Stakeholders 8 Who’s paying?
9 Mission stakeholders change as a mission progresses Life-Cycle Stage Example Stakeholders Pre-Phase A NASA Headquarters, NASA Centers, Presidential Directives, NASA advisory committees, the National Academy of Sciences Phase A Mission Directorate, customer, potential users, engineering disciplines, safety organization Phase B Customer, engineering disciplines, safety, crew, operations, logistics, production facilities, suppliers, principle investigators Phase C Customer, engineering disciplines, safety, crew, operations, logistics, production facilities, suppliers, principle investigators Phase D Customer, engineering disciplines, safety, crew, operations, training, logistics, verification team, Flight Readiness Board members Phase E Customer, system managers, operations, safety, logistics, sustaining team, crew, principle investigators, users Phase F Customer, NASA Headquarters, operators, safety, planetary protection, public From: NASA Systems Engineering Handbook , NASA SP-2016-6105 Rev2, 2016 Stakeholder: A group or individual who is affected by or has an interest or stake in a program or project. There are two main classes of stakeholders: customers and other interested parties .

14 MOEs and MOPs Measures of Effectiveness (MOEs) are metrics by which the stakeholders will assess their satisfaction with the system or product we sometimes call this the voice of the customer MOPs help tell us if we are doing things right MOEs help tell us if we are doing the right things Measures of Performance (MOPs) are criteria that describe system performance and are derived from attributes inherit in the each design (e.g. mass, cost, design life, reliability, etc) we sometimes call this the voice of the engineer

16 Decisions made early disproportionally impact life cycle costs From: NASA Systems Engineering Handbook , NASA SP-2016-6105 Rev2, 2016. Gruhl’s Rule (1980/90s) Overruns are very likely if phases A and B are underfunded! (i.e. don’t do tomorrow what you can do today!)
17 Architecture Definition(s) “The structure of components , their relationships , and the principles and guidelines governing their design and evolution over time.” Department of Defense (DOD) Integrated Architecture Panel, based on IEEE STD 610.12 “An architecture is the fundamental organization of a system embodied in its components, their relationships to each other, and to the environment, and the principles guiding its design and evolution.” IEEE STD 1471-2000 “It is the fundamental and unifying system structure defined in terms of system elements, interfaces, processes, constraints, and behaviors.” International Council on Systems Engineering (INCOSE) System Architecture Working Group
18 Example: wildfire detection satellite Includes all the mission elements: launch, satellite, ground operations, user/subject.

19 Brainstorming to get ideas Brainstorming: A group activity/technique used to generate ideas in a creative and non-threatening environment. Rules and suggestions for effective brainstorming 1. No destructive criticism of ideas is allowed. 2. Encourage creative, wild, or ridiculous ideas. They may eventually lead to a solution that would not have otherwise been developed. 3. Provide as many ideas as possible in a short period of time. 4. Group members should share all their ideas without constraint. 5. Ideas suggested by one group member should be expanded upon by other group members. 6. A group facilitator records ideas and enforces brainstorming rules 7. Read, read, and read again!
20 Organizing ideas with a Morphological Matrix Given a prohibitively large number of possible options, how do we determine which ones to evaluate and compare? Morphological Matrix Purpose : to organize results of brainstorming activity, help discover overlooked alternatives, spur additional creativity, and to identify possible new combinations for a system A functional and structured means of decomposing a system or product and identifying options Procedure: 1. Functionally decompose the existing system or product 2. For each function, list all the possible ways in which it might be satisfied 3. Organize into a Morphological Matrix 4. Examine the matrix for overlooked alternatives or possible new concept permutations

23 Concept Down Selection Identify need Collect ideas Generate concepts Concept down-select New concepts added Candidate concepts selected Concepts added Concept down-selection Brainstorming helps generate many possible concepts Assessing these concepts eliminates some alternatives New ideas may emerge based on the first brainstorming and down- selection cycle Repeat this process as many times as necessary until you converge on a final set of designs that will be carried forward for more detailed analysis

30 The ConOps Diagram (OV-1) A ConOps is a diagram (or document) that provides a summary view of a chosen design solution to satisfy mission objectives. The ConOps diagram is used to communicate the qualitative and quantitative system characteristics to all mission stakeholders. ConOps should capture all the essential features of accomplishing the mission. ConOps is an important part of gaining support for a proposed mission.

31 The ConOps Diagram (OV-1) The OV-1 should provide high-level insight into the major architectural elements of the mission: What launch vehicle is being used? How many flight systems are being deployed? What is the planned orbit or trajectory? What is being observed or demonstrated? What tracking stations are being used? Where is the mission ops center located? What communication paths are required?
