A portrait of an angry driver sitting in his car.Have you ever been frustrated when booking in your car in for a service or repair?

Have you been put on hold, transferred multiple times or waited for a return call? Maybe you had to wait in a queue to check in? Worse still, your car wasn’t ready at the time it was promised?

That’s just the customer facing side of the business. Technicians are faced with an ever increasing array of vehicles fitted with more and more complex technology.

Stores and reception staff are also under pressure to accurately provide parts and information within ever decreasing deadlines.

Where do we start?

Although our garage is part of the service industry, the functions they perform can be described as a process. They may not be manufacturing but they are still using manpower, materials and machines (inputs) to make changes in line with customer requirements. We, the customer, judge their output in terms of quality, cost and delivery time.

Once we understand this, we can capture each process and improve it. I use simple process flowcharts like this one.

Many of the identified “problems” can be eliminated at very little cost by applying the foundation improvement techniques; 5S, 7 Wastes, Visual Management and Standardised Work.

Once the simple, low cost solutions have been implemented, garages can look at how best to utilise the opportunities offered by cloud based technology.

Take a look at the before (left) and after (right) shots of a repair workshop.

While the before shot may look quite tidy, the improved layout and visual locations created using the 5S technique, resulted in a 50% saving in technician time searching for equipment.

Improvements were also made in the time taken by each vehicle to go through the shop and a reduction in damage to parts removed during repair.

Using the same techniques in the car parks and spares stores resulted in improved customer experience, time to retrieve parts form stores and part availability.

Reception and customer enquiry experiences were also improved in time and accuracy by eliminating waste from the processes and creating standardised work procedures.

So for the investment of some time, paint, hooks and labelling machines, you can improve competitiveness and profitability at the same time as enhancing customer satisfaction in terms of quality and delivery.

Workshops of the future

I recently attended the Automechanika show and saw many examples of how we can use cloud based technology to further eliminate wastes in our garage services.

The example that stood out most was the vision presented by Autodata.

Autodata currently provide up-to-date technical information for over 29,000 models using a cloud based system. Can you imagine even having the hard copy manuals for that, let alone retrieving the one for the job? Even if you did, they would appear in different formats and be quickly out of date.

The beauty of their system is that other providers can develop applications to share the same platform. This will mean that the wastes incurred by accessing separate systems for bookings, queries, ordering parts and invoicing can also be eliminated.

This system will also link with your connected car. Once your car has communicated its needs, the system will automatically arrange the details and order the parts. Then the booking slot, cost and directions will appear on your smartphone. All you have to do is press “YES”.

I’m looking forward to this day, and who knows, perhaps my car will then drive itself in as well!

stopwatch“You should always be able to take out at least 50% of the set up time”, was the target set me by my master engineer from Nissan.

In fact SMED equates to changeover in less than 10 minutes!

Having already tried videoing changeovers and studying them with a team, this seemed like quite a tall order. However I was soon to discover there was far more to reducing the time than just looking for waste on a video.

In the last blog we looked at the benefits gained by improving your set up times.

In this blog we look at a structured technique and 5 tips that will enable you to halve the time your machine is stopped. These work whether it is an old press or the latest 3D printer.

 

The four step technique

Step 1: Capture the current situation.

Use a video to capture the whole changeover. Break it down into work elements and record them on a Standardised Work Combination Table.

Changeover time is defined as the amount of time taken to change a process over from the last part of a production run to the first good, repeatable part of the next production run.

Changeover Time Diagram (SMED)

The phrase “first good repeatable part” is important. It’s not unusual to find processes where the first part may be correct but subsequent parts are not. Or extrusion processes where changes in material or colour take a while to be purged.

Step 2: Separate internals from externals. Decide if each element is an internal or an external using these descriptions.

Internal Element – any work element that cannot be carried out safely unless the machine is stopped, e.g. tool changes, material alignment

External Element – any work element which can be carried out safely while the machine is running, e.g. preparation of tools, materials etc.

Now re-organise the steps. Put all the external steps either before or after the machine is stopped. Look how the red stop time decreases.

Step 3: Convert the internals to externals. This usually involves some physical change to the equipment allowing you to move yet more elements to externals.

Step 4: Eliminate the waste. Use the 7 Waste technique and the tips below, to further reduce the length of the red bar.

 

5 Top Waste Elimination Tips

1. Reduce the need to measure and make adjustments. Aim to pick and place tooling into the exact location, first time. Use:

  • Block gauges.
    • 1 fixed datum point.
    • Colour coded location lines, or match marking, for different tools.
    • And configure and label setting gauges.

2. Simplify and standardise the tools used.

By standardising the tooling dimensions, we could use tools that fit instantly instead of having to use adjustable tools.

3. Bolts should be treated as the enemy!

  • Rigorously eliminate them. In this example we used 1 quick release catch instead of 2 screw fastenings.

Eliminate bolts for quick release catches

  • Make sure any remaining bolt heads are a uniform size. This reduces the time it takes you to search for and pick up different hand tools.
  • If Allen keys are used, weld them into position. This saves you handling time.
  • If bolts are the only option, ensure that the bolt length is reduced to the working minimum.

4. Avoid using cranes and hoists. They are slow.

  • Use tables or scissor lifts set at the access point height. Prepare as an external.

5. Always keep a good 5S standard. External preparation, configured tooling and clean equipment all save time during the set up.
