Logistics support analysis

Logistics Support Analysis (LSA) is a structured approach to increase efficiency of maintenance and reduces the cost of providing support by preplanning all aspects of Integrated Logistics Support. A successful LSA will define those support requirements that are ideal for the system design.

History
Logistics Support Analysis was codified into a military standard in 1973 with the publication of Military Standard 1388-1. Logistic Support Analysis (LSA)guidelines and requirements were established by Department of Defense (DOD) Instruction 5000.2, Major System Acquisition Procedures, and DOD Directive 5000.39, Acquisition and Management of Integrated Logistic Support for Systems and Equipment, to create a single, uniform approach by the Military Services to improve supportability of military weapon systems through a disciplined approach to defining the required operational support other Integrated Logistic Support (ILS) objectives during the acquisition development phase. 1388-1A was updated in 1983 and 1991 before being downgraded from a standard to a best practice on 26 November 1996. 1388-2A was updated in 1991 and 1993, and was also cancelled as a standard in 1996. The definitions for the database records of LSA were established by the Logistics Support Analysis Record, MIL-STD-1388-2A, on 20 JULY 84.

In 1986, the US Army began to transform the paper-intensive LSAR into a desktop application known as “Computer Aided Logistics Support” (CALS). The Navy began a similar effort in 1987. In 1991, the programs were combined and expanded to all services under the name Joint CALS (JCALS). JCALS was approved for use in August 1998.

Structure
As originally envisioned, the data was structured as a LSA Record (LSAR), as defined by MIL-STD-1388-2A (records) and MIL-STD-1388-2A (outputs)

tasks: LSAR output was structured as:
 * 15 Data records
 * 115 Date cards
 * 547 Data elements
 * 80 STD report formats
 * 104 Relational tables
 * 518 Data elements
 * 48 STD report formats
