Why Quality ?

• In December 1999
• Both India and Brazil are mounting intensive
  campaigns to nurture a world-class software
  industry.
• Their competitive advantage will be quality..."

Quality Branches

• The Quality should be In
• The quality of the process which results in the
  product
• The quality of the product,
• The quality in the context of the business

Software Quality via Better Processes

• Total Quality Management
• Quality is the responsibility of the management.
• Defects, if present, are caused by the system,
  rather than the workers.

Software Quality via Better Processes

• The ISO 9000 Standard
• International set of standards for quality
  management
• Quality standards and procedures should be
  documented in an organisational quality manual

Software Quality via Better Processes

• Capability Maturity Model
• Initial. Ad-hoc management is performed when
  sudden crises occur.
• Repeatable. There are a set of process standards
  that could be employed to repeat earlier types of
  projects.
• Defined. Organizations in this level have clearly
  defined, well-documented procedures for process
  control

Software Quality via Better Processes

• Capability Maturity Model
• Managed. The software process is understood
  thoroughly and metrics are collected to
  constantly monitor and control the quality of the
  process.
• Optimizing. At this level, the metrics are
  analyzed and feedback is provided to enhance the
  quality of the process.

Software Quality via Better Business
Environment
Brazil aims to achieve international standards on
quality and productivity in the software sector.
The share of software in the overall Brazilian IT
industry has been advancing in the last eleven
years, going from 15 in 1991 to 25 in 2001.

Software Quality via Better Business
Environment

• Institutional Relationships
• There is a strong cooperation among the Brazilian
  universities-companies-government in the software
  quality area.
• There are increasing in the number of Computer
  Science departments in Brazilian universities
  which has software quality as an important
  research topic.

Software Quality via Better Product

• Product-Based view
• It considers that quality is dependent on..
• The inherent characteristics of a product.
• It can be quantified based on the presence or
  absence of a number of attributes.
• METRICS

MASTER

Software Quality via Better Product

• Quality Factors
• It defines some key characteristic that a product
  would exhibit.
• Quality Metrics
• It denotes a measure that can be used to quantify
  the criterion.

Quality Metrics

• Choice of Metrics
• A valid metric is that which has the capability
  to measure the intended parameter
• It depends on the stage that we deal with.
