Although it can be difficult to stay positive during uncertain times, those business that hope to survive must look beyond the current crisis and focus on those things that do remain in their control. One way to do this is to apply the five lean manufacturing principles.

“There is a saying that goes ‘when fishermen cannot go to sea, they mend their nets’. Likewise, business owners and manufacturers should now do the same by using their time to transform their businesses, not just to survive the current storm, but also to look to the future,” says Marten Stavast, Senior Industry Expert in Manufacturing at GroFin, an impact-driven SME financier. With manufacturing having been one of the worst-affected industries, he reminds us of the lean manufacturing principles:

1. Define value

Any entrepreneur will agree that the customer always comes first. Lean manufacturing takes this idea beyond customer relations to also put the customer first in the production process. The true value of any product or service is defined by what your customers are willing to pay for it. Your product may seem valuable to you because of the time and resources that went into creating, but its value is determined from the point of view of the customer.

Lean manufacturing begins by determining the needs of the customer. Interviews, surveys, demographic information, and web analytics are some of the tools you can use to determine what your customers want and at what price they can afford it.

2. Map your value stream

Once you know what your customers want and value, you can map your value stream. Use your customer’s value as a starting point and identify all the activities that help to create this value. The goal is to ensure that every activity in your production process adds value to your customer and can be delivered at the price point they want. If an activity does not add value to your customer, it is a waste. If you cut out any unnecessary processes that do not add value, you can reduce production cost while ensuring your customers still get what they want.

3. Create flow

Now that only necessary and value-adding activities remain in your value stream, you should ensure that each step flows smoothly to the next. Interruption and delays in production are no different to waste. A delay is more than just a bottleneck when one production step waits on another – it is any step that takes longer than it has to. You can improve the flow of value-adding activities by breaking down every step of the process and reconfiguring it as efficiently as possible, levelling out the workload, and training your employees to be multi-skilled and adaptive.

4. Establish pull

Stock sitting on your shelves or raw materials piled up in your warehouse is one of the biggest forms of waste in any production system and often places a big drag on cashflow for smaller businesses. This is even more true in the current environment.

A pull-based production system means that you only produce products based on the needs of your customers and only at the time and the quantities needed. Strive to limit your inventory and work in process items to only the materials needed for a smooth workflow. This approach requires ensuring some flexibility in your production process and the current environment, it might just give you the edge as a small business.

5. Pursue perfection

The final step in implementing lean manufacturing is by far the most important. Lean thinking should not be a once-off exercise that you complete now, while times are tough. It should become part of the culture of your company in such a way that every employee strives toward perfection and constantly getting better at meeting customer needs and reducing waste. This will not only set your business apart during times when customers are themselves under financial pressure, but also when things improve.
