Technical Interchange Review

The government-wide, web-based system contracting officers use to record formal, periodic assessments of a contractor's performance (cost control, schedule, quality, and management) on individual contracts. CPARS reports become the official past performance record that other agencies typically pull when evaluating that contractor's proposals on future source selections.

Technical evaluation of a design, system, or proposed approach against stated requirements, using calculations, modeling, simulation, or test data to confirm feasibility, performance, and risk. In a proposal, engineering analysis is the evidence that substantiates technical claims rather than simply asserting them.

A source-selection evaluation factor that examines how well an offeror executed relevant prior contracts (quality, schedule, cost control, and management effectiveness), typically documented through CPARS records, references, and questionnaires. In many best-value competitions it carries weight comparable to technical approach or price.

A pricing analysis that estimates what price is needed to win a specific competitive procurement (based on competitor cost structures, historical awards, and the customer's budget), then works backward into a bid strategy and cost model that hits that price while staying profitable. PTW produces a pricing strategy, not a likelihood of winning.

A pursuit team's estimated percentage likelihood of winning a specific competitive opportunity, based on factors like incumbency, customer relationships, technical solution strength, teaming, and competitive positioning. PWin is reassessed at bid/no-bid gates to guide resourcing decisions, and is distinct from price-to-win, which sets a bid price rather than measuring how likely that bid is to win.
