MRP is a resource and planning tool that is forward-thinking, and time-phased. The philosophy of JIT, on the other hand, is based on the riddance of waste. This analysis can be greatly misleading. Generally, in MRP, there are two basic information types that are required:
BlockedUnblock FollowFollowing Learning agile while practicing. I try to be the best version of myself, as often as I can. I recently ran an Introduction to Kanban training session for my work colleagues.
I have started with Kanban origins, talking about how Toyota started studying supermarkets and customers shopping behaviour in supermarkets. Toyota used supermarkets as an inspiration in their quest to improve manufacturing processes by eliminating superfluous inventory They observed that customers generally purchased what they needed, when they needed it, knowing that the future supply was assured.
Conversely, supermarkets stocked up on only what was expected to sell.
Demand from the end customer passes up through the supply chain. Kanban uses this rate of demand to control the rate of production. Simplistically, the process works as follows. Distribution pulls an item from Manufacturing.
As it gets pulled, a card from a Kanban table is attached to the item. Consumption pulls an item from Distribution. The previously attached card is removed from the item and returned to the Kanban table.

May 7, Dear Gemba Coach,As I read lean posts and papers, no one seems to have problems like this anymore, but I am trying to convince my manager that we have a bottleneck in the production process and that we should have two work stations in parallel to improve the flow.|

At this point, one of my colleagues asked me: Which came first, Kanban or TOC? Then came the subsequent question: After-all, I thought that I was only on slide 12 of 65 and time was marching on.
After the session I felt though that these were some really interesting questions which deserved a better explanation; I should have elaborated more.
This write-up is my attempt to address these questions better. So, which came first, Kanban or TOC? This is an easy answer, definitely Kanban. In Toyota applied this method in their main plant machine shop , decades before Eliyahu M.
What about the second question, is TOC the same as Kanban? The answer is no, but this answer is worth elaborating a bit. Synergies How did my colleague made an association between the two concepts? If they are not the same, why do they feel similar? What are the synergies between Kanban and TOC?
Shared roots Both concepts have their origins in manufacturing. Goldratt used a manufacturing plant to introduce the TOC concept in his book; Kanban was originally created to improve the manufacturing processes at Toyota. Improving throughput TOC is a concept that can be applied to a process or system to improve the throughput by eradicating limiting factors.

Because JIT and TOC share many elements with MRP and because MRP is very flexible, it is not difficult to make MRP behave like JIT or TOC.
It achieves this by a five steps simple algorithm: The adaptation of Kanban to software talks about improving the flow of value to customers, where value is typically expressed as Features of a product or a service being built or enhanced.
From this point of view, both Kanban and TOC have the same goal not punt intended here. Hunting for bottlenecks While both concepts share an ultimate goal of improving the throughput of a process, they are going about achieving it in a slightly different way.
TOC focuses on a system constraint, the most important limiting factor s that stands in the way of achieving the goal, and then improving the constraint until it is no longer a constraint in the book this was the most heavily loaded machine.Materials Requirements Planning versus Just in Time In the preceding chapters, a great deal of space was dedicated to the importance of materials requirements planning (MRP) to contemporary SCM.
