Curious Cat Management Improvement Blog Ranking

I created a ranking of top management improvement blogs for fun. There is no way to objectively rate blogs by how worthy or valuable they are. I just wanted to create a listing that ranked blogs I thought were worth reading using a collection of metrics that I think have some merit (even if that merit is fairly limited).

Here are the top 10 as of now (it will change over time):

The most important factor is my selection of what blogs to include in the first place. Then I rank them using several other factors: link popularity (how many links to the sites, with more authoritative links carrying more weight), a subjective ranking by me, traffic (using an admittedly pretty flawed measure of traffic – but again this is just for fun so…), Twitter authority of the author, domain authority (based on links, not just to the blog, but the web site overall).

I have also created a ranking for personal travel blogs, leadership blogs and will add a few more.

I hope you enjoy the ranking and really hope you find a few new blogs you benefit from reading. There are quite a few interesting management improvement blogs, though honestly there are many fewer good posts than there were 5 years ago. Most of the best active blogs from 6 or 7 years ago are either much much less active today or are gone altogether. But even so there are still quite a few valuable blogs for managers to read.

Magnetic White-Board Kanban Card Options

Just some quick ideas for Kanban whiteboard magnetic card options from a question I answered on Reddit.

Here is the best lean solution: Trying Out My Agile Kanban Board from Jon Miller.

Why, well mainly I am kidding about it being the best, but if you don’t read his Gemba Panta Rei blog you should! Go add it to your RSS feed reader, before you continue with this post.

Ok, welcome back. In addition to thinking his blog is great the solution from his blog is very flexible and easy – though it isn’t quite a packaged solution (as asked for on Reddit). Also that post provides some good insight into the thinking behind the board (as well as how to create your own).

Another silly site, that sells some sort of solution, blocked my access because they don’t sell in the country my computer reported being located in. So I didn’t give them a free plug (assuming their product was decent which it might be?). Very dumb design if you ask me; well even though you didn’t ask, I told you anyway.

Localization that impedes users rather than helping them seems far far too common in my experience. Mapping (and related – find closest…) uses are about the only localization stuff I find useful – country based localization I nearly always find annoying or crippling. And showing my location on a map is totally awesome (especially as I travel around as a tourist – or really in whatever capacity). Such bad design and poor usability decisions cost companies money.

Toyota Understands Robots are Best Used to Enhance the Value Employees Provide

Toyota has always seen robotics as a way to enhance what staff can do. Many USA executives think of robotics as a way to reduce personnel. Toyota wants to use the brainpower of employees to continually improve the organization. Toyota wants to free people for monotonous or dangerous work to let them use their minds.

Humans Steal Jobs From Robots at Toyota

Humans are taking the place of machines in plants across Japan so workers can develop new skills and figure out ways to improve production lines and the car-building process.

“We cannot simply depend on the machines that only repeat the same task over and over again,” Kawai said. “To be the master of the machine, you have to have the knowledge and the skills to teach the machine.”

Kawai, 65, started with Toyota during the era of Taiichi Ohno, the father of the Toyota Production System envied by the auto industry for decades with its combination of efficiency and quality. That means Kawai has been living most of his life adhering to principles of kaizen, or continuous improvement, and monozukuri, which translates to the art of making things.

“Fully automated machines don’t evolve on their own,” said Takahiro Fujimoto, a professor at the University of Tokyo’s Manufacturing Management Research Center. “Mechanization itself doesn’t harm, but sticking to a specific mechanization may lead to omission of kaizen and improvement.”

We need more companies to learn from the executives at Toyota. They show real respect for people. They are not focused on how much they can extract from the corporate treasury to build themselves castles at the expense of other employees, customers and stockholders as far too many USA executives are.

Toyota has been extremely innovative in investing in robotics as human assistants (partially this is due to the extreme demographic problems Japan faces): Toyota Develops Thought-controlled WheelchairToyota’s Partner RobotToyota Winglet – Personal Transportation Assistance.

You are a Fool if You Do What I Say

Guest post from Mark Graban

There’s an interesting quote from Taiichi Ohno in “Taiichi Ohno’s Workplace Management,” which I was re-reading today…

“You are a fool if you do what I say. You are a greater fool if you don’t do as I say. You should think for yourself and come up with better ideas than mine.”

The best examples of Lean in healthcare are examples where leaders and organizations learned, but did not blindly copy. Sami Bahri DDS (the “lean dentist”) read Deming, Shingo, Ohno, etc. and had to figure this out himself, rather than copying some other dentist.

ThedaCare is the first to say “don’t directly copy what we do.”

We can learn from others, run our own experiments to see what works, and keep improving to make it better than even Ohno or Shingo would have imagined.

Leadership and Management

I don’t think the attempts to separate leadership and management are useful. I read plenty of things that are variations on Peter Drucker’s:

“Management is doing things right; leadership is doing the right things.”

A manager that is not concerned about doing the right things is a lousy manager. And a leader that doesn’t care about doing things right is a lousy leader.

Another theme of this contrasting type quote says some version of:

“Managers care about efficiency and leaders care about effectiveness”

A manager who doesn’t strive to be effective is also a lousy manager. It is also odd to suppose the detached leader (the type that lets the manager deal with the mundane while they dream), one that doesn’t concern themselves with customer focus, value chains, going to the gemba really has a clue about effectiveness. The idea seems mainly to view a manager is a cog looking at some tiny process and making it efficient without understanding the organization as a system or value chains or customer focus.

I think, the main problem is all of the attempts to contrast leaders and managers. Much of the time people are saying managers don’t do things they certainly should be doing.

The desire to express how leadership traits can be used by those without organizational authority are useful. Discussion of how certain traits can be seen as within the domain of leadership I suppose may be useful (it can help our minds see how various traits and practices combine to help get results – and we can categorize these under “leadership”).

Leaders that are primarily “big thinkers” and motivators without a clue about how to actually do the things they advocate (the model of “managers” deal with the implementation with blinders to the system while “leaders” are “above the fray”) is not useful in my opinion. It does note a somewhat common practice (in organizations today) but not one that is wise. Separating leadership from the gemba is not wise. Separating leadership from a deep understanding of customers is not wise. Separating leadership from how the organization actually works is not wise.

Plenty of others seem to disagree with my opinion though, there are many articles, blog posts, podcasts, talks… on separating leadership from management.

Business 901 Podcast with Me: Deming’s Management Ideas Today

I recently was interviewed for a podcast by Joe Dager, at Business 901: Dr. Deming on Lean in 2012. I hope you enjoy the podcast.

Listen to this podcast.

Here are some links related to items I mention in the podcast:

Some blog posts that expand on some points I made in the podcast:

Respect for Everyone

TL;DR – The two pillars of the Toyota Way are: respect for people and continuous improvement.

One of the big reasons my career followed the path it did (into management improvement) was due to the impact of respect for people. My father was a professor (in statistics, engineering and business) and consulted with organizations to help them achieve better results. To achieve results he took advantage of the gains possible when using statistical tools to manage with respect for people.

Managing Our Way to Economic Success: Two Untapped Resources, 1986: “American organizations could compete much better at home and abroad if they would learn to tap the potential information inherent in all processes and the creativity inherent in all employees.”

After he died, for years, people would talk to me about the difference he made in their lives (at conferences mainly). Other than those with PhD’s in statistics (of which there were many, but a very small number compared to all the others) the thing that made a difference was respect for people. Those who chose to talk to me are obviously a self selected group. But of those, the people that made the largest impact on me basically said he talked to me as though everything I said mattered. He didn’t talk down to me. He helped me see how I could help improve: the organization and my own skills and abilities.

This didn’t happen 5 times or 10 times of 20 times, it happened many more times than that. Year after year of this helped push me to stick with management improvement. These served as a great incentive to perserve as I ran into the typical difficulties actually improving management systems.

The senior executives he talked to were not very impressed that he spoke to them with respect. So none mentioned that with awe, but a few did notice that he was able to connect with everyone – the senior executives, nurses, people on the factory floor, secretaries, salespeople, front line staff, engineers, janitors, middle managers, doctors, union leaders. The senior executives were more likely to be impressed by the success and his technical ability and knowledge as well as communication skill. Doctors, statisticians and engineers were more impressed with knowledge, technical skill, skill as a teacher and advice.

5s at NASA

NASA did some amazing things culminating with landing on Moon. Much of what they did was doing many small things very well. They used 5s, checklists, gemba thinking, usability, simplicity, testing out on a small scale and much more.

Here are a few photos from the Smithsonian Air and Space museum in Washington DC. I also have some nicer NASA 5s photos from the new Annex near Dulles Airport, but, ironically, I can’t find them.

These kits were used by NASA astronauts on the Apollo 11 mission to the moon. Obviously NASA had to have everything that might be needed where it was needed (picking up something from the supply closet in building 2 wasn’t an option).

New Deadly Diseases

Management and the economy keep evolving. Many good things happen. In the last decade the best things are probably the increased deep adoption of lean thinking in many organization. and the adoption of lean and Deming methods in software development (agile software development, kanban and lean startup [which I do realize isn’t limited to software development]).

Sadly all the deadly diseases Dr. Deming described remain. And, as I said in 2007, I think 2 new diseases have become so widespread and so harmful they have earned their place alongside the 7 deadly diseases (which started as the 5 deadly diseases). The new deadly diseases are:

  • extremely excessive executive pay
  • systemic impediments to innovation

In my view these 2 diseases are more deadly to the overall economy than all but the broken USA health system. The systemic impediments to innovation are directly critical to small percentage (5%?) of organizations. But the huge costs of the blocks to innovation and the huge “taxes” (extorted by those using the current system to do the oposite of what it should be doing) are paid by everyone. The costs come from several areas: huge “taxes” on products (easily much greater than all the taxes that go to fund our governments), the huge waste companies have to go through due to the current system (legal fees, documentation, delayed introduction, cross border issues…) and the denial of the ability to use products and services that would improve our quality of life.

The problems with extremely excessive executive pay are well known. Today, few sensible people see the current executive pay packages as anything but the result of an extremely corrupt process. Though if their personal pocketbook is helped by justifying the current practices, some people find a way to make a case for it. But excluding those with an incentive to be blind, it is accepted as a critical problem.

More people understand the huge problems with our patent and copyright systems everyday, but the understanding is still quite limited. Originally copyright and patents were created to provide a government granted monopoly to a creator in order to reward that creator for contributing to the development of society. Copyrights and patents are government granted interventions in the free market. They are useful. They are wise policy.

Value Stream Mapping for Fun and Profit

Guest post by Evan Durant, author of the Kaizen Notebook blog.

I tend to get a little preachy about the importance of value stream maps, but they really can be useful tools not only to plan an improvement effort but also to monitor your progress going forward. In particular they provide a way to quantify the impact of changes to your process. Here’s a real life example as a case in point.

For a particular value stream a team went to gemba, followed the flow of material and information, collected process cycle times, and counted inventory. When everything was mapped and all the data tallied, here was the current state that they came up with:

Total Lead Time:
16.8 days
Process Lead Time: 2.2 days
Process Time: 1.9 days
Operator Cycle Time: 8.2 minutes

So what does all this mean? First of all the Total Lead Time represents the amount of time that a new piece of raw material would take to enter the value stream, be worked on, wait around with all the rest of the material in process, and then finally make its way to the customer. This number is usually driven higher by large amounts of in-process inventory caused by pushing between operations.

Second, the Process Lead Time is the amount of time it would take to process a single batch through the process, if it didn’t have to wait behind any other batches. Note that even though parts are processed one at a time through all of the manual operations, a certain amount of batching is required to overcome long machine cycle times in automatic operations. Also we do not ship parts to the customer one at a time, but rather in standard package sizes.

Third, we have the Process Time. This is the total amount of value added time, manual and automatic processing, that a part sees in the value stream.

Finally the Operator Cycle Time (also called manual time) is the amount of actual “touch” time required to make a part. The difference between the Process Time and the Operator Cycle Time is the Machine Cycle Time (also called automatic time). This is when a batch of parts is on a machine that does not require any operator intervention during a cycle. (We have a lot of machine cycle time in this value stream.)

Then the team applied the concepts of flow and pull to reduce overproduction and pace the value stream to the rate of customer demand. The results of the future state map were as follows:
