Management Attention
The real constraint: management attention.
The 3 fundamental mechanisms wasting anddistorting management attention:
q The fear of Complexity -> driving to dissect the systemto sub-systems and bringing damaging local optima.
q The fear of Unknown-> driving to finer and finer detailresolution trying to impose certainty on uncertainty.
q The fear of tug of war -> struggling with unacceptablecompromises.

Some insights Some fast moving items are not available in the
store for about 15-20 weeks a year (on average)
Much of the products in the universe do not get the
chance to develop significant sales level (90% ofSKUs contributes 35% sales).
There is a long and fat tail by nature (20% ofstock is over a year old).

1. Replenishment of Best Sellers (Head)- Identify best sellers and replenish from stock.- Inventory should be held based on consumption within the replenishmenttime factored for variability dont try to be accurate with a forecast!- Frequent replenishment of each SKU remove any artificial batch- Dynamic buffer management remove dependency on forecast

2. Daily Indenting Process (Belly)
- Use live real data to shift the mix within categories to faster movers.
- Make it fast and frequent.
-The process is performed at the store every morning consideringyesterdays sales as an input:
- For each sold variant the best alternative is presented as thedefault indent
- The best alternative is the same variant - if sold fast, otherwise itis the best selling variant on the same category and price band
- The store can change the default by selecting an alternative item
from a closed list of alternates which are national best sellingvariants

3. Rotation of Aged Inventory (Tail)Channel the aged inventory to stores that have demand forthese items. Aged inventory is recalled and is redistributed tothe stores that ordered it. The stores that have to give back
aged items, indent fresh items for replacement
