Toyota way (Part 2)

Let’s discuss about the second pillar now.

Continuous improvement involves three principles: Challenge, Kaizen, Genchi genbutsu.



I think this is what keeps Toyota move ahead of its competitors globally. If these practices are followed religiously, it will make wonders in any company. I call this as a culture to be created and followed.

 Many of them complain that although these are the best practices, why there was a mass recall of cars and labor unrest at Toyota’s manufacturing plants.

 The answer to this question lies in the question itself. These are best practices only if followed. It is as simple as that when a company as big as Toyota and the originator of these practices doesn't SUSTAIN them, it is bound to fail and to be noted that not only Toyota but any other company too fails if it doesn't respect its principles.

Challenge:

Everyone take up challenges. Sometimes we achieve them, sometimes we can't and other times we will change the challenge for better or reduce its priority as it is difficult to achieve. It is the same in running a company but with necessary backing and more stringent plan to achieve the target.

Let’s take up an example to understand this well.

I run 5 km every weekend.


I started running a year ago. When I ran the first time, I took around an hour to complete the task. I didn't have a challenge then. My aim was to complete 5 km and was not time bound. After which I decided to have a target and that was to run in 15 min which was close to impossible. Is it even a realistic target?

This is the same mistake we do at our work too. The targets should always be SMART and not superfluous.

Specific
Measurable                                       
Achievable
Realistic
Time bound

Without knowing our target, it is difficult to understand where we stand and what is necessary to achieve the target. In production terms, we call the target as Standard and where we stand now as Actual. The difference between the two is called as Gap/Abnormality. Unless we understand this, we will never be able to identify problems. After all Toyota way is all about problem solving.

(Note: I have found that many companies don't know what their actual is, it is very important to grasp the actual data, I’ll talk about this in KPI- Key Performance Indicators monitoring in the later posts)

In my example, my actual is 1 hr to complete a 5 km run and my standard is to complete in 15 min. Let me analyze this target setting in a SMART way.

1. Is my target Specific?
Yes, a run to keep myself fit.
2. Is my target Measurable?
Yes. 5 km run.
3. Is my target Achievable?
It’s very difficult.
4. Is it Realistic?
Not very much.
5. Is it Time bound?
I don’t know by when I want to achieve my target.

So after making an analysis on this, I got to know that 15 min is very ideal. I had to set a realistic target now. I practiced for a few days and took sample data over time and fixed the target as 25 min (A minimum of 6 months data is desirable in production/services).

 This was more realistic and achievable and I set 6 months as the time to achieve this feat which makes it time bound. I made a week by week target plan to achieve my standard. Now, I was more determined to achieve weekly targets in order to win the challenge (Small continuous improvements over time).

After 6 months, I ran in 24 min 32 sec. 


I was happy about this and then I stopped running for the next six months (I was lazy J). Now, I want to change the standard to 20 min.

I want to do PDCA in this activity before going for the new standard. PDCA is important at every stage of an activity. (Thanks to Shewart and Deming for teaching us this beautiful concept)

Plan to run 5 km within 25 min.
Do the running; I took 31 min 16 sec (This is what happens when you don't sustain, things can get really      
      worse).
Check against the target. A GAP of 6 min 16 sec found.
Act upon this.

My first target is to achieve my best. This is called Occurrence type of gap analysis (Every day there will be one or the other abnormality in the production line, this leads to the occurrence type of gap. We must eliminate this before going for a new standard. For ex: If efficiency target is 95%, and we are able to achieve 90~92% over a period of time. We must first achieve 95% consistently and then go for a higher target).

Once I achieve my best i.e. 25 min, only then will I be able to go for the new standard of 20 min. This is called Setting type of gap analysis (Once we eliminate or minimize the occurrence type, then we can go for setting type of gap analysis in production and achieve result. In the previous example, after achieving 95% consistently, we should aim for higher target).

Solving the occurrence type and maintaining it is called Sustenance. Solving the setting type and meeting the new standard is called Improvement.

The activity done to achieve both is called Kaizen, which we will discuss in the next topic. Before going to the kaizen section, I want to touch upon another topic called hoshin kanri which is very much linked to challenge.

Hoshin Kanri

Ho- Direction
Shin- Needle
Kan- Control or channeling
Ri- Reason or Logic

For a company to know its goals and work towards it, we need a direction and should control our movement through a strong logic to achieve the desired result. Just like how we need a compass to guide a ship in an ocean to reach our destination (Hoshin) and a good captain to take us there (Kanri).

Hoshin:
To set and prioritize mid to Long-term Management Plans and Annual targets, while engaging all levels of the organization to clarify their own targets and strategies.

Kanri:
Drawing up Problem solving strategies, constantly implementing them, checking for results, if not achieved adopting countermeasures

This is a detailed vision plan to achieve the results. The example I quoted about running previously was related to just one person. This is the main tool we use to break up the vision and set targets (Challenges) to each department and then to each group and then to every member in the group. In this way, every member contributes to achieve the company Hoshin.


A collective plan for the whole company can be done by following Hoshin Kanri, more information can be obtained online and in need of any clarifications, you can contact me.


In the final part, we will discuss about Kaizen and Genchi Genbutsu.
