Organisational Agility

“…every dollar we spent on agility has probably got a 10x return on every dollar spent on forecasting or scenario planning.”

A statement by Marc Engel, the Chief Supply Chain Officer of Unilever Europe, in the article “Agility Beats Forecasting when the Supply Chain is Stressed

This is how Tom prepared for the arrival of Covid-19. Well, he did not know Covid-19 was about to arrive; it was not part of the scenario planning; the forecasts showed increased demand. When iCovid-19 appeared on the radar everyone said not to worry.

Tom was however familiar with daily disruptions: sales not matching forecasts; supply problems; attendance issues; machine vagaries; load shedding and who knows what else.

Tom understood that to create a new “plan” that took the changes into account that the factory would need to be able to reschedule frequently and then get the factory to work to the new schedule.

Tom saw that the process of obtaining data, rescheduling, and issuing schedules was far too slow. Staff were doing their best, but it required substantial manual effort to try and switch to new schedules.

They tried stock buffering as a way of reducing the need for rescheduling; occasionally trapping raw materials in the wrong sales unit as well as incurring obsolescence as a result of sales not matching forecast or due to shelf-life expiries. Buffering did not work as well as expected.

To cater for the uncertainties of his world Tom digitalized operations. Not just randomly, with an IOT here and an IOT there, but with the specific focus to achieve the following

  • To make data available within the system, for use in decision making, current and trustworthy.
  • To shorten the decision-making process so that the factory could react faster to “unexpected learning opportunities”.
  • To be able to publish schedules more quickly to all departments / staff (and suppliers) who could be affected, to ensure synchronized execution.

Everybody has a plan until they get hit”

How quickly can you recover?

Customer service, productivity and profitability are up. Covid-19 is just another day in Tom’s world.

The Role of Advanced Production Scheduling

To be able to make decisions more quickly Tom required a scheduling tool that would

  • Take minimal time to run – It needed to generate an actionable schedule in seconds.
  • Generate a schedule using their rules and considerations
  • Offer “drag and drop” and rollbacks.
  • Facilitate and store what-if schedules to enable comparisons between schedules.
  • Be easy to understand and use, with easy use of colour to help understanding.
  • Be able to work with their current and future systems.

After evaluating various alternatives Tom selected the Siemens Opcenter APS solution, as it met the above criteria and could be configured and extended to meet their needs.

To ensure schedule integrity, Tom understood that the schedule would need to access data that was both correct and current.

Tom used the issues encountered when generating schedules to drive method and procedure changes in supporting areas.

Often these changes required the introduction of new technology e.g. they needed to implement a shop floor feedback solution to ensure that the system contained the current status of jobs in progress in production, for use by the scheduling solution.

It was interesting to note what an impact improved scheduling had on the business, with initial payback only taking a few months.

Pressure was exerted on the procurement department and on suppliers to provide feedback to support decision making,

Improving and keeping data accuracy was a key focus in all areas.

Once they had an agreed schedule, they could issue it in seconds, via electronic means.

Being hit by an unexpected change was often painful, recovering was not fun and often included heavy breathing sessions. Over time it got easier to do.
