Development problems and lean development

Development problems and making designs lean

Timothy Schipper

Early in my career, I was a product developer.   However, I quickly became disenchanted with the whole development process.  I loved the engineering part of the job, solving problems and finding solutions.  It was the lack of alignment, loop backs, and rework that discouraged me.   I found that the whole process lacked focus and that projects spawned huge amounts of rework.  Rework appeared in many forms – late design changes, added requirements, and a general lack of focus.  I found that development only address part of the value equation, and usually did not address the problem of anticipating manufacturing wastes and design inefficiencies.

My career took a few turns.   I left product development after a few years, working as an IT project manager and then as a manager.  It was during this period of time that I found lean methods.   I studied how lean was applied to manufacturing and also the office.   I found that the lean tools provided a framework for looking at problems, and working on root cause elimination.   The idea  of continuous improvement appealed to me as a way to move an organization to be more efficient.  Lean became my new passion.   Nearly 10 years and 120 workshops later, I had mastered the art of applying lean to the carpeted areas of the business.  It was during that journey that I discovered another application of lean.

Have you ever wondered if lean could be applied to the design world?  Could it be used as a method to design more efficiently?   Could it inform a product that was still on the drawing board, or should I say still in the CAD system?   It is clear that it could be applied after the fact, once products were designed and hit the factory floor.  Lean applied in manufacturing creates efficient value streams that run at a constant TAKT time with minimal inventory.  But what does lean look like when applied to design?

The discovery I made was that lean could be applied to design just as well as it has been applied to manufacturing.  Much of the language is the same, but the tactics are quite different.    About 5 years ago, I was introduced to the topic of designs that are lean at a Huthwaite Institute Summit.   It allowed me to synthesize my thinking and explore the world of design in a new way.  This proved to be a thinking model as well as a guide for individuals and teams on how to apply lean to their development process.   Thinking and reading Bart Huthwaite’s books inspired me to create LEAN products.both products and processes that are lean from the start.

The methods works well with teams who need to innovate quickly and speed development along.  It is unique in that it works on both the process of development and on the product that is being designed.   One of my favorite quotes is that for something to be lean it has to be lean from the start.  In other words, wastes have to be designed out for the system upfront.

I was inspired to write about how development could generate innovative products and lean process.  The book Innovative LEAN Development was one of the ways that I explored the idea of lean applied to development.  I co-authored the book with my colleague, Mark Swets.  It is our attempt to make a contribution to the knowledge base of lean development and design.

If you have been frustrated with the development experience as we were, then I encourage to investigate the lean development method.   We have witnessed many teams who successfully applied lean development to improve their process and the quality of their products.

If you find the idea of lean for development intriguing and would like to learn more, please respond and tell me your challenges and frustrations with the development process.  Let’s explore together how lean can remove your most difficult development gaps.  I only wish that I had found the lean method earlier in my career.

Discovery – and Rapid Learning Cycles

What do you want to discover today?

Heuristic (pronounced /hjʉˈrɪstɨk/, from the Greek “Εὑρίσκω” for “find” or “discover”) is an adjective for experience-based techniques that help in problem solving, learning and discovery. Archimedes is said to have shouted “Heureka” (later converted to “Eureka”) after discovering the principle of displacement in his bath.  You might remember from physics that displacement is the principle that a floating object will displace its own weight in water.

Heuristics is the art of solving a problem in the best or most optimal way that is possible.  The optimal solution will be the most elegant one that is possible.  In nature, we find that the solutions have been created to be the most optimal, with nothing wasted.  The design of a plant is unique to its environment, taking in the right amount of light from the sun and nourishment from the soil.

When humans attempt to solve a knotty, or difficult, problem, we have to use a trial-and-error method.  We are limited, and do not take all the variables and parameters into account.

Enter Learning Cycles … Rapid Learning Cycles (RLCs) are a method of laying out the problem and approaching it with a series of rapid iterations of building, prototyping, and testing each one.

The best developers and inventors practice the art of RLCs. Thomas Edison reportedly tried something on the order of 3,000 materials for the filament of the electric lightbulb.

Or take the case of Charles Goodyear.  By the mid 1830s, it seemed as though the rubber industry in America was going under. The problem with the new material was that it was unstable – becoming completely solid and cracking in the winter, then melting into goo in the summer. Miraculously the industry was saved by inventor Charles Goodyear – a man with no knowledge of chemistry who worked stubbornly and tenaciously to develop vulcanized rubber.

After incidentally learning about rubber’s fatal flaw, Charles Goodyear became determined to invent a way to make the substance more stable. Without a steady job, he lived for years off of advancements from investors. When his experiments with rubber continually failed, Goodyear reduced his family to poverty, was jailed for debt and derided by society as a mad man.

Undeterred, inventor Charles Goodyear finally found that, by uniformly heating sulfur- and lead-fortified rubber at a relatively low temperature, he could render the rubber melt-proof and reliable. He patented the process in 1844, licensed it to manufacturers and was ultimately hailed as a genius.

Years after his death, when the age of automobiles dawned, two brothers from Ohio decided to name their company after the man who made their product possible – hence Goodyear tires were born.

So, discover something today using rapid learning cycles… and don’t be discouraged by the iterative nature of problem solving.
