Today we will talk about the three main methodologies to improve the capability of production processes:
- Relax tolerances thanks to concurrent engineering in the Product Development phase
- Reduce process variability through continuous improvement and Lean Six Sigma
- Shift the mean of processes through continuous improvement and the Manufactuing Capability Acquisition
Lean Six Sigma
Those involved in the improvement of production processes know how much Lean Six Sigma is the reference methodology in this sense. Without going into technical details, Lean Manufacturing, or Lean Production, aims to “streamline” processes by identifying, reducing or even eliminating waste within production systems and the supply chain, but not only. Just as to obtain sports results it is necessary to lose weight, in the same way it is necessary to eliminate all that is not strictly necessary for the flow and processing of materials and information in order to satisfy the customer by reducing production costs, the cycle times of semi-finished products and improving the quality of the processes.
On the other hand, Six Sigma gives its best when you want to reduce the variability within the processes. Variability is in fact responsible for the uncertainty associated with a company’s production system. A high uncertainty, for example, does not allow us to estimate costs, times and the amount of material needed with the necessary accuracy. High uncertainty in processes also means high probability of rejection, with a consequent increase in associated non-quality costs.
It is therefore clear that Lean Six Sigma is a necessary tool for companies with a view to continuous improvement. However, even if necessary, it may not be enough.
We have already described in a couple of previous posts the importance of concurrent engineering, i.e. that phase of product design that considers aspects related to the production, assembly and maintenance. In the concurrent engineering phase, costs and production times are defined.
By means of simultaneous design, in fact, the experts of the production processes are involved in order to prevent problems in the subsequent production ramp-up phase.
As can be seen in the following figure, according to some estimates, the design impacts by 5% on Product Development costs, while it affects the costs associated with the entire life cycle of the product by 70%.
The final result will be a synergistic effort to arrive at the best possible design compromise, thanks to which many of the improvement activities (see Lean Six Sigma) can be avoided.
However, a good initial project and a structured activity of continuous improvement may not be enough, especially in the presence of innovative design products (geometries, materials, functionality). In this case, in fact, it may be necessary to acquire a new production capability.
Manufacturing Capability Acquisition
It’s possible to acquire new capabilities throughout technology scouting, looking for, identifying and selecting the best technology or the most suitable solution to reduce the gap.
Otherwise, it’s possible to do Open Innovation through collaborations between companies, technology transfer centers and universities in order to develop new production technologies.
Finally, if the company is properly structured, it is possible to implement a technological research and development department with the aim of developing new solutions internally.
In particular, in the presence of innovative production processes that do not exist on the market, the use of a Stage-Gate process is recommended. In this sense, the MRL approach is perhaps the most used.
Manufacturing Capability Management
These 3 approaches (Concurrent Engineering, Lean Six Sigma and Manufacturing Capability Acquisition) used in a synergic way, shape the Manufacturing Capability Management structured process.
Therefore, through this approach companies are able to manage their production capability by leveraging existing methodologies for improvement and technological innovation.
Where to start?
In this short post we have described the main approaches to improve the production capability of a company. This entails a series of rather evident advantages, starting from a better manufacturing quality of the manufactured articles, lower waste, lower costs and lower crossing times.
In this sense, Accialini Training & Consulting can provide the support you seek. In fact, we are able to advise you on the processes and methodologies to be implemented depending on the current state, budget and business requirements. Is it better to redesign a detail according to the logic of simultaneous engineering or better to make continuous improvement? Or, do we need to acquire new capability, and if so, which approach to follow? Check out our Manufacturing Capability Management service.
