won’t buy it.

And that’s why it’s almost impossible to develop a formal innovation process with a firm sequence of operations.  Turns out, in reality the actual process looks more like a fur ball than a flow chart. With incomplete knowledge of the customer, you’ve got to define the target customer, knowing full-well you don’t have it right. And at the same time, and, again, with incomplete knowledge, you’ve got to assume you understand their problems and figure out how to solve them.  And at the same time, you’ve got to understand the limitations of the commercialization engine and decide which parts can be reused and which parts must be blown up and replaced with something new.  All three explore their domains like the proverbial drunken sailor, bumping into lampposts, tripping over curbs and stumbling over each other.  And with each iteration, they become less drunk.

If you create an innovation process that defines all the if-then statements, it’s too complicated to be useful.  And, because the if-thens are rearward-looking, they don’t apply the current project because every innovation project is different. (If it’s the same as last time, it’s not innovation.)  And if you step up the ladder of abstraction and write the process at a high level, the process steps are vague, poorly-defined and less than useful.  What’s a drunken sailor to do?

Define the learning objectives, define the learning plan, define what you’ll measure, execute the learning plan, define what you learned and repeat.

When the objective is learning, start with the learning objectives.

At first glance, it seems easy to run a good test, but nothing can be further from the truth.

The first step is to define the idea/concept you want to validate or invalidate.  The best way is to complete one of these two sentences: I want to learn that [type your idea here] is true. Or, I want to learn that [enter your idea here] is false.

Next, ask yourself this question: What information do I need to validate (or invalidate) [type your idea here]?  Write down the information you need.  In the engineering domain, this is straightforward: I need the temperature of this, the pressure of that, the force generated on part xyz or the time (in seconds) before the system catches fire.  But for people-related ideas, things aren’t so straightforward. Some things you may want to know are: how much will you pay for this new thing, how many will you buy, on a scale of 1 to 5 how much do you like it?

Now the tough part – how will you judge pass or fail?  What is the maximum acceptable temperature? What is the minimum pressure? What is the maximum force that can be tolerated? How many seconds must the system survive before catching fire?  And for people: What is the minimum price that can support a viable business? How many must they buy before the company can prosper? And if they like it at level 3, it’s a go. And here’s the most importance sentence of the entire post:

The decision criteria must be defined BEFORE running the test.

If you wait to define the go/no-go criteria until after you run the test and review the data, you’ll adjust the decision criteria so you make the decision you wanted to make before running the test. If you’re not going to define the decision criteria before running the test, don’t bother running the test and follow your gut.  Your decision will be a bad one, but at least you’ll save the time and money associated with the test.

And before running the test, define the test protocol.  Think recipe in a cookbook: a pinch of this, a quart of that, mix it together and bake at 350 degrees Fahrenheit for 40 minutes.  The best protocols are simple and clear and result in the same sequence of events regardless of who runs the test.  And make sure the measurement method is part of the protocol – use this thermocouple, use that pressure gauge, use the script to ask the questions about price and the number they’d buy.

And even with all this rigor, good judgement is still part of the equation.  But the judgment is limited to questions like: did we follow the protocol? Did the measurement system function properly? Do the initial assumptions still hold? Did anything change since we defined the learning objective and defined the test protocol?

To create formal learning objectives, to write well-defined test protocols and to formalize the decision criteria before running the test require rigor, discipline, time and money.  But, because the cost of making a bad decision is so high, the cost of running good tests is a bargain at twice the price.

The trouble with innovation is it’s risky.  Sure, the upside is nice (increased sales), but the downside (it doesn’t work) is distasteful. Everyone is looking for the magic pill to change the risk-reward ratio of innovation, but there is no pill.  Though there are some things you can do to tip the scale in your favor.

All problems are business problems.  Problem solving is the key to innovation, and all problems are business problems.  And as companies embrace the triple bottom line philosophy, where they strive to make progress in three areas – environmental, social and financial, there’s a clear framework to define business problems.

Start with a business objective.  It’s best to define a business problem in terms of a shortcoming in business results. And the holy grail of business objectives is the growth objective.  No one wants to be the obstacle, but, more importantly, everyone is happy to align their career with closing the gap in the growth objective.  In that way, if solving a problem is directly linked to achieving the growth objective, it will get solved.

Sell more.  The best way to achieve the growth objective is to sell more. Bottom line savings won’t get you there.  You need the sizzle of the top line. When solving a problem is linked to selling more, it will get solved.

Customers are the only people that buy things.  If you want to sell more, you’ve got to sell it to customers. And customers buy novel usefulness.  When solving a problem creates novel usefulness that customers like, the problem will get solved.  However, before trying to solve the problem, verify customers will buy what you’re selling.

No-To-Yes.  Small increases in efficiency and productivity don’t cause customers to radically change their buying habits.  For that your new product or service must do something new. In a No-To-Yes way, the old one couldn’t but the new one can. If solving the problem turns no to yes, it will get solved.

Would they buy it? Before solving, make sure customers will buy the useful novelty. (To know, clearly define the novelty in a hand sketch and ask them what they think.) If they say yes, see the next question.

Would it meet our growth objectives? Before solving, do the math. Does the solution result in incremental sales larger than the growth objective? If yes, see the next question.

Would we commercialize it? Before solving, map out the commercialization work. If there are no resources to commercialize, stop.  If the resources to commercialize would be freed up, solve it.

Defining is solving. Up until now, solving has been premature. And it’s still not time. Create a functional model of the existing product or service using blocks (nouns) and arrows (verbs). Then, to create the problem(s), add/modify/delete functions to enable the novel usefulness customers will buy.  There will be at least one problem – the system cannot perform the new function. Now it’s time to take a deep dive into the physics and bring the new function to life.  There will likely be other problems.  Existing functions may be blocked by the changes needed for the new function. Harmful actions may develop or some functions will be satisfied in an insufficient way.  The key is to understand the physics in the most complete way.  And solve one problem at a time.

Adaptation before creation. Most problems have been solved in another industry. Instead of reinventing the wheel, use TRIZ to find the solutions in other industries and adapt them to your product or service.  This is a powerful lever to reduce innovation risk.

There’s nothing worse than solving the wrong problem.  And you know it’s the wrong problem if the solution doesn’t: solve a business problem, achieve the growth objective, create more sales, provide No-To-Yes functionality customers will buy, and you won’t allocate the resources to commercialize.

And if the problem successfully runs the gauntlet and is worth solving, spend time to define it rigorously.  To understand the bedrock physics, create a functional of the system, add the new functionality and see what breaks.  Then use TRIZ to create a generic solution, search for the solution across other industries and adapt it.

The key to innovation is problem solving. But to reduce the risk, before solving, spend time and energy to make sure it’s the right problem to solve.

It’s far faster to solve the right problem slowly than to solve the wrong one quickly.

There are many definitions for creativity and innovation, but none add meaningfully to how the work is done. Though it’s clear why the work is important – creativity and innovation underpin corporate prosperity and longevity – it’s especially helpful to know how to do it.

At the most basic level, creativity and innovation are about problem solving.  But it’s a special flavor of problem solving.  Creativity and innovation are about problems solving new problems in new ways.  The glamorous part is ‘solving in new ways’ and the important part is solving new problems.

With continuous improvement the same problems are solved over and over. Change this to eliminate waste, tweak that to reduce variation, adjust the same old thing to make it work a little better.  Sure, the problems change a bit, but they’re close cousins to the problems to the same old problems from last decade. With discontinuous improvement (which requires high levels of creativity and innovation) new problems are solved.  But how to tell if the problem is new?

Solving new problems starts with seeing problems differently.

Systems are large and complicated, and problems know how to hide in the nooks and crannies. In a Where’s Waldo way, the nugget of the problem buries itself in complication and misuses all the moving parts as distraction. Problems use complication as a cloaking mechanism so they are not seen as problems, but as symptoms.

Telescope to microscope. To see problems differently, zoom in.  Create a hand sketch of the problem at the microscopic level.  Start at the system level if you want, but zoom in until all you see is the problem.  Three rules: 1. Zoom in until there are only two elements on the page. 2. The two elements must touch. 3. The problem must reside between the two elements.

Noun-verb-noun. Think hammer hits nail and hammer hits thumb.  Hitting the nail is the reason people buy hammers and hitting the thumb is the problem.

A problem between two things. The hand sketch of the problem would show the face of the hammer head in contact with the surface of the thumb, and that’s all.  The problem is at the interface between the face of the hammer head and the surface of the thumb. It’s now clear where the problem must be solved. Not where the hand holds the shaft of the hammer, not at the claw, but where the face of the hammer smashes the thumb.

Before-during-after. The problem can be solved before the hammer smashes the thumb, while the hammer smashes the thumb, or after the thumb is smashed.  Which is the best way to solve it? It depends, that’s why it must be solved at the three times.

Advil and ice. Solving the problem after the fact is like repair or cleanup. The thumb has been smashed and repercussions are handled in the most expedient way.

Put something between. Solving the problem while it happens requires a blocking or protecting action. The hammer still hits the thumb, but the protective element takes the beating so the thumb doesn’t.

Hand in pocket. Solving the problem before it happens requires separation in time and space. Before the hammer can smash the thumb it is moved to a safe place – far away from where the hammer hits the nail.

Nail gun. If there’s no way for the thumb to get near the hammer mechanism, there is no problem.

Cordless drill. If there are no nails, there are no hammers and no problem.

Concrete walls. If there’s no need for wood, there’s no need for nails or a hammer. No hammer, no nails, no problem.

Discerning between symptoms and problems can help solve new problems. Seeing problems at the micro level can result in new solutions. Looking closely at problems to separate them time and space can help see problems differently.

Eliminating the tool responsible for the problem can get rid of the problem of a smashed thumb, but it creates another – how to provide the useful action of the driven nail.  But if you’ve been trying to protect thumbs for the last decade, you now have a chance to design a new way to fasten one piece of wood to another, create new walls that don’t use wood, or design structures that self-assemble.

When it’s time to innovate, the first task is usually to define the Idealized Future State (IFS).  The IFS is a word picture that captures what it looks like when the innovation work has succeeded beyond our wildest dreams. The IFS, so it goes, is directional so we can march toward the right mountain and inspirational so we can sustain our pace over the roughest territory.

For the IFS to be directional, it must be aimed at something – a destination.  But there’s a problem. In a sea of uncertainty, where the work has never been done before and where there are no existing products, services or customers, there are an infinite number of IFRs/destinations to guide our innovation work.  Open question – When the territory is unknown, how do we choose the right IFS?

For the IFS to be inspirational, it must create yearning for something better (the destination). And for the yearning to be real, we must believe the destination is right for us. Open question – How can we yearn for an IFS when we really can’t know it’s the right destination?

Maps aren’t the territory, but they are a collection of all possible destinations within the design space of the map.  If you have the right map, it contains your destination. And for a long time now, the old paper maps have helped people find their destinations. But on their own maps don’t tell us the direction to drive.  If you have a map of the US and you want to drive to Kansas, in which direction do you drive? It depends. If in California, drive east; if in Mississippi, drive north; if in New Hampshire, drive west; and in Minnesota, drive south. If Kansas is your idealized future state, the map alone won’t get your there.  The direction you drive depends on your location.

GPS has been a nice addition to maps. Enter the destination on the map, ask the satellites to position us globally and it’s clear which way to drive. (I drive west to reach Kansas.) But the magic of GPS isn’t in the electronic map, GPS is magic because it solves the location problem.

Before defining the idealized future state, define your location. It grounds the innovation work in the reality of what is, and people can rally around what is. And before setting the innovation direction with the IFS, define the next problems to solve and walk in their direction.

It’s not enough to sell things to customers, because selling things is transactional and, over time, transactional selling deteriorates into selling on price. And selling on price is a race to the bottom.

Sales must move from transactional to relational, where people in the sales organization become trusted advisers and then something altogether deeper. At this deeper level of development, the sales people know the business as well as the customer, know where the customer wants to go and provide unique perspective and thoughtful insight.  That’s quite a thing for sales, but it’s not enough.  Sales must become the conduit that brings the entire company closer to the customer and their their work.

When the customer is trying to figure out what’s next, sales brings in a team of marketing, R&D and manufacturing to triangulate on the future.  The objective is to develop deep understanding of the customer’s world.  The understanding must go deeper than the what’s.  The learning must scrape bottom and get right down to the bedrock why’s.

To get to bedrock, marketing leads learning sessions with the customer.  And it all starts by understanding the work.  What does the customer do? Why is it done that way? What are the most important processes? How did they evolve? Why do they flow the way they do? These aren’t high-level questions, they are low-level, specific questions, done in front of the actual work.

The mantra – Go to the work.

When the learning sessions are done well, marketing includes experts in manufacturing and R&D.  Manufacturing brings their expertise in understanding process and R&D brings their expertise in products and technologies.  And to understand the work the deepest way, the tool of choice is the Value Stream Map (VSM).

Cross-organization teams are formed (customer, sales, marketing, manufacturing, and R&D) and are sent out to create Value Steam Maps of the most important processes.  (Each team is supported by a VSM expert.)  Once the maps are made, all the teams come back together to review the them and identify the fundamental constraints and how to overcome them.  The solutions are not limited to new product offerings, rather the solutions could be training, process changes, policy changes, organizational changes or business model changes.

Not all the problems are solved in the moment.  After the low hanging fruit is picked, the real work begins.  After returning home, marketing and R&D work together to formulate emergent needs and create new ways to meet them.  The tool of choice is the IBE (Innovation Burst Event).

To prepare for the IBE, marketing and R&D formalize emergent needs and create Design Challenges to focus the IBE teams.  Solving the Design Challenges breaks the conflicts creates novel solutions that meet the unmet needs.  In this way, the IBE is a pull process – customer needs create the pull for a solution.

The IBE is a one or two-day event where teams solve the Design Challenges by building conceptual prototypes (thinking prototypes).  Then, they vote on the most interesting concepts and create a build plan (who, what, when).  The objective of the build plan is to create a Diabolically Simple Prototype (DSP), a functional prototype that demonstrates the new functionality. What makes it diabolical is quick build time.  At the end of the IBE is a report out of the build plan to the leader who can allocate the resources to execute it.

In a closed-loop way, once the DSP is built, sales arranges another visit to the customer to demonstrate the new solution.  And because the prototype designed to fulfill the validated customer need, by definition, the prototype will be valuable to the customer.

This full circle process has several novel elements, but the magic is in the framework that brings everyone together.  With the process, two companies can work together effectively to achieve shared business objectives.  And, because the process brings together multiple functions and their unique perspectives, the solutions are well-thought-out and grounded in the diversity of the collective.

Ideas are all talk and no action.  Ideas are untested concepts that have yet to rise to the level of practicality.  You can’t sell an idea and you can’t barter with them. Ideas aren’t worth much.

A prototype is a physical manifestation of an idea. Where ideas are ethereal, prototypes are practical. Where ideas are fuzzy and subject to interpretation, prototypes are a sledge hammer right between the eyes.  There is no arguing with a prototype. It does what it does and that’s the end of that. You don’t have to like what a prototype stands for, but you can’t dismiss it. Where ideas aren’t worth a damn, prototypes are wholly worth every ounce of effort to create them.

If Camp A says it will work and Camp B says it won’t, a prototype will settle the disagreement pretty quickly.  It will work or it won’t.  And if it works, the idea behind it is valid.  And if it doesn’t, the idea may be valid, but a workable solution is yet-to-be discovered.  Either way, a prototype brings clarity.

Prototypes are not elegant.  Prototypes are ugly. The best ones do one thing – demonstrate the novel idea that underpins them. The good ones are simple, and the best ones are diabolically simple. It is difficult to make diabolically simple prototypes (DSPs), but it’s a skill that can be learned.  And it’s worth learning because DSPs come to life in record time. The approach with DSPs is to take the time up front to distill the concept down to its essence and then its all-hands-on-deck until it’s up and running in the lab.

But the real power of the DSP is that it drives rapid learning.  When a new idea comes, it’s only a partially formed.  The process of trying to make a DSP demands the holes are filled and blurry parts are brought into focus.  The DSP process demands a half-baked idea matures into fully-baked physical embodiment.  And it’s full-body learning.  Your hands learn, your eyes learn and your torso learns.

If you find yourself in a disagreement of ideas, stop talking and start making a prototype. If the DSP works, the disagreement is over.

Diabolically simple prototypes end arguments. But, more importantly, they radically increase the pace of learning.

By definition, when the work is new there is uncertainty.  And uncertainty can be stressful. But, instead of getting yourself all bound up, accept it.  More than that, relish in it.  Wear it as a badge of honor.  Not everyone gets the chance to work on something new – only the best do.  And, because you’ve been asked to do work with a strong tenor of uncertainty, someone thinks you’re the best.

But uncertainty is an unknown quantity, and our systems have been designed to reject it, not swim in it.  When companies want to get serious they drive toward a culture of accountability and the new work gets the back seat.  Accountability is mis-mapped to predictability, successful results and on time delivery.  Accountability, as we’ve mapped it, is the mortal enemy of new work.  When you’re working on a project with a strong element of uncertainty, the only certainty is the task you have in front of you.  There’s no certainty on how the task will turn out, rather, there’s only the simple certainty of the task.

With work with low uncertainty there are three year plans, launch timelines and predictable sales figures. Task one is well-defined and there’s a linear flow of standard work right behind it – task two through twenty-two are dialed in. But when working with uncertainty, the task at hand is all there is.  You don’t know the next task.  When someone asks what’s next the only thing you can say is “it depends.”  And that’s difficult in a culture of traditional accountability.

An “it depends” Gannt chart is an oxymoron, but with uncertainty step two is defined by step one.  If A, then B.  But if the wheels fall off, I’m not sure what we’ll do next.  The only thing worse than an “it depends” Gantt chart is an “I’m not sure” Gannt chart.  But with uncertainty, you can be sure you won’t be sure.  With uncertainty, traditional project planning goes out the window, and “it depends” project planning is the only way.

With uncertainty, traditional project planning is replaced by a clear distillation of the problem that must be solved.  Instead of a set of well-defined tasks, ask for a block diagram that defines the problem that must be solved.  And when there’s clarity and agreement on the problem that must be solved, the supporting tasks can be well-defined.  Step one – make a prototype like this and test it like that. Step two – it depends on how step one turns out.  If it goes like this then we’ll do that.  If it does that, we’ll do the other.  And if it does neither, we’re not sure what we’ll do.  You don’t have to like it, but that’s the way it is.

With uncertainty, the project plan isn’t the most important thing.  What’s most important is relentless effort to define the system as it is.  Here’s what the system is doing, here’s how we’d like it to behave and, based on our mechanism-based theory, here’s the prototype we’re going to build and here’s how we’re going to test it.  What are we going to do next?  It depends.

What’s next? It depends. What resources do you need? It depends. When will you be done? It depends.

Innovation is, by definition, work that is new.  And, innovation, by definition, is uncertain.  And that’s why with innovation, it depends.  And that’s why innovation is difficult.

And that’s why you’ve got to choose wisely when you choose the people that do your innovation work.
