Carrier Scan Latency

Introduction

Designed for Carrier and Customer Service Managers, the Carrier Scan Latency report provides an overall view of how fresh your data is. It does this by showing, for each carrier, the time lag between carrier scans and the processing of the scans in Metapack Delivery Manager.

The report can be used to:

  1. Detect those carriers and carrier services for which there is unacceptable scan latency.

  2. In conjunction with the Carrier Tracking Data Quality report, gauge the likely accuracy of your exception and other reporting.

Note

The delay reported on is the end-to-end latency, which includes both the carrier's and Metapack's processing times.

Reports by Carrier

The report looks at the scan dates during the last 32 days and displays the following headline information, breaking it down by carrier in a graph to the right and a table underneath, e.g.

The graph to the right illustrates the carrier breakdown and highlights any outliers. As a general rule, the more compressed the bands are at the very bottom of the graph, the more consistent the carriers are in terms of latency.

In terms of the table, the figures are liable to be skewed by the outliers shown in the graph. The definitions (taking account of these outliers) are as follows:

  • The 75% below figure, which is possibly the most helpful, tells you that 75% of the carrier's scans are being processed in Metapack Delivery Manager within the timeframe shown.

  • The 25% below figure tells you that 25% of the carrier's scans are being processed in Metapack Delivery Manager within the timeframe shown.

  • The Mean Average is the average time taken for a carrier scan to be processed in Metapack Delivery Manager.

  • The Median Average is the time taken for 50% of the carrier scans to be processed in Metapack Delivery Manager.

  • The Minimum (latency) is the shortest time possible from the carrier scanning a parcel to the scan being processed in Metapack Delivery Manager.

  • The Maximum (latency) is the longest time possible from the carrier scanning a parcel to the scan being processed in Metapack Delivery Manager.

Report graph showing Modal Average

The first graph below the Reports by Carrier shows how long the scans for all carriers took to be processed in Metapack Delivery Manager.

The highest bar in the graph represents a Modal Average (i.e. the most frequent occurrence - e.g. most scans are processed in Metapack Delivery Manager within the 1-2 hour slot).

Report graph showing Spikes by Carrier

The second graph shows any particular days on which there were spikes in latency by the different carriers, so that you can investigate whether there were any issues on the days in question.

Filters

In the filters at the top of the report, you can set the timeframe for which parcels are to be shown. The default is the last 32 Days of manifested parcels (to give a full month of data):

Note

Both the Origin Country and Destination Country filters are defaulted to the UK to focus on domestic traffic and so avoid any skewing of latency when changing timezones.

The default Latency in Minutes of >=0 ensures the exclusion of negative latency (e.g. where some carriers mark delivery at a time in the future such as end of day (23:59)).

You can also restrict the data to a specific carrier, 'carrier service', 'service group', warehouse and/or market.
