System Engineering Key Consideration #1 What is it? What it does? How to do it?
What Is The Systems Engineering Process? 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
Develops atotal systemdesign solution 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 requirements Why use the SE Process?
Who uses the SE Process? • Government (DoD) • Defense Industry • You • Others
SE Process Supportability Inputs • Available ? • Reliable ? • Maintainable ? • Deployable ? • Sustainable ? • Affordable (Support Cost) ?
Design Solution • Transforms the architecture (functional to physical) • Each part/task must meet at least one functional architecture requirement • Any part/task can meet more than one requirement • Define alternative system concepts, configuration items & system elements • Select preferred product and process solutions • Define/refine physical interfaces (internal/external)
Logistician’s Role in Design Solution Includes: • Identify & design support tasks • Determine support resources • Develop support products & processes • Maintenance, Supply, and Training Plans • Technical Publications, etc • Define & implement PBL support environment
Develops a total system design solution 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 Verifies technical solutions satisfy need What the SE Process Does

Interoperability 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
Interoperability • Joint Pub 1-02 • (DoD–NATO) The ability of systems (units, or forces) to provide services to and accept services from other systems, units, or forces and to use the services so exchanged to enable them to operate effectively together. • (DoD only) The condition achieved among communications–electronics equipment when information services can be exchanged directly and satisfactorily between them and/or their users. The degree of interoperability should be defined when referring to specific cases.
Interoperability is essential in the modern domestic/military environment. 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 supportability Interoperability, Standardization, & Commonality
Compatibility is something less than interoperability. 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.
Although interoperable systems can function independently, an integrated system loses significant functionality if the flow of services is interrupted. Interoperability and Independence An integrated family of systems must be interoperable, but interoperable systems need not be integrated.
Interoperability lies in the middle of an “integration continuum,” somewhere between compatibility and full integration. Interoperable Fully Integrated Compatible Integration Continuum Interoperability, Compatibility, & Integration
Mitigation opportunities 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

Supply Chain Management 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.

Supply Chain Management Metrics 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.
Why Develop Metrics at All? • Improve your performance • Provide objective quality evidence • Measure your processes How do you know what you know?
Metrics 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.
SMART Metrics SSpecific Specific and targeted to the area being measured. MMeasurable Accurate and complete data is collected and correlated against a standard. AActionable Allows corrective actions to be taken or maintained. RRelevant Don’t measure things that are not important! TTimely Data is available when it is needed.
Developing effective metrics is not easy!! SMART Metrics • Top 5 Common traps that should be avoided in developing effective metrics: • Developing metrics for which accurate or complete data can not be collected • Developing metrics that measure the right things, but cause people or the organization to act in a way contrary to the best interest of the organization (“make numbers”) • Developing so many metrics that they create excessive overhead or red tape • Developing metrics that are complex and difficult to explain • Developing metrics without defining applicable ground rules and assumptions
Although many current metrics provide useful information, they don’t provide senior managers with a sense of how well the supply chain is performing. 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
Categories of SE Metrics • Metric Categories include: • Progress Metrics: • Cost/Schedule Variances • Earned Value • Status of Risk Events • Product Metrics: • Operational Availability • Mean Time Between Failure • Weight, Speed, Payload, Range • Unit cost • Process Metrics • Number of Design Changes • Cycle Time • Defect Rates • Length of Team Meetings
