Chapter 2: 2.1 Introduction 2.2 Recent Changes 2.3 Acquisition Life Cycle 2.4 SE in Acquisition 2.5 Summary Points S2-A Technology Readiness Levels S2-B Evolutionary Acquisition Considerations

Notes: The current SEF Guide describes the OLD DODI

5000.2-R Acquisition Process We just discussed the NEW version (DODI 5000.2) Some Major Differences:

Concept & Technology Development are separated by MS-A

Name of the final Phase Changed Some new Milestones MNSs and ORDs are replaced by ICDs and CDDs Others

USE THE NEW ACQUISITION WALL CHART As such, although many of the specifics of Chapter 2

are dated, the general approach described for iterative application of the SEP process to the DoD Acquisition Phases is still valid.

Chapter 2 Conclusions are still valid.

2.5 Summary Points The development, acquisition, and operation of military systems is governed by a

multitude of public laws, formal DoD directives, instructions and manuals, numerous Service and Component regulations, and many inter-service and international agreements.

The system acquisition life cycle process is a model used to guide the program manager through the process of maturing technology based systems and readying them for production and deployment to military users.

The acquisition process model is intended to be flexible and to accommodate systems and technologies of varying maturities:

Systems dependent on immature technologies will take longer to develop and produce, Systems that employ mature technologies can proceed through the process relatively quickly.

The system engineering effort is integrated into the systems acquisition process such that the activities associated with systems engineering (development of documentation, technical reviews, configuration management, etc.) support and strengthen the acquisition process.

The challenge for the engineering manager is to ensure that engineering activities are conducted at appropriate points in the process to ensure that the system has, in fact, achieved the levels of maturity expected prior to progressing into succeeding phases.

S2-A Technology Readiness Levels

New DOD 5000.2 Process requires a Technology Readiness Assessment (TRA) prior to Milestone B (for Major Acquisitions)

Critical Technologies need to be identified and characterized by Technology Readiness Level (TRL)

Chart to right provides definition for each level.

For Milestone B, most (all) critical technologies should be at TRL 5/6 or higher

S2-B Evolutionary Acquisition Considerations [1]

Evolutionary Acquisition is Characterized by:

Evolving Architectures Block Development &

Incremental Delivery (each block provides additional or upgraded capability)

Phased, concurrent development of Blocks/Increments

Planning Considerations: Clear description of core system and subsystems/ components

most likely to evolve Process for obtaining, evaluating and integrating operational

feedback, technology advancements, & emerging commercial Products

Planning for evolutionary block upgrade evaluation, requirements validation and program initiation

Description of the management approach for evolutionary upgrades with in block and the constraints and controls associated with incremental delivery of capability

Risk Analysis of the developmental approach, both technical and managerial

9

S2-B Evolutionary Acquisition Considerations [2]

SE Planning Emphasis: Openness and Modularity

of the design of the core system architecture (to facilitate upgrades)

Structure of Baseline Documentation (upgrade flexibility)

Impact of Evolutionary Acquisition on baseline development and document control

Structure of technical reviews to best support acquisition decision points

Risk Management monitoring and controlling of the programmatic and technical complexity associated with EA.
