Software Development

Question 1

What are the seven phases of software development?

Answer 1

SDLC Phases (Software Development Life Cycle)

Planning and Analysis
Software/System Design
Implementation
Testing
Integration
Deployment
Maintenance

Question 2

What is the planning and analysis phase?

Answer 2

Goals determined, Needs of stakeholder assessed, High level planning

This is where a rough idea becomes a formulated plan

Question 3

What is the software/systems design phase?

Answer 3

Application or system is:

Defined
Outlined
Diagramed
Detailed

This is where focus on the overarching input/output of each function of the software are detailed.

Question 4

What is the implementation phase?

Answer 4

Programming and code is developed.

Question 5

What is the testing phase?

Answer 5

Formalized testing, Code checked

Question 6

What is the Integration phase?

Answer 6

Integration is testing the end to end services so that all the pieces/parts fit into the network, web server, databases, etc.

Question 7

What is the Deployment phase?

Answer 7

App is moved into production and people can use the software.

Question 8

What is the Maintenance phase?

Answer 8

Once the product is released, you have to focus on bug fixes, patches, tech support.

Question 9

What are the 3 parts of a Version Number?

Answer 9

10.0.12345

First number is the Major number (10)
Second number is the Minor number (0)
Last number is the Build Version number (12345)

Retired software is considered part of the Maintenance phase for CompTia. Most other models consider retirement its own phase.

Question 10

What is Agile software development model?

Answer 10

Software is developed in a time-boxed windows or “sprints” to allow more adaptivity to change.

Sprints are typically 2 week or 4 week time periods.

It uses similar phases to Waterfall model but does the much quicker.

Plan
Design
Develop
Test
Deploy
Review
Launch or return to Plan

Question 11

What is the Waterfall development model?

Answer 11

Project Planning
Requirements
Analysis
Design
Coding
Testing
Deployment

This is for very complex and require high levels of security. It takes a lot of time and doesn’t adapt to changes well.

Question 12

What is DevOps?

Answer 12

Software development and information tech operations.

This is where software developers and IT operations work closely together to speed up development.
