Supportability Analysis, otherwise known as Product Support Analysis (PSA) and Logistics Support Analysis (LSA), is a structured process for optimally defining the requirements for and reducing the cost of providing support for an asset.
Total cost of ownership of an asset is more than a purchase price. It includes the cost to maintain the asset through its projected life cycle. The purpose of PSA is to define, analyze, and quantify the asset's support requirements. Done effectively, PSA can not only reduce the asset's total cost of ownership, but influence the design of the asset to improve supportability. Defining and assessing necessary support resources through the life of an asset provides the information needed to reduce cost drivers while improving the efficiency of providing support.
The results of the analysis – the output of the PSA – is the Logistics Product Data (LPD). This is a structured repository cataloguing the data used in or resulting from the PSA. This data, also known as the Logistics Support Analysis Record (LSAR), can be used and reused/repurposed in many ways, such as creating a benchmark for a future similar program or design change, or for creating ancillary integrated logistics support documents, such as technical documentation.Learn More
