Did company Y identify all of the factors relevant to the introduction of the system at the outset and, if not, what did they miss? On the basis of the conducted interviews of the different department heads of Company Y, the introduction of MRP II was rather unsuccessful. Among the problems was teamwork and team building. This factor is very common in company Y and important since this has to take place for the system to be effective, the team has to focus on common objectives between and within various departments of the organization itself, majority of the department heads are pointing to the production department which is practically the core of the company since company Y is into production of chemicals, the production department tends to do things on their own way resisting and disregarding the system and how it should work in the first place, this has gotten the company with stock accuracy as well as inventory imbalances making the system completely useless.
It includes all of the elements of MRP, it: Feedback MRP II includes feedback from the shop floor on how the work has progressed, to all levels of the schedule so that the next run can be updated on a regular basis. Resource Scheduling There is a scheduling capability within the heart of the system that concentrates on the resources, i.
The advantages of this development are that detailed plans can be put to the shop floor and can be reported on by operation, which offers much tighter control over the plant. Moreover loading by resource means that capacity is taken into account. The difficulty is that capacity is only considered after the MRP schedule has been prepared.
It may turn out that insufficient time was allowed within the MRP schedule for the individual operations to be completed. Batching Rules Batching rules can be incorporated, indeed they have to be if resource scheduling is to take place. Most software packages offer a variety of batching rules.
Therefore if a company is planning to make 10 of Product A followed by 20 of Product B, then the batches throughout the process will match this requirement. If both A and B require two of a certain sub assembly then that will be made in quantities of 20 of A and 40 of B.
It is the batching implicitly followed in basic MRP. The batch size is calculated by a formula that minimises the cost through balancing the set up cost against the cost of stock. A policy of making a weeks requirement in one batch is an example. Some of these are further designed to help the scheduling procedure.
The most important is Rough Cut Capacity Planning RCCPan initial attempt to match the order load to the capacity available, by calculating using a number of simplifying assumptions the load per resource.
Overloads are identified and orders can be moved to achieve a balance. This has been described as "knocking the mountains the overloads into the valleys periods of underload ". For example it may include an option for entering and invoicing sales orders Sales Order Processing.
Another common extension is into stock recording and a third into cost accounting. Data accuracy This last development means that the company must put great emphasis on data accuracy. Errors in recording in one part of the system will result in problems for all the users.

Based on the analysis of survey responses from MRPII users, the characteristics of the MRP II users are identified, the approaches and problems encountered in MRP II implementation. This paper assesses the reasons for the success or failure of manufacturing resource planning (MRPII) implementation projects.
