Information technology
Information technology (IT) is the use of computers and telecommunications

equipment to store, retrieve, transmit and manipulate data.

Слайд 5

Software
Software is a collection of computer programs and related data that

provides the instructions for telling a computer what to do and how to do it.

Слайд 6

Software Development
Software development is the development of a software product which

consists of the next stages:
Problem analysis
Market research
Gathering requirements for the proposed business solution
Devising a plan or design for the software-based solution
Implementation of the software
Testing the software
Deployment
Maintenance

Слайд 7

Project
Project is a temporary endeavor undertaken to create a unique product,

service, or result.

Project can be further defined as temporary rather than permanent social systems or work systems that are constituted by teams within or across organizations to accomplish particular tasks under time constraints.

Слайд 8

Project Life Cycle
Initiating Processes
Planning Processes
Executing Processes
Closing Processes
Monitoring and Controlling Processes
Projects aim

to deliver software to specification

Слайд 9

Quality
European Headquarters – Lviv, Ukraine
Quality: the degree to which a system,

component, or process meets: - specified requirements
- customer or user needs or expectations

Qualitative project means project that has been finished in time, in required scope and within budget

Слайд 10

Quality Control
European Headquarters – Lviv, Ukraine
Software Quality Control is the set

of procedures used by organizations to:
- ensure that a software product will meet its quality goals at the best value to the customer,
- to continually improve the organization’s ability to produce software products in the future.

SDLC models
Waterfall
V-model
Agile\SCRUM
Software development life cycle is a division of software development

work into distinct phases or activities with the intent of better planning and management

Analysis

Design

Testing

Implementation

Слайд 13

SDLC models
The WATERFALL model is a sequential development approach, in which

development is seen as flowing steadily downwards through several phases

User requirements

System requirements

Global design

Detailed design

Implementation

Testing

Need, wish,
policy, low

Слайд 14

Waterfall
QC in Waterfall
Requirements: requirements that cover all scope are prepared by

Requirement Analyst once before Project starts
Preparation to Testing: once before Testing starts for all functionality
Testing: starts after Development phase completing.
Defects, if found, are logged and feedback provided to the implementation team to enable correction.
Product documentation, such as a user manual, is prepared, reviewed and published.

Слайд 15

Waterfall
Time spent early in the software production cycle can lead to

greater economy at later stages
Waterfall model places emphasis on documentation
Waterfall model has simple approach and is more disciplined
Easily identifiable milestones and deliverables
Track progress easily due to clear stages

Inflexible: difficult to respond to changing requirements
No working software is produced until late during the life cycle.
Some problems in requirements, deign and coding might be not discovered until system testing
Defects cost is high

Слайд 17

V-model
QC in V-model
Requirements: requirements that cover all scope are prepared by

Requirement Analyst once before Project starts.
QC validate requirements with respect to user needs, requirements, and business processes conducted.
Preparation to Testing: in parallel with other non-testers activities, such as Design (Global and Detailed) and Implementation (Coding)
Testing: starts after Development phase completing.
Defects, if found, are logged and feedback provided to the implementation team to enable correction.
Product documentation, such as a user manual, is prepared, reviewed and published.

Слайд 18

V-model
Time spent early in the software production cycle can lead to

greater economy at later stages
Easily identifiable milestones and deliverables
Testing activities like planning, test designing happens well before coding. This saves a lot of time
Proactive defect tracking – that is defects are found at early stages when they are introduced

Rigid and Inflexible: difficult to respond to changing requirements
If any changes happen mid way, not only the requirements documents but also the test Documentation needs to be updated
No working software is produced until late during the life cycle.

Слайд 19

SCRUM is an iterative and incremental agile software development framework

for managing product development.

Слайд 20

SCRUM
QC in SCRUM
Requirements: QC with Product Owner and Team work on

requirements continuously. Requirements can be not full and change very often.
QC engineers participate in requirements clarification and change.
QC engineers help Product Owner to develop better user stories with enhanced acceptance criteria.
Preparation to Testing: each Sprint for current Sprint.
Involve the whole Team into process of quality assurance and control.
Testing: starts simultaneously with Development phase.
Defects, if found, are logged and feedback provided to the implementation team to enable correction.
Product documentation, such as a user manual, is prepared, reviewed and published.

Слайд 21

SCRUM
Great emphasis on team work
Team learns and contributes throughout the process,

team becomes autonomous and strives for excellence
Iterative model leading to a delivery every sprint
Frequent and late changes welcoming
Creates an open environment and encourages immediate feedback

The basic premise that the team is committed to the project. If the team is not committed then process collapses
The size of the team is restricted due to the involvement of all team members
Reliance on experience
The management's comfort level in delegation of tasks
