Seminar 6 Production Planning Process
Today’s opening discussion was interesting.
We were given a list of open items and their due dates, and asked which of them
were to be netted at the end of month by the company. I totally had no idea due
to the lack of information. But some of my classmates suggested some convincing
solutions based on past experiences from other companies, so I also ended with
guessing. However, this was actually wrong, and what we were guessing was mere
assumptions. Of course, we could not make decisions only based on assumptions. I
was correct in the beginning, but I failed to insist on my own opinion as
usual. Right! I have to be more confident!
Review on P2P
Every time the review activities given by
James can surprise me, because it is always about some aspects that I haven’t
thought about. Again, this time it is about the procurement of non-inventory
items. Do we need to go through the same process as the inventory items, just
like what we’ve done when doing the P2P lab? To be frank, I really haven’t
considered this situation. This is probably due to my lack of working
experience, because in the CCAs that I joined there was always
only one treasurer. No matter what kind of expenses incurred, from the essential
props to the printing and transportation fees, we just go to the same person to
claim money. This is plausible for such small and one-time activities, but is
disastrous for companies. According to the Kraljic’s
Portfolio Matrix, inventory items are strategic items, while non-inventory items are non-critical items. And the store
room for non-inventory items should also be separated from warehouse for
inventories. So companies should not spend much time sourcing and dealing with
the non-inventory suppliers. A suggestion is that these items should be
purchased in bulk and at a scheduled time, so the requesting departments know
when and what to buy. Some group suggested that purchasing department could
help ask for a good price, and other departments could just place order after
that. This solution sounds tedious, but it could be done by an SAP integrated
system called SRM (Supplier Relationship Management). SAP is a real helper!
Production planning
Again the student-led session introduced
the new topic for today – product planning. Everything here starts from
forecasting, which is based on both past year sales and current year market
conditions, counting any variables, such as advertising campaigns and seasonal
changes etc. Series of calculations are also involved in the process, from the
inventories to materials, and from quantities, lot sizes to delay time and so
on… Even the class activities were all about calculations. This is essential for the company,
since all the following operations, such as material purchasing and production
executions, will be based on the plans.

Nonetheless, the plan is from forecasting, which is not likely to be always accurate, so the forecasts need to be revised frequently and regularly. This is why the financial experts are invited every day on TV to analyse and predict the stock market, although the analysis is possibly more or less the same. But unlike the subtle impact of stock predictions, a failure on production planning can kill a firm. Gratefully, we have MRP (Material Requirement Planning) system, by which the lowest material and inventory level is kept while sufficient available amounts are also guaranteed. Since the presenting group made a small mistake, and James mentioned about MRP II (Manufacturing Resource Planning), I went to Google and found that MRPII is an extension of MRP. Besides all the standard process of production planning (MPS, BOM etc.), MRPII includes capacity planning, cost control and other modules as well, so it is more complete.

How does ERP help in this case? Needless to
say the automated mass calculations, ERP helps connect different departments,
so the information for the process can be synchronised. This is not a new
point, but it’s true and extremely helpful for efficiency enhancement.
In addition, various production strategies
were discussed. First, make-to-stock is the normal strategy for common
products, just to produce based on sales anticipation. Make-to-order is usually
applied by companies that provide very large and high-cost customizable
products, such as home design and stages. James added another strategy, which
is ensemble-to-order: the products are not fully customizable, but customers
could choose from different pre-designed elements. For example, some automobile
and computer companies are applying this strategy. As for just-in-time, it
is more like a philosophy that can be applied in many places besides
make-to-order strategy. For instance, it can be used to ensure that the products
are received in time by the customer when using other production strategies.

The last point was about lot size. Although
EOQ (Economic Order Quantity) is used in the presentation to minimise inventory
holding cost and ordering cost, lot size is usually decided by the supplier. It
is like the situation where you want to buy a bottle of Yakult, but Cheers only
sells a row of it and you simply can’t tear the package and only buy one of
them.
Ahhh~ what a harvest day! I can go to sleep
contentedly :) !
