The bullwhip effect in supply chains has been around for some time now. The term “bullwhip effect” originated at Procter & Gamble, and is defined as: demand amplification across echelons within a supply chain. This describes the effect that end customer demand may be very static (as for “Pampers” by Procter & Gamble), but the demand experienced by the manufacturer or supplier shows amplified demand variations. (Fransoo and Wouters (2000))

The article reviewed here takes a look at typical biases in supply chain demand planning and how to avoid it. This work could prove very valuable for many companies who rely on manually adjusted forecasts.
Usually the forecasting process uses two steps:
1) statistical forecast by the forecasting system
2) manual adjustment to include additional effects (eg. additional analysis of demand pattern not included in step 1)

My professor gave me the hint to look for a systematic literature review approach which has been used at Cranfield University in the UK. Actually I found the description of a methodology to be used for a “systematic review”, that can be quite useful.

The CSCMP’s Supply Chain Quarterly just published their first issue for 2010. One of the articles deals with the rising interest in reducing working capital using the example of Kraft Foods.
As well as other companies Kraft already had prior cash flow initiatives, where they analyzed their WC positions: payables, receivables, inventory, and capital expenditures.
