Option a)Drink 120 bottles wine in 10 years; all from Rioja Reserva.

Option b)Dring 36 bottles wine in 3 years;

12 Spanish, 12 French, and 12 Italian.



My project is unique.

At the end it worked.

Knowing when to stop and where to start



Incorporation of change in practice

Adoption of “new” in space industry

Systems engineering

Facilitation mechanisms



We can, but we don’t want to.

We can’t, and we dont know how to get there or can’t afford

the expense to do so.

The way we’ve done it has always been fine

Driven by tradition and inertia: loss of vital

knowledge and vitality

Developments based on what is expected to be done

and not on what needs to be done

Customers Manufacturers

Engineers

Understand the meaning of risk

Increase solution tradespace

Focus on solution, not on contract

fulfillment

Systems engineering is a discipline

All

Align the letter to the spirit



Get buy-in for concepts

Demonstrate usability

Get people… to use it correctly and consistently

Knowledge and skills

Exposure and ability to learn

Successful experiences and ability to influence success

Design maturity vs documentation delivery

Cost, schedule and perfor. vs innovation and complexity

Efficiency and effectiveness vs firefighting

Process improvement vs process fulfillment

Increase refresh rates
