Work Standards

Why do we have standards?

“Where there is no Standard there can be no Kaizen” – Taiichi Ohno

Not long time ago I was talking with a college about the reasons for unsuccessful lean implementations.  I shared with him this time on which after a very successful launch, suddenly everything stop working.  I had no idea of the reason until one day when talking with one of our managers with previous experience on a lean manufacturing environment he said, “you know what is our problem?  That we are using standards to make people accountable and take disciplinary actions if they do not”.

Standards are mean to be a guidance to ensure effective consistent work.  We cannot penalize our employees for making mistakes, that is how we learn.  Just like in our private lives we used symbols to mark our milestones and set our path to happiness, standards are tools to show us the current right way to complete a task in a such a way that we will satisfy our customer needs.

Standards are not written on stone, they are not static but dynamic, change over time.  They shall change because they are the baseline for continuous improvement.  Kaizen or continuous improvement is a lot about experimenting with new things, try something new and see how the outcome changes.  As managers we need to be aware that experiments are not always successful.  The real value is that we try something different, we did not accept something just because we always do it that way!

We need to use standards to set the right path to customer satisfaction and to inspire our employees to improve their process.  An employee who is owner of the process and actively participate from the continuous improvement process, is an employee who cares and therefore feels greater levels of job satisfaction.  With the right mentorship, our employees will be problem solvers, better professionals; and of course if they feel better by the time they get back home they will be better people as well.

Continuous Improvement, Kaizen, Work Standards

Why choosing the right metrics is important?

“What gets measured, gets managed”. ~Peter Drucker

There is no kaizen without standards, and we cannot establish standards without measurements.

Standards are required to efficiently manage the work areas on a daily basis.  Every time problems arise, managers should go to gemba to revise the existing standards, investigate what happened and identify the root cause for the non-conformance.  Sometimes, the problem is that there is no standard.  To be able to understand the problem and later on create standards we need to collect data of the current status and analyze it.  Why happened? When? How?  As soon as you answer these questions, establish a temporary countermeasure on the spot and then find the root cause.  If the real cause of the problem is not identified, if will happen again.  After the root cause identification standardize to prevent recurrence.

The three major kaizen activities are: standardization, 5S and elimination of muda (waste).  All three requires gathering some kind of data and analyze it to get improvements.  A lack of 5S can be considered a sign of inefficiency.  A good 5S program, on the other hand is very helpful to identify right away non-conformance situations and facilitate the stating point to start the investigation process.

Good measurements are critical for kaizen, they provide a picture of the current process.  Metrics needs to be aligned with the company KPI’s and easy to understand by the production floor employees. The metrics selection, their accuracy and precision are very important to the success of the continuous improvement activities.  Wrong or inaccurate metrics will lead us to take wrong decisions.
