Once a manufacturing process has been optimised to achieve its rated operating efficiency, the business focus quickly shifts from optimising the process to running it in production; irrespective of whether that process is entirely manual, fully automated, or somewhere in between.
All too frequently, crucial learnings are not recorded and the deep understanding of the process is lost.
Some processes that are running today are now so old that there is no-one left in the company who originally worked to optimise them. They might run perfectly well at the moment, but no-one really understands them. There is often little appetite from the business to retroactively gain a deeper understanding of these legacy processes because “it’s worked well for years, so why change it?”.
And therein lies the problem. Things do change, often unexpectedly, often outside of our control and sometimes drastically.
Customers change what they want. Governments change legislation. Businesses change strategy. Technology moves on. People move on.
It’s highly likely that you’ll understand the normal variation to the inputs and how to manage them to control the outputs. But what if something more critical changes?
If you don’t currently have a detailed understanding of how your processes operate today, how quickly will you be able to respond to major changes?
On the occasions when the knowledge of a process is well-documented, it tends to only cover the one process in isolation and doesn’t address the effect on those upstream and downstream in the entire end-to-end process.
For example, there’s no value in making one process run faster (e.g. cooking) if it makes another one run slower (e.g. cooling) and in-turn causes the entire end-to-end process to run at a lower efficiency.
There are also many instances where processes are not currently achieving their rated operating efficiency, or never have done. They are often run with sub-optimal output because no-one knows how to improve it – because there isn’t a detailed understanding.
As a starting point you could:
Only once your existing process has been properly understood can you start to identify the specific vulnerabilities and take steps to mitigate them. You can then ask yourself questions like:
The answers to these questions will likely lead you towards making several improvements, both big and small. These improvements should make the entire end-to-end process more resilient and make your business less vulnerable to major changes – whatever they might be!
42 Technology has a wealth of experience helping our clients in a range of industry sectors optimise and future-poof their manufacturing operations.
In one recent project we supported our client by carrying out an in-depth investigation into the extent to which some aged assets could be extended beyond their original capabilities to support a major evolution of the established product in response to changing customer expectations.
Particular attention had to be paid to aspects of the end-to-end process where any change would lead to requalification of the line, or where process reliability would be detrimentally impacted.
The result enabled our client to establish a clear roadmap to extend the operational life of the assets, supporting the manufacture of the new product variant with only low cost and low risk modifications required.
