Chapter 6

Question 1

What is meant by the term systems engineering?

Answer 1

Interdisciplinary field of engineering primarily focused on how to successfully design, implement, evaluate, and make complex engineered systems over their life cycles

Question 2

Describe the systems engineering process in detail

Answer 2

Requirements for the system

System design

Sub-system development

System integration

System installation

System evolution

System retirement

Analysis of requirements, visibility analysis, functional analysis, throughout the life cycle.

Question 3

What is meant by the term model-based design

Answer 3

Mathematical and visual method of addressing problems associated with designing complex control, signal processing and communication systems, it uses a mathematical and visual method to represent something complex pertaining to software and hardware

Question 4

Give an example of a model-based design

Answer 4

Model-based design is a methodology applied in designing embedded software

Question 5

What is meant by the term model-driven design?

Answer 5

Model-driven architecture(MDA) is a software design approach for the development of software systems. It provides a set of guidelines for the structuring of specifications, which are expressed as models

Question 6

What is meant by the term life cycle?

Answer 6

process followed for software project, within a software organization. It consists of a detailed plan describing how to develop, maintain, replace, and alter or enhance specific software.

The life cycle defines a methodology for improving the quality of software and the overall development process

Question 7

Describe the life cycle process in detail

Answer 7

Planning, defining, designing, building, testing, deployment, then back to the top

Question 8

What is meant by the term constraint?

Answer 8

A limitation or restriction

Question 9

Give an example of a constraint

Answer 9

Design specs, capital(money), time

Question 10

What is meant by the term reliability analysis

Answer 10

What is the failure rate in time of a product or the failure rating time of a system. Ideally you want a flatline to be zero. Complexity drives reliability down, have more that can fail. Becomes an exercise of probability. Different industries and materials have different characteristics, they have specific reliability nature (its own way of failing)

Question 11

What is meant by the term maintainability?

Answer 11

Measures the ease and speed with which a system can be restored to operational status after a failure occurs

Question 12

What is meant by the term UML?

Answer 12

Unified Modeling Language - programming language that is used for object -oriented software development

Question 13

Example of UML

Answer 13

Model showing the multiple interactions that can happen at a store

Question 14

What is meant by the term quality function deployment?

Answer 14

Model for a product development and production. The model aids in translating customer needs and expectations into technical requirements by listening to the voice of the customer

Question 15

What is meant by the term model of the system?

Answer 15

An abstraction that tries to capture behavior and nature of a system

Question 16

Give an example of a model of a system

Answer 16

Life Cycle Model

Question 17

What is meant by the term re-evaluation?

Answer 17

Assessment, going back after the project. You go back and look at what went right, celebrating those things.

Looking at things that didn’t go well and ensure that they don’t happen again.

Question 18

Give an example of re-evaluation

Answer 18

Fishbone (Ishikawa) diagram

Question 19

What is meant by the term software engineering?

Answer 19

Software engineering is the process of analyzing user needs and designing, constructing, and testing end user applications that will satisfy these needs through the use of software programming languages

Question 20

What is meant by the term V-model

Answer 20

an SDLC model where execution of processes happens in a sequential manner in a V-shape

Linear process for software that organizes the development process in solid phases. Each phase must be completed so the next can begin

Question 21

Give an example of the V-model

Answer 21

Problem definition: concepts of operation, requirements/architecture, detailed design

Implementation

Project Test & Integration: Integration Test and verification, system verification/validation, operation/maintenance

Question 22

What is meant by the agile model?

Answer 22

Helps teams responds to unpredictability through incremental, iterative work cadences, known as sprints.

Principles:
Public, Client and employer, product, judgment, management, profession, colleagues, self
