The “basics” is the part that many people miss, skip or sometimes just forget. It is a good idea to sometimes, just sit back and relax. Then think about the basic rules and guides of what you’re busy with.
Business principles are very much the same as Personal lifestyle principles. Business decision-making is a little more structured, but the principles are the same.
We all make decisions on a regular basis, every day of our lives. Sometimes without even thinking about it. We can use examples such as: What time to wake up in the morning?, What to eat for breakfast?, What clothes to wear?, the list goes on…..
Production and Inventory Management normally starts with the question, What do we need? This is normally what we describe as “Forecasting“. Now, forecasting is exactly just that, Forecasting. Forecasting, like many other tools we use in business, is an aid for decision-making and is not law. We will talk about “Qualitative ” and “Quantitative” Forecasting in another post. Remember that things change. Be flexible.
The next question: What do we have?, is where we need to have processes and principles in place to control our inventory to have, in our supply chain. We should always strive for least investment in our inventory but also at the same time always being able to meet our customers expectations.
Now, if we are a manufacturing concern, we can not forget that we have to have proper Manufacturing Resource Planning and Controls in place. We need to make plans for short-term, medium-term and long-term, known as the time-span. Long-term includes facilities, equipment, products and processes. Medium-term includes production rates and inventory levels. Short-term includes day-to-day operations, scheduling, dispatching and monitoring.
How do we know what to make and when to make it without any communication. This is where we have to make sure a valid master production schedule is in place through our Sales and Operations Planning communications. We need to make sure using the correct Manufacturing Strategy principles once we know what our customers need.
Now that we know what our customers needs are, when they need it, what we need and how we are going to make it all happen, we should start by our Materials Requirements Planning. Also known as MRP. First we have to understand the differences between “Dependent Demand” and “Independent Demand” items to make sure that a possible materials plan is in place.
Once we’ve got our materials plan, we should concentrate on our “Capacity Requirements Planning”. We need to know what the difference is between available capacity, required capacity, theoretical capacity, rated capacity and demonstrated capacity. With this goes the understanding of efficiency, utilization and productivity. How all of this work in a manufacturing environment will be discussed in detail in another post.
The next step is the execution phase of manufacturing, planning and control. This is where we distinguish which control system is best to use for our shop floor control that suit our business profile. We will discuss pull-systems versus push-systems including the concept of “KanBan” and “JIT” at a later stage.
We need good quality business partners as our suppliers of raw materials and all other parts and goods that is not part of our manufacturing concern. To be able to get this process under control is to set up one of the most important departments in our company namely Purchasing and receiving. This is now where we have to make sure that proper business procedures and processes are in place to accurately select and actually get involve with the rest of the company, to know their needs and to be able to choose the correct supplier for the specified needs. Make sure we set up a proper flow diagram suitable for our purchasing cycle.
How are we getting our products to our customers in the best, soonest methods as possible. This is now where we need proper packaging, identifying, storage and moving methods, systems and processes. We will discuss the various modes of transport and right categories of carriers available in a separate post.
While we are working through the various categories and business models, we need to make sure that we carry out the 5s strategies together with lean manufacturing principles under the guarding eye of our Total Quality Management System
