Quality Assurance
An Integral Part of Software
Systems Development Life Cycle
by MGD Services, Inc.
The QA Philosophy
The inherent philosophy of Quality
Assurance for software systems
development is to ensure the system
meets or exceeds the agreed upon
requirements of the end-users; thus
creating a high-quality, fully-functional
and user-friendly application
Quality Assurance
Is More Than Just Testing
Quality Assurance is involved in the entire
project development life cycle
Quality Assurance is a commitment by all
project participants to the Total Quality of the
Project
Quality Assurance Focus Early In Life Cycle

The QA Process Cycle
Phase I: Requirements Gathering,
Documentation and Agreement
Phase II: Establishing Project
Standards
Phase III: Test Planning
Phase IV: Test Case Development
Phase V: QA Testing
Phase VI: User Acceptance Testing
Phase VII: System Validation
Phase I:
Requirements and Project Scope
The system requirements are collected
and analyzed based on input and direction
from each of the project groups
The requirements documents are drafted,
reviewed, finalized and agreed upon by all
project participants
The scope of the project is established
and agreed upon
Phase II:
Establishing Project Standards
The QA team will assist in establishing
and setting the standards for the project
The standards will be established for:
Development Methodology
System Design
Quality Assurance Methodology
Methodology Compliance
Phase III:
Test Planning
The Quality Assurance Team will:
Write the Test Plans which detail the QA
involvement for the entire project life cycle
Develop test conditions based on the
business needs and business scenarios
Implement a defect-tracking mechanism
Phase III (con’t):
QA Methodology
The QA team will establish Quality
Assurance methods, practices and
standards
The overall QA methodology will assist
in creating a controlled product release
and greatly reduce the risk of errors
being introduced into the product
Phase IV:
Developing Test Cases
Write test cases that entirely test the
scenarios covered in the test conditions
Review the test conditions and
subsequent test cases with the project
users
Write test cases that will cover all
phases of the QA life cycle
Phase V:
QA Testing
QA Life Cycle consists of 5 types of
testing regimens:
1. Unit Testing
2. Functional Testing
3. System Integration Testing
4. Regression Testing
5. User Acceptance Testing
1. Unit Testing
The testing, by development, of the
application modules to verify each unit
(module) itself meets the accepted user
requirements and design and
development standards
2. Functional Testing
The testing of all the application’s
modules individually to ensure the
modules, as released from development
to QA, work together as designed and
meet the accepted user requirements
and system standards
3. System Integration
Testing
Testing of all of the application modules in
the same environment, database
instance, network and inter-related
applications, as it would function in
production. This includes security,
volume and stress testing
4. Regression Testing
This is the testing of each of the
application’s system builds to confirm
that all aspects of a system remain
functionally correct after program
modifications. Using automated
regression testing tools is the preferred
method
Testing Automation
MGD Services, Inc. Partners with the following
Automated Testing Tools Companies

Compuware

Phase VI:
User Acceptance Testing
(UAT)
The testing of the entire application by the
end-users ensuring the application
functions as set forth in the system
requirements documents and that the
system meets the business needs
Phase VII:
Validation
All systems should go through a validation
process which maintains the project
documentation library
Validation Documentation
All software systems that are developed
or used for FDA submissions are
subject to review by the FDA. All
phases of the Project Life Cycle are
required to maintain FDA validation
documents. MGD Services is
experienced in FDA Validation and 21
CFR Part 11.

managed, the QA process will bring the system
to production with cost and time savings.
