LSA Task Division
(Logistics Support Analysis / Procedures)
LSA can be used in a number of design applications such as:
Large-scale acquisition programs for major systems
Major modification programs
Research and development programs.
No matter how large or small the application, using appropriate LSA
Makes supportability requirements an integral part of product
Defines the best, interactive support requirements for a particular
Defines the support needed for product operation
Provides data that analysts can use to keep the
design on track.
As each design program is unique, all LSA tasks are not needed for every
program. Although primarily a customer responsibility, the customer and the
contractor LSA representatives select and tailor the individual tasks needed
to satisfy the specific characteristics and support requirements of a
particular design program.
LSA Task Division
LSA tasks fall into three general task categories. The three general tasks
are expanded into five major task categories. The five major tasks are
expanded into 15 specific LSA tasks. These general, major, and specific LSA
tasks are discussed in the paragraphs that follow.
General LSA Tasks
LSA tasks fall into three general interactive categories common to any
Management of the LSA program
Analysis of logistic support requirements and
incorporation of those requirements into the design
Testing and refining the identified logistic
support, as needed.
These tasks are ongoing throughout the product design and development
Management of an LSA program must begin as early as possible in the design
Development of an LSA program must begin during the pre-concept phase of a
product and must continue to evolve throughout the lifetime of the design and
Analysis and Incorporation
Most analysis tasks begin as early as the pre-concept phase of the design
process. These tasks are repeated throughout design development, examining
more data in greater detail with each iteration. For example, a use study
identifies and documents the support factors for a proposed product and is the
prerequisite for all other analysis tasks.
Incorporation tasks inject the analysis results back into the design
process. The resulting changes are then analyzed in the next iteration.
Development of alternative support systems from use study data is an example
of an incorporation task. The product design is then altered, as needed, to
incorporate the alternative support requirements.
Working down from the top design level, design and support tradeoffs are
made to fine-tune the logistic support needed for successively lower design
levels, such as:
Identifying repair and discard tasks
Recommending design changes to achieve improvements
Allocating tasks to specific maintenance
Analysis and incorporation tasks influence design and operational concepts
Estimating overall logistic requirements of all alternative
Relating overall design, operation, and support characteristics to product
Defining design subsystems, such as hardware and software
Identifying, evaluating, and performing specific tradeoff
Identifying specific support resource
Testing and Refining
Testing, evaluating, and correcting deficiencies in the product design and
the selected support system must begin early and continue throughout the
Test results must be validated within stated standards and should be
replicative. After validation, these results are used to refine and correct
the design and/or the support system.
All three general areas of LSA, thus, work hand-in-hand to develop a
product design and support mechanism to create a quality
The three general tasks are expanded into five major LSA tasks as
Program Planning and Control
Program Planning and Control is divided into three specific tasks that
establish the mechanisms for good LSA program management:
These tasks can be used for almost any kind of acquisition pro-gram -
hardware development, off-the-shelf hardware, software development, and
modification of existing equipment.
Equipment and Support Systems Definition
Equipment and Support Systems Definition has five specific tasks for
identifying support parameters for a new or modified product:
Conduct Use Study
Standardize Hardware, Software, and System Support
Employ Comparative Analysis
Seize Technological Opportunities
Incorporate Supportability and Related Design
These tasks are designed to determine the actual operational environment,
what the product is required to do, and the support needed to continue
functioning in that environment.
Preparing and Evaluating Alternatives
Preparing and Evaluating Alternatives is divided into three specific tasks
for generating support system alternatives and performing tradeoffs to
determine the best support system:
Identify Functional Requirements
Determine Support System Alternatives
Evaluate Alternatives and Tradeoff
These tasks further detail the proposed system functions and alternative
support for those functions. They identify possible risks of the alternative
support methods and provide a vehicle for improving existing system support.
Determining Logistic Support Resource Requirements
Determining Logistic Support Resource Requirements is broken into three
specific tasks that analyze the specific operation and maintenance tasks and
then identify the support resources required to carry out those tasks:
These tasks are applied only after the design is fairly well developed to
see if the existing support system is adequate. The specific design features
are examined in detail to determine their specific support requirements: e.g.,
needed personnel, skill levels, needed facilities, repair requirements.
Supportability Assessment has one specific task for assessing the
effectiveness of the logistic support developed for the designated system:
Conduct Supportability Test, Evaluation, and Verification.
Specific LSA Tasks
As described in the Major LSA Tasks paragraph, the five major LSA tasks are
divided into 15 detailed, specific LSA tasks. All these tasks are shown in the
associated graph and are discussed in detail in the Applications Section of

LSA Task Tailoring
The specific LSA tasks have been developed to cover many different
procurement situations. To be effective for a particular program, the LSA
tasks must be selected, or tailored to fit the circumstances.
Tailoring LSA tasks to the needs of a particular program is
imperative. Not all tasks apply to all programs.
Performing LSA tasks not needed to meet product design and development
objectives wastes resources.
A product design program specifying all LSA tasks is no more valid
than a program specifying none.
Tailor LSA tasks to a particular program by repeatedly applying the
How will the data provided by the task be used?
Is there freedom to change?
Is there time, money, or need to change?
Refer to MIL-STD-1388-1A for a more detailed tailoring method.
Many disciplines are involved in implementing LSA tasks. If left solely to
logisticians, an LSA program will fail. Designers, specialty engineers (e.g.,
Reliability and Maintainability), manufacturing personnel, and many others
must taken an active part.
Most important of all, however, is involvement of both contractor and
customer program management. LSA is a management tool; if it is not used,
product development will suffer. Also, program managers should use LSA to
impact product development positively to achieve the best
