Project Support Solution Transition Plans

Introduction – PSSS-TAA

At designated points in the life of any project it will be necessary to transition the product support solution knowledge from the OEM to the User. That is, from the acquisition phase to the sustainment phase. The product support knowledge is usually multi-disciplined and intensive and can be either qualitative or quantitative. PSSS-TAA is a tailorable method to prepare a Transition Activity Analysis to examine and explain the transition of a proposed product support system solution of a project from the acquisition phase to the sustainment phase. The transition consolidates and analyses information provided in a range of project definition documents. These documents include the OSC (Operational Support Concept), SOW (Statement of Work), DIDs such as DID-ILS-DEF-SSSPEC Support System Specification and DID-ILS-DES-SSDECS Support System Description, Integrated Support Plan (ISP), Requirements Analysis Guide ((ENG)12-3-002), and other plans as specified.

The Support System Constituent Capability (SSCC) as described in DEFLOGMAN is the framework for this analysis. There are 33 elements in the SSCC that will need to be populated from the analytics. DID TDID-ILS-DEF-PSSS-V1.2 Proposed Support System Solution (PSSS), or equivalent, will be used to detail the Proposed Support System Solution.

A SSCC life cycle analysis (LCA) is to be carried out as part of the transition plan. The life cycle analysis is to follow DID TDID-FIN-LCC-TLCMM Tender Life Cycle Cost Model or equivalent, to the maximum extent possible. The rigor of a fully populated SSCC depends upon analysts with a wide range of interdisciplinary skills in the product support domain. This workshop provides that knowledge rigour.


To develop a project Transition Activity Analysis (TAA) method. It is a living document and captures transition information over the life of the project from the beginning to the fielded system.

Summary of Activities

Activity topics include statistics, cost calculations, descriptions and explanations, and general calculations. This method adapts the selection of material to suit the deliverable requirements and form the body of knowledge for analysis. The main analysis is based on the SSCC context. A wider Integrated Logistics Support (ILS) should be addressed to identify those items In need of analysis.

We work with you to develop these key plans to achieve operations outcomes.
