Concepts and software quality assurance

1. Software Quality Models

   • Product quality
     • properties according to the client
   • Quality of the process
     • activities that influence the software
   • Quality in use
     • environment where it is used

2. ISO Quality Standards

   • ISO 12207
     • serves for software life cycle models.
     • The standard comprises 17 processes
     • groups the activities during the life cycle
   • Norma ISO/IEC 9126
     • standard for evaluating software products,
     • indicates quality characteristics
     • indicates guidelines for its use
     • shows a set of 4 characteristics
       • effectiveness
       • productivity
       • integrity
       • satisfaction
   • Estándar ISO/IEC 14598
     • used for software product evaluation
     • evaluation process
       • Repeatability
       • Reproducibility
       • Impartiality
       • Objectivity
       • phases involved
         • Analysis of evaluation requirements
         • Evaluation of specifications
         • Design evaluation
         • Implementation of the evaluation plan
         • Evaluation of the conclusion
     • In addition, 6 parts are defined
       • ISO/IEC 14598-2

       • ISO/IEC 14598-6
         • Documentation of Modules

3. SPICE

   • is an important international initiative standard
   • support the development of a Software Process
   • has three main objectives
     • Develop a work project for a standard
     • To carry out the tests
     • To promote technology transfer
   • offers the following benefits to industry and users
     • supports software development
     • software vendors undergo evaluation
     • tools to start
     • continuous improvement process

4. CMMI

   • It is a model of process improvement
   • provides elements to determine the effectiveness
   • evaluate the effectiveness of current processes
   • establishes five levels of maturity
     • Level 1
       • Starting or executing
     • Level 2
       • Repeatable
     • Level 3
       • Defined
     • Level 4
       • Managed
     • Level 5
       • Optimized

5. PSP

   • (personal software process)
   • a method of self-knowledge
   • allows to estimate the time in making an application
   • used to calculate the budget
   • is used for small programs
   • is for personal use

6. TSP

   • (Team Software Process)
   • method to improve teamwork
   • for high performance equipment
   • improves software quality
   • reduces costs
