The SE Process:
-Establishes a common process framework for describing the life cycle of man-made systems
�Defines a set of processes and associated terminology for the full life cycle, including
conception, development, production, utilization, support, and retirement
�
The system engineer never has to be concerned with functions such as contracts and finance because that is the project managers roll
false
both ConOps and OpsCon are NOT considered systems thinking because they are strictly focused on the use of a system and not the overall system development
False
When stakeholders are in conflict it is only important to satisfy the one with a greater ability to impact the results of the system
False
TPM's must currently be satisfied to pass decision gate criteria and progress to the next lifecycle phase
False
It is considered best practiceto start incorporating design characteristics in thesystem architecture to expedite schedule
False
Due to the need for replicating the same SE process, tailoring is typically not permitted within an organization
False
Requirements can be represented as a hierarchy and broken down from the top to lower levels.
List the type of requirements in the hierarchy. The lowest level requirement has been provided.
-Stakeholder requirement
- System requirement
-Performance Requirement
- System Element Requirement
Identify what type of stakeholder each of the descriptions below represent
- Should be monitored by the project manager in case their status changes but which require almost no attention at that point in time
apathetic
Identify what type of stakeholder each of the descriptions below represent
- Need to be satisfied by the outcome of the project but who may not require regular attention during the project itself
Latent
Identify what type of stakeholder each of the descriptions below represent
-Will support the project and its aims and should be given regular updates to keep them included and motivated
defenders
Identify what type of stakeholder each of the descriptions below represent
- The stakeholder with the largest capacity to support the project within the business but also have the largest capacity to derail it if not carefully handled
promoter
During systems requirements definition you are not only defining requirements but also how those requirements will be
verified and validated
Overengineering something above and beyond requirements is defined as
Gold plating
Which SE model best supports an approach for continuing progress when requirements are unclear or yet to be fully developed
Incremental and iterative
What defines the evolution of a system, product, service, project or human made entity from conception through retirement
Lifecycle
System engineering and the technical process reduce what?
Risk
Drawing and diagrams are examples of design
Enablers
Which of the following would be considered a stakeholder of SMU
UNT board of directors
Which of the following are needed in defining your requirements
They need to be necessary, traceable, unambiguous, singular, cost effective, achievable and verifiable
Sequential Methods
In a sequence without feedback
�The plan progresses from left to right as a function of time
�Adheres to specified process
�Requirements>Design>Finished Product
Benefits of Sequential methods:
�Predictability
�Stability
�Repeatability
�High assurance
Waterfall Model
The most popular model. In this cycle, each phase must be completely finished before the next begins
Incremental and Iterative Methods
Allows a project to provide an initial capability, followed by successive deliveries,until the desired System of Interest is achieved
SE Lifecycle
Concept, development, production, utilization/support, retirement
Stakeholder
A person with an interest or concern
�Customer (Acquirer)
�Organization (Supplier)
�End-User
�Development team
Different stakeholders will have different needs
Kano Model
Basic Needs: Some needs make us unhappy if they are
not met, but don't make us happy if they are met.
-Tires included with a car
Performance Needs: Some needs make us steadily happier the more they are met.
�Horsepower, fuel economy,
Delighters: Some need
Requirements Derived from Needs
Requirements are formal structured statements that can be verified and validated
-Written in the form of "The who shall what"
-The cake shall be 10 ft
Goals
The word should can be used instead of shall to indicate a goal which must be addressed, but is not formally verified
�The cake should taste good
ConOps and OpsCon
Operational Concept (OpsCon)
-describes what the
system will do (not how) and why (rationale)
Concept of Operations (ConOps)
-addresses the leadership's
intended way of operating the
organization, use of one or more systems to advance the organization's g
Technical Measurements
MOE
- Measure of Effectiveness -
The metrics by which an acquirer will measure
satisfaction with products produced by the technical effort.
MOP
- Measure of Performance -
An engineering performance measure that
provides design requirements that are necess
Stakeholder Types
Low interest and low power -
apathetic stakeholders
- those who should be monitored by
the project manager in case their interest or power changes but which require almost no
attention at that point in time
�Low interest and high power -
latent stakeholde
Architecture Definition
Purpose
-Generate system architecture alternatives. Select alternatives that address stakeholder concerns and meet system requirements. Express in a set of consistent views
Function
- An activity or purpose
�This is why we have systems
Design Definition
HOW ARE WE GOING TO GET FROM ARCHITECTURE TO IMPLEMENTATION
Characteristics - shapes/ measurement/materials
Enablers - drawings, diagrams, metrics
