PROJECT SCOPE & CONCEPT OF OPERATIONS
JANUARY 21, 2016
DEFINING THE SCOPE
• Required to develop good requirements
• What defines the scope
• Needs, Goals, and Objectives
• Identify stakeholders, i.e., partners, collaborators, those with the money
• Develop operational concepts
• Know and understand the constraints
• Are there pre-­‐existing documents that pertain
• Presidential directives
• Announcement of Opportunities
• Proposals
DEFINITIONS
• Needs: explains why the stakeholder wants this project developed
• Goals: the fundamental target you must accomplish to fulfill the need
• Objectives: initiatives that implement the goal.
• What is the minimum the stakeholders expect for the system to be successful?
• Example: Apollo Program
• Need: Counter Soviet military threat
• Goal: Demonstrate American technological superiority
• Objective: Make a decisive move in the conquest of space.
• Operational Concept: Launch crew. Lander, … etc.
• Assumptions: All technology needs are achievable
• Constraints: Do it within the decade and use American-­‐made components
• Authority & Responsibility: NASA is responsible for carrying out the mission
CONCEPT OF OPERATIONS -­‐ CONOPS
• ConOps: a description of how the system will be operated during the mission phases in order to meet stakeholder expectations.
• Why is a ConOps important?
• Easy to understand – everyone can relate to it (even the customer)
• Provides an operational perspective
• Stimulates requirements development
