Takt Time - Does this apply to my process?


One of the comments I get from management, team members, and even fellow lean consultants is that takt time doesn't apply in many settings including healthcare and admin processes like recruiting.  If we go back to the most basic applications of lean, we are trying to see and eliminate waste (continuously improve), and simultaneously show respect for people. In seeing and eliminating waste in the manufacturing sector, we always begin with the takt time calculation. 

Refreshing everyone's mind, takt time is defined as the available time to do the work divided by the volume of work to be done. This theoretical calculation leads to understanding the rhythm of output. The entire lean system runs to this rhythm. Space requirements, kanban inventory levels, staffing levels, shift schedules, and equipment utilization all are determined from the takt time calculation.

To presume that space requirements, scheduling assignments, inventory levels, and equipment utlization are not concerns within administrative processes and healthcare would be incorrect.

The challenge with the takt time calculation in some applications is due to the variability in demand. To overcome this variability, we often have to look at takt time based on the day of the week and often by the hour of the day.  Or in some cases over a longer horizon like by week or my month.  We may even have to look at takt time differently by season (trauma season and flue season come to mind)

Once we are looking at the appropriate time intervals, the takt time calculation and all the corresponding tools of time observation, cycle time -takt time loading diagrams, standard work in process, etc. will start to make sense and deliver great information to the improvement teams.

So for those who think that takt time does not apply to healthcare or administration, I respectively disagree.

Lean Blessings,

The Power of Kaizen

Image
                                                         Lean Nation, Today I want to talk about kaizen.  Kaizen is actually two words: Kai = change, and Zen = for the better. Taken together kaizen is change for the better.  In the spirit of continuous improvement, organizations use a kaizen event to deliver meaningful team-based change.   The DNA of a kaizen event is to apply an entire cycle of the scientific method in a compressed time.  A kaizen event is traditionally a 4.5 consecutive day endeavor.    Of note is some organizations run 4-5 teams in the same kaizen event so there is a small distinction between kaizen events and kaizen teams. The investment in personnel time and leadership time to complete a kaizen is not insignificant.  The amount of time, however, is not as cri...

Lean Measurement: measurement and target setting is simple

Image
  Lean Nation, Today’s blog is about metrics, lean metrics to be specific. Anytime we improve, we cannot validate we have improved unless we can measure a difference. But where can we expect a measurable change and how much of a change is considered good when studying processes? Having worked with organizations over the last 30 years, answering these two questions can be quite challenging, but it doesn't need to be.  When we struggle for a solution to these two questions, my advice is to always go back to the basics. In lean improvement, we are trying to get better performance from two activities, seeing (discerning) and eliminating wasted time and activity. If we eliminate wasted time and activity, what can we expect to find? Lean organizations understand that when waste is removed from a process three things will simultaneously happen: 1)       With less time being spent on wasteful activities, we should expect that the time to complete work should tak...

How to Draft and Publish a Book

 Lean Nation, This month we are going to deviate from our normal lean based topics.  One of the questions I frequently get is how do you author and publish a book. At the time of this blog, my fifth publication is currently in copy edit in anticipation of a fall or winter release. Truth be told, I was a math geek in high school. I dodged every English and literature class I could. I nearly failed first-year English class in college. So how did it get to the point that I have now published five books in a 13-year span? Probably divine intervention, but more seriously I have learned a few things along the way, and I would like to share them with you in this blog. I think everyone can author a book, but most people fail to get started. If you have a story, it should be told. Not to get rich to but to capture your thinking at a point in time. Once in print, your work is available for generations. So, with that introduction, let us review the key steps for consideration in writing ...
