Constraint-Analysis
Analyzing efficiency and improving supply chain processes
Our constraint analysis uncovers the root causes of inadequate results or perceived weaknesses. If necessary, we follow your supply chain from your suppliers through your organization to the customers.
We identify bottlenecks in your organization, business processes, or material and information flows and analyse them through cause-and-effect chains.
We reach the core problems.
Supply chains represent a network of machines, materials, transportations, processes, methods, customers, suppliers, employees and business rules, whose interaction is often obscure, always complex, so that results often do not meet expectations or requirements.
But how can efficiency be increased? How can the core challenges be identified?
The result of the constraint analysis is a so-called reality tree which shows the cause-and-effect relationships between identified symptoms and the root causes.
These trees represent the critical points from a technical and organizational perspective that slow down the performance of the overall system.
These weak points are then targeted and resolved .
The starting point of the constraint analysis is always a significant and subjectively perceived, or better yet, an objectively measured problem. Some examples are:
The Service Level is lower than the targeted service level of 95%.
Inventory turn rates are too low or there is too much inventory on items with high inventory ranges.
The lead times of in-house production are higher than required.
The service level of suppliers is too low. The resulting security mechanisms, e.g. safety margins, increase costs.
Daily shopfloor meetings to prioritize production orders as well as missing parts lists become the leading managing tool.
The quality of manufactured parts has declined, scrap rates and costs are increasing and the ability to plan is decreasing.
WHITE PAPER
Efficiency analysis and improvement of supply chain processes by constraint analysis
The constraint analysis is an element of the Theory of Constraints developed by the American-Israeli physicist Eliyahu Goldratt (1947 - 2011). The Theory of Constraints became known through his bestseller book 'The Goal'.
The Theory of Constraints says that a managable system grows until one of its parts as constrained. If this constraint is found and eliminated, the system again grows until the next part reaches a constraint.
In the gearbox production of a large automotive supplier, Abels & Kemmner consultants succeeded in increasing the production throughput by 10% by means of a constraint analysis without having to invest in capacity expansions.
Abels & Kemmner has had the best experience with constraint analysis of supply chain processes for many years. Our experienced consultants ensure the quality of the analyses and concepts. Of course, we are also ready to implement the results in practice. The effectiveness of the defined measures is shown in detail in the reality tree, the question of blame and responsibility is nowhere raised, nothing must be hidden or swept under the carpet.
