MESA Part 3 – Delivering Value through BPM Workshops
This post continues the discussion of how to apply Business Process Methods to implementing MES based on the ISA-95 standard.
As you recall, we had to develop some material before holding consensus workshops. It goes something like this :
- Use the ISA-95 definitions for manufacturing activities and determine those performed
- Determine the strategy and objectives of top management.
- Develop an As-Is state in the form of a process flow for each activity
- Determine the shortfalls, issues, and requirements for each activity
This material provides the framework and focus for consensus workshops that will be held to determine how to both address identified shortfalls, and to reach the objectives of top management.
So, what do we expect to get out of the workshops? In order to develop a justification and plan for reaching the aforementioned objectives, we need some supporting material:
- To-Be Process – This is a process flow that has been modified from the As-Is process flow we bring to the workshop for each activity. Again, this is a high level flow that shows how the basic activities are performed and the information flows between different activities, systems, and resources. Don’t forget to put it down on paper. A textual description of the process flow goes a long way in clearing up the understanding of what’s going on. I usually put this into a companion document that accompanies the process flow.
- Systems Footprint – Although we’d like to focus discussion on the process alone, independent of which system performs each. As much as we’d like to believe we can start over and make everything work in an optimal way, it’s not completely practical. There are legacy systems that already perform some functions, and initiatives for new systems that will pick up other functions. Without getting into details, a high-level mapping of functions across existing systems will help to determine what the technical roadmap for implementation will look like.
- Business Case – Here’s where collecting those shortfalls in the As-Is state really pays off. If we assign an issues Champion to bring real-life examples of each shortfall, and an estimated cost per occurence, we can start to build a case for ROI. This goes a long way in addressing the savings and efficiency aspect of the business case, but we shouldn’t ignore lost opportunity costs. If we consider the revenue impact of reaching the objectives laid out by top management, we can calculate the impact of increased revenue as well. Consider the example in my previous post “MES for Competitive Advantage.” During our workshop, we should capture how the To-Be process will address the shortfalls and provide competitive advantage.
- Change Management – How a company addresses change determines how successful the MES implementation will be. It’s critical that a Change Management Champion, CMC, attend every workshop, capture issues requiring change in related functions, departments, and systems. The CMC will be a liason role that communicates the impact of the proposed To-Be state. It is critical that the CMC has the full and real support of top management. Change can be difficult and it will be important to identify areas of resistence, overcoming resistence, and determining the cost for change. In addition to determining the impact of change, the CMC will also identify those areas that will require either modification of training or additional training.
This is material that we develop during the workshop. It doesn’t have to be detailed or pretty. It does have to address the shortfalls and objectives, so keeping the conversation focused is important.
What workshops should we hold? The workshops should be organized at a level high enough to capture one of the major areas in the ISA-95 framework (for example: Quality, Production Control, Inventory Management, Maintenance, Procurement, etc). Each workshop will address a series of activities performed for an area. For instance, a Quality workshop might address: Test Definitions and Distribution, Testing Procedures (in-line, at-line, off-line), Material Review Board, MRB, procedures for rework, Quality analysis procedures). These are by no means complete, but they should address those areas where the shortfalls are significant and are critical to meet the objectives laid out.
Who should attend? Representative Subject Matter Experts, SMEs, that either appear on the As-Is process flow, or subject to change with the anticipated To-Be process. As much as manufacturing companies hate to commit these resources to these kinds of workshops, because they were hired to actually produce things, their participation is absolutely critical to the success of the proposed changes. Without their input and consensus, there will be resistence to change that is not always possible to overcome, and mistakes made in both requirements and implementation strategy that will be costly to remedy.
