KPI (Key Performance Indicators) report shows important indicators of the current project performance. Streamline calculates a variety of indicators. Most of them evaluate the inventory planning process.

The table below is a brief description of the indicators.

Below we give a more detailed description of these KPIs.

There is a set of KPIs that depends on the item value. Item value is a characteristic that is taken as Inventory value/unit or Purchase price/unit data type. If both data types are given, the former is taken as the item value.

Item value-dependent indicators are the following:

• Inventory value
• Expected overstock value
• Non-moving inventory value
• Gross margin
• Annual gross profit

Below we explain how they are calculated.

The Inventory value indicator shows the value of the item in stock. If it is not imported directly using the Aggregated spreadsheet connection, it is calculated as:

The Expected overstock value indicator indicates the expected overstock value for an item. It is calculated as:

The Non-moving inventory value indicator is calculated for those items that will not be sold during the forecast horizon according to the forecast. Streamline doesn't compute this KPI for items that are forecasted using an intermittent demand model. The formula for this indicator is:

The Gross margin indicator is the monthly gross profit margin. Its calculation is based on the compound interest and the formula looks like:

where:

• avgSalesPrice – the average selling price for the current month;

• lead time – is the Lead time or DC lead time depenting on the echelon the item resides at;

• interest rate – the annual interest rate that is taken from the Settings

This indicator is an aggregation of transactions' profit over the last 12 complete months. It is calculated in two ways depending on the available data:

1. It is the sum of the Transaction profit imported from the data source.
2. It is calculated using the formula:

where:

• N – the number of data aggregation periods making up 12 months;

• avg sales price_t – the average sales price over the t-th period. It can be calculated if the Sales price/unit data type was imported;

• sales_t – the item quantity sold in the t-th period.

Streamline uses the first method primarily.

The Expected stockout value indicator is the expected inventory deficiency value in the base currency. It is calculated as:

where avg sales price is the average sales price in the current period. If we don't have sales in the current period, data of the previous period is used.

Inventory turnover tells how many times an item was purchased and then sold out over a particular period of time. Its formula looks like:

where:

• N – the number of days in the period;

• Sales_i – the item quantity sold on i-th day;

• K – the number of days in the period without stockout;

• On hand_i – stock on hand at the end of i-th day. It is determined based on On hand change or On hand (as remaining after a transaction) imported from the data source.

If sales history can't cover the period, it is brought to it proportionally using the formula:

where:

• N – the number of days in the period;
• K – the sales history length in days;
• Sales_i – the item quantity sold on i-th day.

The Turns/year column of this report shows the turnover over the last 12 months.

This indicator shows an item gross margin accumulated over the last 12 months and calculated as:

This indicator is usually used to rank products and find the most profitable items.

Let’s explain how this indicator is calculated. Consider the product sales history depicted in the figure below.

To calculate annual revenue in this case, Streamline always skips zero demand before the sales have started. So only the sales of the last 8 months are taken into account. The formula looks like:

If we have sales history shown in the figure below, then sales of all the months are taken into account:

So, as you see, this indicator depends on the sales history of the last 12 months, and thus, may significantly change from month to month.

If the forecast horizon is one year, the next year's revenue is the summed revenue of the next 12 months. Otherwise, it is calculated proportionally using the available data. For example, if data aggregation period is one month, this indicator is calculated as:

where:

• n is the number of months to forecast ahead;
• Revenue_n is summed revenue over the future n months.

The annual sales value sums up the quantity sold over the past 12 months. It can be found in the Actual sales line in the Demand Tab.

The next year sales value indicates a possible amount to be sold. It’s a sum up of the forecast in quantities for the next 12 months.

This indicator shows the purchase amount for each planning item. It is calculated based on the current purchase recommendations. This column allows you to view the total purchase amount by each supplier if you group this report by the Supplier using the Aggregate by drop-down.
