Across the world, the Manufacturing Companies are leveraging Industry 4.0 to become more efficient and to deliver more to the Customers. Indian Manufacturing Companies have a long way to go. I heard a Multi-National Company say that they are in Industry 2.0 or 2.5 in India while their Global operations are going strongly towards Industry 4.0. This is the status of many Indian Manufacturing Companies.
To become receptive to Industry 4.0, Indian Manufacturing needs to lift their game in several areas. Majority of Indian Manufacturing seems to be stuck with traditional methods of working. Whether it is handling Quality or Maintenance or Industrial Engineering etc.
Some of the Companies are finding the need to change and adapting better methods. But, still majority of the Companies are still in a very ‘Lazy State’. It is not just about the Staff and their knowledge. It is about the perspective of the Management itself.
The Companies from Automotive Industry in India are in slightly better positioned as far as the Systems are concerned. But, even in this industry I observe that only about 25-30% of the Companies are having Good practices. 70% of Automotive and Auto Ancillary Companies are still working inefficiently.
In the next few Posts, I would like to discuss about a few areas in which the Indian Manufacturing Companies have to lift their game so that they can get ready for the Fourth Industrial Revolution!!
Let us talk about Maintenance of Plant & Machineryin this Post.
For ease of discussion, we will address two types of Situations.
I. Where the Traditional Machinery forms majority of the Machines in a company: Most of the Indian Manufacturing Companies have Traditional Machines with least amount of Automation.
The Maintenance that happens in many of the Companies is only ‘Breakdown Maintenance’. The whole Maintenance team would be attending to Breakdowns.
The Companies are dealing with:
- Multiple Breakdowns of the same machinery.
- Serious Production losses.
- Preventive Maintenance not happening regularly. (Production does not release the machines for PM!)
- Companies replacing the Machines in frustration and when pushed by the Customer!
- The Spares required are not stocked in many companies. In some companies you have Costly spares that are rusting. You never have something what you want.
Mindset of Maintenance Team in these companies: The Maintenance Team are busy chasing the Breakdowns. They are ready to burst if you just tap them on the shoulder!! They are frustrated with the Multiple Break downs. A good number of them are not ready to listen to any ‘Different approach’ as they are ‘suffering’. Their Bosses are ‘scared to touch’ them as the Basics may suffer!! The Bosses keep humoring the Maintenance team much less challenging them to get to new level!!
Lift the Game
I suggest following steps to lift the Game in Maintenance of the Traditional Plant & Machinery.
01. Strengthen the Maintenance team: If Breakdowns are too many and Maintenance team is under frustration, you can look at strengthening the Maintenance team by a) Training them b) Adding some Young Engineers to the team. Please do not fuss over this. You will more than recover your investment.
Differentiate: Even while having Break downs in a Factory, there will be at least 50% of your Machinery that is simply not having any Breaking down! These are ‘Zero Breakdown’ Machines. This may be due to your pattern of usage or may be these machines are built with generous Specs!! The Machines that have Zero Breakdowns have to be dealt differently. The approach has to be more Proactive to keep them as Zero Breakdown machines for a longer time.
If you don’t differentiate, you would be waiting for them to Break down and only then you will do something! Does not sound alright. Isn’t it?
02. Improving the machines: A proper Study of the Break down data for the last one year will help you understand why Breakdowns are happening and what you need to do to reduce them. The Corrective actions would involve things like a) Taking a few machines for major repairs b) Training users for handling the machines in a better manner c) Training the Maintenance team to reduce MTTR.
The approach here should be that of a Project approach. The Worst 10 machines should get out of the ‘Worst’ List in 4 months’ time! You need to rev up your Engine to get out of a big Pot hole that you got yourself in to!!
03. Lift the Perspective of your Team: You need to Train your Team and take them to companies where the Maintenance Practices are at the next level. This will help them to know about the next level of Maintenance Practices. Otherwise, they may not simply know the possibilities!!
04. Introduce Predictive Maintenance practices: Introduce Predictive Maintenance for machines that do not have Breakdowns. Many companies have belief that they should deal with the Break downs and then finally go on to the Better Maintenance Practices! It is not needed to wait! When you Train your team and take them to Bench Mark companies, the urge to get to the next level will start.
05. Have Targets for progress: Motivate the team and set targets for Reducing Breakdowns as well as expanding the Predictive Maintenance! Please ensure your team continuously visits companies that are doing better on Maintenance. Whether in India or outside!! Seeing is believing!!
II. Where you are dealing with Automated Factories: Many Indian Companies have introduced Automated Machines. Some Companies have set up Plants that are predominantly automated.
The Companies that have some Automated Machines or one/two Totally Automated Plants deal with issues like this:
- In many Cases, the Breakdowns are higher than the Manual machines!
- The Plant is not giving designed output. Sometimes the output is 60-70% of the Standard output!
- There are higher Quality Problems in these Automated machines.
- The Maintenance practices recommended by the Manufacturer of the Machine / Plant are not followed as they are ‘too costly’.
- The Maintenance team is not fully conversant with the Machine/Plant.
This status is not universal. There may be some Companies who are doing well in Automated Plants. But, a great majority of Indian Manufacturing is not in good shape.
Mindset of the Maintenance Team: The Maintenance team is still in awe of the Automated machine. They approach it in the traditional manner i.e Wait till it Breaks down and then attend to it. But, as this is an Automated machine with high output, the losses are higher! The Maintenance team finds out many short cuts with which they can manage the machine. Read it as ‘By passing most of the controls on the Automated machines’.
We keep approaching the Modern Machine with Traditional Mindset. The mis match can not give good result!
Lift the Game
01. Train the Team / Introduce young blood: You need to train your team immediately in Modern Maintenance practices. It would be very useful to introduce Fresh Engineers in to the System and give them bigger role in the Modern Maintenance. They don’t have ‘Experience’. So the acceptance is much easier.
02. Work on the System: In a highly Automated Environment the thin line between Maintenance Engineers and Production Engineers should be wiped out. Both skills are needed in the same Engineer. The Engineer should look at the machine as something that he has to maintain as per some Guidelines. Earlier he only had to ‘push’ the people in the less automated environment to get Production. Now, he has to deal with some disciplined way of maintaining the Machine. His attitude has to become more disciplined!
03. Use the Machine features: Most of the Automated Machines have a number of features that can be used to Maintain the machine. Collaborate with the Machine Manufacturer and use all these facilities.
There can be a number of outputs in the PLC that you can use for a Visual Management of the Machine.
The Predictive Maintenance can be introduced with a combination of Man and Machine.
04. Beats in the Shop: The Engineers should have a ‘Beat’ (Or Route) just like a Sales person in the field. During this ‘Beat’ the Engineer should check various features of the Automated Plant and ensure things are working as they should. The work of the Engineers should comprise of several ‘Beats’.
In a Traditional environment the work of the Engineer is predominantly dealing with the People.
05. Understand the Machine deeply: The Automation and the Automated Machine/Plant has to be understood deeply. How the machine works and what are the indications of the Machine asking for attention.
A Lot of Data has to be collected and the patterns have to be understood.
06. Digital Twins: When you understand your Machine / Plant, then you can take the help of the Industry 4.0 elements and take it to the next level of making a Digital Twin of the Machine. Then, you can predict failures and prevent them much more effectively.
The approaches can differ from company to company. But, some of the fundamentals will remain same for everyone.
We need to find a way to lift our game and graduate to Industry 4.0.
Will your Company rediscover itself during this Industrial Revolution OR are you going to miss it out totally?
There is a good buzz in the Indian Manufacturing Industry now about Digitalization and Industry 4.0. Every Managing Director would like to tell his/her colleagues at the Club about how they are implementing Digitalization in a big way and trying to implement Industry 4.0 and so on.
I hear many Functional Managers also trying their hand at collecting more data from machines. They are not very clear what exactly they want to do with that data. But, they have started a Project anyway.
This same companies are having modern Machine Tools that already collect a lot of data as a routine. Most of this data is not being used at all.
The other day I heard about a Machine Shop Manager who is collecting data about vibration on the tool holder on the Machine tool and trying to decide when to change the Tool. This is a smart local application. This Will definitely help the Manager to avoid Quality losses due to blunt tools running for more than their life.
But, these smart local applications are very few.
Irrespective of what they already have, Managers and Managing Directors across the Industry are in mad rush to get a tag of ‘We are implementing Industry 4.0’.
I see following problems in many of these companies rushing to ‘try Industry 4.0’.
01. Many Indian Manufacturing Companies have not yet implemented the Basic Lean Practices in their Shop floors.
02. The Pull principle is not being used. There are many companies that are still having Batch Production on their shop floor.
03. The Layouts are still archaic that necessitate unnecessary movement of material.
04. I have seen companies allowing excess Production as they do not want their workmen to be idle!!
05. There is no focus on the Skills of the Workmen. With the attrition problem on the Shop floor, this is a serious problem for the industry.
06. I know many companies that have not solved some perennial Supply issues and resultantly produce according to what material is available and not what Customer wants!
07. Wherever the Companies have installed Automated Machines and invested in to Technology, I have seen that the Company is having more problems with the Higher Technology machines. The Quality losses are higher in these machines, they breakdown more and over a period of time many of the wonderful features of these machines are by passed and it is used worse than its’ less Automated cousin that is co-existing.
This is not a complete list of problems. I am not saying there are no Companies that are not using Technology and Lean Principles. But, this is a very small percentage.
I see three issues from this situation:
a) Understanding Lean approach: Majority of Indian Companies have still not understood and leveraged the Lean Principles.
b) People element:We have not understood how to address the ‘People’ element when we bring in higher Technology. We need to help the person involved to ‘Work differently’.
c) Short term approach: We are still looking at this year results and many of us are worried about this Quarter performance and this Month’s performance. We continue to remain ‘Short Termish’!
While this is the status, there are some companies that are waking up as the Market Competition is increasing and they can’t simply tolerate the HUGE inefficiencies on the shop floor.
Every Company has to wake up!! If they are not woken up by the ‘Indian Competition’ then they will be woken up by the ‘International Competition’.
The Other Side
While this is the status of majority of the Companies trying to implement Industry 4.0, the Companies offering ‘Industry 4.0 solutions’ are also in the same Boat! While there are some International Companies like Siemens and a few of Local Companies that have understood how to use Industry 4.0 elements to take their clients to the next level, majority of the Companies offering the ‘Expert services of Industry 4.0’ do not know what they are talking about!
I have personal experience of talking to a few of these experts who have fancy websites calling out the World to implement Industry 4.0 with their help. Most of these Companies have not done anything in this area. Most of them do not know anything about Lean!
So, we have a very dangerous combination of Companies who are not ready for Industry 4.0 but want to implement it anyway! On the other side we have a big contingent of Companies who do not know anything about Manufacturing offering Industry 4.0 solutions. A lot of money is getting wasted around!!
How can we go forward?
It does not matter what the current status of the Manufacturing Company is, if they have understood the need to improve their efficiencies and the power of Lean then we can progress.
I would suggest that these companies take up a Re-Engineering of their Manufacturing that would involve the following:
- Put Three Year Targets like:
o Tripling People Productivity (Blue and White Collar Please)
o Cutting Quality Losses by 75%.
o Cutting Manufacturing Costs by 50%
o Solving 100% of Customer related problems permanently
You can formulate a few more Goals that are relevant to your company.
- Only a BIG target will wake up your Company and your team! You will achieve it!
- Formulate a Full Time Task force which can be filled with Young Engineers straight from College. Bring in technical experts as needed. But, having a positive mindset is more important than the Technology.
- There should be representation from every Function in this Task force.
- Educate their Employees on Lean Principles starting with the Top.
- Recast their Value Stream Map on the basis of Lean principles.
- Resolve the perennial problems like Material Shortages, Bad Sub-Contractors who do not deliver on time and so on, Perennial Quality Problems that have become as permanent in the company as the owner himself/herself!
- Formulate several Projects that should be championed by the Task force with help from the regular Teams.
- On the way at the right time, we should start educating the employees on Industry 4.0 and the Technology that is available.
- Visiting International companies to understand the Lean principles in action or Industry 4.0 in action is a very good idea.
- Implement Industry 4.0 elements as needed to achieve the Three year Goals. Finance Head should ensure that there is no Project that is being done just for the fancy of it. Every Project should pay back handsomely.
When you are achieving some BIG targets in 3 years, that will allow you to spend a good amount of money to achieve it. The problem of how to finance the Industry 4.0 Projects will be addressed.
So, you can turn your weakness of ‘Low Efficiency’ and ‘Not having implemented Lean’ in to something more positive as it would help you to spend good amount of money as you will get the payback relatively easier.
So, when will you start off?
Improve your Profits significantly and become a genuine implementer of Lean and Industry 4.0!!
