13 Questions Reveal the Benefits of Manufacturing Execution Systems
By Conrad Leiva, International Board Member of MESA International and member of MESA’s Technical Committee
Doubting the potential benefits of a new Manufacturing Execution System (MES)? Perhaps you need to take another tour of your facility and interview people with some of these questions in hand. Here are seven key questions:
1. Has a product quality problem affected the last unit produced or the last eight hours of production?
2. Are we delivering to the daily production schedule? Can you tell?
3. Is the problem identified by routine tests at every shift change, or by an alert operator?
4. Does the situation only occur when a specific product or product grade is being produced?
5. Do all units, lines, or pieces of similar equipment experience the same issue?
6. How are you measured and what KPIs/metrics matter to you?
7. Are there wasteful steps identified in the AS-IS business processes?
A problem or inefficient process typically impacts multiple departments and individuals in terms of time, materials and, ultimately, dollars. Representatives from operations, business management, support organizations, suppliers, and customers should be interviewed.
Through this process individuals will be identified to represent each of these stakeholder groups on the core team. These interviews must capture the complete picture, including the short-term impact of the current state, the long-term impact, and the worst case scenario if changes are not implemented. Some areas of consideration include any potential health and safety impacts to employees or the community, and/or the risk of failed compliance to governmental regulations or customer standards.
Additional questions may include:
8. How is the situation affecting the entire manufacturing process?
9. What ancillary activities are being performed as a result of the problem?
10. Does one department adjusting a recipe to compensate for an equipment or raw material issue potentially disrupt downstream processes?
11. How much product has been produced out of spec?
12. Does this result in scrap or a downgraded product?
13. How much material, machine time, and labor are wasted?
In addition to identifying the issues or “pain points” experienced in the plant, it is also valuable to follow a Lean/Six Sigma approach starting with a Value Stream Map (VSM) of the process to identify non-value added steps that may be removed by automating or through the implementation of a MES/MOM solution. Through the VSM process, areas can be identified where waste occurs.
