Canalys updates its client PC shipment forecast estimates in the seventh week of every quarter. While the data is designed to help its clients by providing appropriate metrics that can serve as a feed to their internal planning processes, Canalys also supplements this data with key assumptions that can affect, both positively and negatively, demand for and supply of PC shipments worldwide.
In the forecast released on 20 February 2020, Canalys compiled all the information available to it from multiple sources, including but not limited to equipment vendors, ODMs, OEMs, supply chain companies, channel partners, retailers and ISVs. This forecast is especially important as it analyzes the effects of the COVID-19 outbreak that has affected multiple countries around the world, albeit with a higher level of severity in China and Asia generally.
