Total Life Cycle Management Key Considerations: A Logisticians Perspective

TLCM is an end-to-end, integrated and iterativesystem engineeringprocess
Logisticians need to be involved continuously inall phasesof the total life cycle process
Sound system engineering practices in the TLCM process willenhance the supply chain managementfunctionality
Metrics Matter – if you can’t measure performance outcomes customer satisfaction becomes a guessing gameTotal Life Cycle System Management (TLCM)
Key Consideration #1
What is it?
What it does?
How to do it?
Transformsrequirements into a system architecture through an iterative and recursive design & development process
Integrates performance, reliability, maintainability, supportability, survivability, and other design goals into the system
Disciplined approachused to assure process compatibility & product (hardware & software) interoperability
Ensurescompliance with design throughout life
Integrate all life-cycle requirements
Balance cost, schedule, performance & risk
Technical discipline throughoutlife cycle
Generates and tracks technical information needed for decision making
Ensures essential technical things get done
Verifies technical solutions satisfy requirementsWhy use the SE Process?
Balances cost, schedule, performance, & risk
Integrates all life-cycle requirements (cradle to grave)
Provides technical discipline throughout the life cycle
Ensures essential technical activities get done
Generates, tracks, and archives technical data needed for decision making

Key Consideration #2
Interoperability is the ability of independent systems to exchange meaningful information and initiate actions from each other, in order to operate together to mutual benefit. In particular, it envisages the ability for loosely-coupled independent systems to be able to collaborate and communicate.
Ref. ISO/IEC 21000-6 Dictionary
Standardizationis essential for interoperability.
Commonality is one outcome of standardization.
Standardization and commonality can make logistics support more effective, less costly, easier, and faster.
Standardization and commonality can improve readiness, availability, and reliability and supportabilityInteroperability, Standardization, & Commonality
Compatibility means systems or units do not interfere with each other’s functioning.
Itdoes notimply the ability to exchange services.Interoperability & Compatibility
Interoperable systems are by necessity compatible, but the converse is not necessarily true.
An integrated family of systems must be interoperable, but interoperable systems need not be integrated.
Integration ContinuumInteroperability, Compatibility, & Integration
New systems will need to be interoperable
Modifications to existing systems will need to enable interoperability.
New acquisitions and contracts will need to include interoperability and address standardization and parts management.
Standards are needed to ensure interoperability between the newest technical systems and legacy systems.Addressing 21st Century Interoperability Requirements

Key Consideration #4
A supply chain consists of all parties involved, directly or indirectly, in fulfilling a customer request. The supply chain not only includes the manufacturer and suppliers, but also transporters, warehouses, retailers, and customers themselves. Within each organization, such as the manufacturer, the supply chain includes all functions involved in receiving and fulfilling a customer request. These functions include, but are not limited to, new product development, marketing operations, distribution, finance, and customer service.

A basic supply chain consists of a company, and immediate supplier, and an immediate customer directly linked by one or more of the upstream and downstream flows of products, services, finances, and information…An ultimate supply chain includes all the companies involved in all upstream and downstream flows of products, services, finances, and information from the initial supplier to the ultimate customer
Supply chain management is the integration of business processes—from the end user through the original suppliers—that provide products, services, and information that add value for the customer.

Involves Coordinated Management of Logistics Processes
Metrics are simple.
If metrics require a lot of explanation and definition, then collecting data, and translating that data in to actions becomes difficult.
Easy-to-understand metrics have a strong impact on the process and the people who use it.
How do you know what you know?
A metric is a standard measure to assess
performance in a particular area.
A performance measure, is an
indicator which conveys information on
the level of success or achievement
of a program or activity.
Specific and targeted to the area being measured.
Accurate and complete data is collected and correlated against a standard.
Allows corrective actions to be taken or maintained.
Don’t measure things that are not important!
Data is available when it is needed.
metrics is not easy!!
Don’t measure total supply chain performance only wholesale performance. Others simply measure the implementation of an initiative without any link to the performance metrics that should indicate the resulting supply chain improvement.
Not linked or correlated to one another so managers can consider important supply chain relationships. For example, reduced inventory may not be beneficial if readiness rates are declining.Supply Chain Metrics

Today - OIF
More is better
Large amounts of material measured in days of supply
Use massive inventory to overcome uncertainty in demand and supply
Mass inventories slow down operational flexibility and
Inventory is dynamically positioned throughout
Uses transportation flexibility and modern IT to handle demand uncertainty
Supports distributed, uncertain operations
On-time is better
Inventory is reduced to a minimum and kept moving
Use demand prediction and static optimization to purge uncertainty
