The systematic collection and analysis of production data helps answer some of the most fundamental questions in manufacturing industry: What is the real capacity of our production plant? How is our production going per machine and as a whole? Are we ahead or behind schedule? How many interruptions have there been in our production, on which lines, and for what reason? And also: which products are the most profitable for us?
Answers to these types of questions are not only of interest to floor-level staff, but also to sales and management. This information is crucial, for example, because it helps target and proportionate sales activities so that the available capacity at any given moment is optimally sold to customers – neither too much or too little. Management is also interested in the data to support decision-making on recruitment and investment, and to monitor and improve overall profitability.
To avoid raising the threshold for collecting and using production data too high, the practical work should be made as easy as possible. Motivated staff, the use of automation, and starting development from a realistic level appropriate to your situation will help.
Data collection cannot be done without production staff, and on the other hand, floor-level staff also benefit from the collected data in many ways. It is therefore worth explaining to production staff in a practical way what information you want to collect on production, why, how, and how it benefits their work.
For example, when operators acknowledge disruptions and inspection tasks in an agreed and consistent manner, production runs more smoothly, and inconsistent disruptions are reduced. Motivation is enhanced by making it clear to staff that the company is interested in these issues, that they are getting the support and guidance they need, and that the collected information is actually leading to improvements.
The aim of collecting and using production data is to facilitate the work of staff, not to increase it. It is therefore worth automating data collection as much as possible. The basic data can be collected from device logics, sensor-based or manual workstations.
A production management system processes the collected data, and helps manage the internal production chain. At a later stage, automation can also be increased through integrations, for example with production planning and maintenance software.
To keep the threshold low, it is worth starting with the information that is readily available in your plant. There is time to improve the level of accuracy later on. Improving the reliability of the parameters in use is already a good milestone.
Targets should be kept modest at the outset, for example, acknowledging the cause of disruption can be agreed for all outages of more than five minutes. It is also worth focusing on the metrics that are relevant to each job role, are unambiguous, and which the individual employees can affect through their actions.
Optimally, daily work is both the starting point and the destination for collecting and using production data.
