Definitions What is Systems Engineering the ensemble of coordinated anal yses simulations and processes which lead to a technical product which best meets the needs of an identified customer What does it mean to manage systems engineering Systems engineering management requires the allocation of resources in a manner that ensures success Resources include funds, schedule, personnel, tools, and environment Proper allocation requires that the manager continuously predicts the future needs of the program and technical hurdles and allocates the currently available resources such that these needs are met and these hurdles are cleared at the appropriate time Systems Engineering Management
Definitions • What is Systems Engineering? – the ensemble of coordinated analyses, simulations, and processes which lead to a technical product which best meets the needs of an identified customer. • What does it mean to manage systems engineering? – Systems engineering management requires the allocation of resources in a manner that ensures success. – Resources include funds, schedule, personnel, tools, and environment. – Proper allocation requires that the manager continuously predicts the future needs of the program and technical hurdles and allocates the currently available resources such that these needs are met and these hurdles are cleared at the appropriate time.

The restaurant analogy INGREDIENTS-available technologies funds schedule personnel, etc APPLIANCES-tools(e.g, software) for synthesizing, modeling, and analyzing a design KITCHEN -environment in which tools and communications are exercised (e.g., design room) cheF assistants- the systems engineering team RECIPE-the sequence of activities, tests, and refinements used to ensure the successful completion of the product MEAL-the product that arrives on time, on budget, and meets requirements(tastes good) all are required to produce a good yet cost-effective meal/product Systems Engineering Management
The Restaurant Analogy • INGREDIENTS - available technologies, funds, schedule, personnel, etc. • APPLIANCES - tools (e.g., software) for synthesizing, modeling, and analyzing a design. • KITCHEN - environment in which tools and communications are exercised (e.g., design room). • CHEF & ASSISTANTS - the systems engineering team. • RECIPE - the sequence of activities, tests, and refinements used to ensure the successful completion of the product • MEAL - the product that arrives on time, on budget, and meets requirements (tastes good) All are required to produce a good yet cost-effective meal/product Systems Engineering Management
Key elements of Systems Management Resources(margins) Resources provide the fuel. Holding margin ensures that fuel is available when you need it. Spend it sparingly and wisely. Very painful to get more later Scheduling Scheduling coordinates the various activities of the team to ensure that the team receives information and hardware when it is needed Scheduling identifies when and on what to spend resources (including allocating personnel)to ensure success when it is needed Prototyping Analysis and simulation only answer some questions. Others require actual testing in hardware. prototy ping can be a resource ffective element of the design process Systems Engineering Management
Key Elements of Systems Management • Resources (margins) – Resources provide the fuel. Holding margin ensures that fuel is available when you need it. Spend it sparingly and wisely. Very painful to get more later • Scheduling – Scheduling coordinates the various activities of the team to ensure that the team receives information and hardware when it is needed. Scheduling identifies when and on what to spend resources (including allocating personnel) to ensure success when it is needed. • Prototyping – Analysis and simulation only answer some questions. Others require actual testing in hardware. Prototyping can be a resourceeffective element of the design process. Systems Engineering Management
Key elements(cont · Communications Keep the team on the same page. Time spent by team members designing under old assumptions is a waste of resources Good communication with your customer(s)is essential in maintaining advocacy and access to resources assures that expectations do not drift Interfaces In larger projects, interfaces between groups/subsystems must be well-defined Two types of interfaces: physical and functional Interface violations will happen. Need to be arbitrated at next highest level Keep your interfaces to the outside world simple, clear, defined and consistent Systems Engineering Management
Key Elements (cont.) • Communications – Keep the team on the same page. Time spent by team members designing under old assumptions is a waste of resources. – Good communication with your customer(s) is essential in maintaining advocacy and access to resources. – Assures that expectations do not dri ft • Interfaces – In larger projects, interfaces between groups/subsystems must be well-defined. – Two types of interfaces: physical and functional. – Interface violations will happen.
