Muri – Overburden


Muri is waste associated with pushing people, processes and equipment beyond the limits or overburdening. An organization may be enamored of working large numbers of overtime hours, but any benefit for such some at a cost, and this is an example of overburdening.

I once worked at a place in which the employees averaged being at the organization for between 10 – 20 years, and had vacation time commensurate with being within the organization per the company benefits manual. The people that had been with the company that long had more than 4 weeks of vacation, which is 160 hours off of the 2000 hours or total work hours approximates 1840.  On top of this time off, the company also offered special days that it gave off to everybody – think Thanksgiving and Christmas for example.  Yet when it came to calculate the work the organization could undertake, the organization used 1980 per person to estimate the total amount of … Continue reading


Muda – Waste


For those familiar with the lean approach to the work or the Toyota Way, you my already know about the concept of Muda. Muda is one of the three categories associated with lean that impact performance and costs to the organization.  Muda is regarded to have seven waste types or areas or actions that cause waste.

Over Production

Just like it sounds, making more of something than the need for that something.  This does not just mean parts, but also extends to work product deliveries throughout the work pipeline. Think SIPOC (Supplier-Input-Process-Output-Customer), in this case any output from a process (P) delivered before the depending process (C) or work can start, leaving the work product just sitting there.  Another variant of this waste would be working on products that are not for the next work process, but some prioritized work that is further down or upstream.  When this is not coordinated well, we end up with rework, and if changes are required … Continue reading


Starting a Fire


Do you know how to start a fire?  I am not talking about charcoal briquettes, or the use of combustion material such as  lighter fluid, gasoline, or those special wax products that can be used in your fireplace, no propane or gas used either.

I’m talking about the fires we make in the woods when we go camping. It is okay if you do not know how, in fact my life as had quite a few times when my boy scout experiences have been a benefit to more than my family or those with whom I am camping.  My son and I have made many campfires for cooking out or roasting marsh mellows. Before this, I had camped out without a tent and used the fire for warmth (and to keep away the vermin while we slept).  We have started fires when the material may be damp, but that is not to suggest that it is easy to start a fire … Continue reading


Tools and Teams


I recently saw a post on Twitter from the Great John Cutler on allow the team to pick the tools that they use to do the work.  Generally, this is not a bad idea, but not necessarily a great idea either.  It sort of depends.

 

 

My experience in companies that also have hardware parts associated with the software, each group selecting their tools comes at a great disadvantage when it comes to understanding the various work products as it moves through the organization.  It is not possible for one team to see what the other team has done, when the tools are not connected, or each group selects what that individual group needs without consideration of the departments that are depending or associated with the work.  In these cases, a product life cycle management tool that connects the various work departments and work packages can help tie all of these together. Consider a vehicle manufacturer that … Continue reading


Kanban and Visual Management


Kanban and Visual Management

Kanban is a lean method for identifying and managing the work and the flow, and it does so by creating a pull through environment.  We will start by identifying the work we need to do. Each work item we need to do will end up on an individual card.  The cards will be “pulled” as we have the time and talent to commence that specific work element. The card then moves from the backlog of work items, to the WiP or Work in Progress section of the visual management board.  The visual board may have headings such as:

Backlog Work in Progress (WiP) Work for Review Work Completed / Demonstrated

We will pull items from the backlog and place the card in the state that corresponds to the work, for example, the work moves from backlog to work in progress as the work commences.  It is easy for anybody to see the status of the work. … Continue reading


Evolution of the Horseless Carriage


In preparation for our trip to Eindhoven University of Technology to lecture on Configuration Management, we provide a brief excerpt on the evolution of the horseless cariage.

Traditionally new market segments open due to the need to solve a problem. Such problems may be real as in the case of the environmental crisis solved by the automobile or the need may be concocted. New markets and products are rarely developed through the inspiration of a single individual. The automotive market came about through a synergy of the existing body of knowledge and other environmental conditions both in the marketplace and in the nature.

One topic of discussion at the world’s first international urban planning conference in 1898 was the growing health concerns due to horse excretions and the creatures that accompanied them. As the primary means of locomotion for wagons and other forms of transport, horse populations exceeded human population in cities.*

Manufacturers of “horseless carriages” using steam, … Continue reading


My Career Part 2


Career; of Motorcycles and Trucks

This blog continues from my last post describing the first part of my career.  We continue with the tire pressure monitoring system.  In those days, and for many years before that, my preferred form of transport was motorcycle.  I had an accident a few years before taking this job that broke some bones in my wrist (not my first nor last set of broken bones), in fact I got the bike fixed and was riding it through the winter with my right hand in a cast, and with multiple socks on to keep my hand warm.  I should mention that my preferred transportation was motorcycle, at least in part, because it was my only source of transportation.  Eventually, my fourth job before my professional career started, the manager of the U-Haul at which I worked during my undergraduate education came across a wonderful, and old, Toyota station wagon complete with the fake wood … Continue reading
