Abstract:   The “Test Like You Fly” (TLYF) Process tutorial is based on an approach that is broader than “test.” It is specifically defined here as a prelaunch/pre-operational systems engineering process that translates mission operations concepts into operationally realistic tests to detect latent mission critical flaws. The approach is unlike typical requirements driven verification tests.  

The process incorporates a “pre-mortem” fault analysis to better understand how the mission could fail and use that insight to craft tests to flush out those flaws. The process also includes fault-informed risk management to account for unexonerated flaw paths to mission failure.

As a result of this tutorial, students will be able to: Understand the value of applying the TLYF Process in the context of systems engineering and mission assurance; Describe each of the TLYF Process implementation steps, their interactions and expected results/products; Gain awareness of the distinctions between the tests formed from the TLYF Process and other test techniques/methods; Apply the TLYF Process to complex mission driven system development projects; and Use the process to influence programmatic decisions.

The first session of this two-part introduction to the TLYF Process provides an overview that shows a methodical way to arrive at operationally realistic and relevant tests and to understand the risks when those tests cannot be done or are done in a manner that differs from actual usage. The second session will be an interactive example of using this process for a notional space (satellite, booster, ground control) system.

BIO:  Julie White has been with The Aerospace Corporation for over 45 years.  She is currently a senior project leader in the Systems Integration & Test Office (SITO) of the Systems Engineering Division. She has extensive experience with requirements analysis, integration, test and operations.   She has helped architect “like you fly” “days in the life” tests for four USAF Space Test Program one-of-a-kind R&D missions.  She spent time analyzing trends and the engineering implications of serious and fatal on-orbit satellite anomalies that occurred over a 30 year period worldwide. The large number of serious anomalies whose escapes could have been prevented by consistent implementation of TLYF techniques was the motivation for creating a TLYF assessment and execution process.

She was a contributor to the 1st edition of the Space Vehicle Test and Evaluation Handbook (The Aerospace Corporation, 2006) and senior editor and contributor for the 2nd edition of this book (The Aerospace Corporation, 2011).  She has written and presented several international papers on the TLYF Process, as well as others on risk management, mission development, satellite End-of-Life trends, and other on-orbit mission results.  She holds a Bachelor’s degree in Physics and Astronomy from the University of Maryland, College Park, MD, and a Master’s degree in Astronomy from the University of Massachusetts, Amherst.
