STEPS TO HAVE A QUALTIY SYSTEM

• Quality Information Systems
• Quality Planning
• Quality Control
• Quality Assurance

3
QUALITY INFORMATION SYSTEMS

• Quality Information Systems consists of providing
  quality information during the life cycle of a
  project/product to all of the people involved
  such as the employees using the system and the
  customers involved.

4
Quality Information Systems Cont

• Quality Information Systems should allow for
  people who work on the project/product to be able
  to gain a quick knowledge about it
• Information should be able to be relayed quickly
  and accurately to customers
• Should help to improve the quality in all other
  areas of the project/product

5
Involved in Quality Information Systems

• Defining the necessary objectives of the system,
  for example through Quality Planning
• Users of the system need to be trained properly
  and have a good understanding of how the system
  works
• Integration of higher level systems
• Validation of the system, for example through
  Quality Control
• Ongoing support and maintenance, for example
  through Quality Assurance

6
Quality Planning

• Quality Planning is setting the objectives for a
  product/process and then planning the means in
  which to reach to those objectives

7
Quality Control

• Quality Control should be involved within the
  users daily work.
• Must be done efficiently and accurately
• Also through validation

8
Quality Assurance

• Quality Assurance gives the confidence that a
  project/product conforms to a certain level of
  quality, and continues to have quality
  improvement.

9
Effective Quality Assurance

• Quality Audits
• A constant flow of information about the
  product/project
• Having an effective process

10
Critical Success Factors

• -Emphasize the prevention of quality problems,
  rather than concentrate only on detection and
  correction of these problems
• -Facilitate awareness of and learning by the user
  of the quality system with respect to product and
  process quality
• -Focus on continuous quality improvement, rather
  than on attaining a fixed level of quality

11
Critical Success Factors(continued)

• Make quality measurable
• Operate efficiently in order to prevent
  distortion of daily work
• (integrate information system into users primary
  process)
• Give guidelines for the interaction between the
  supplier and purchaser of a good, both during the
  initial phases and during the development process
  

12
Potential Problems In Setting Up A Quality System

• ISO 9000 and ISO900-3
• Identifying and Correcting of Problems
• Quality Improvement and Learning
• Measuring Quality
• Overhead is Large
• Lack of Support
• Guidelines for Interaction

13
ISO 9000 and IS0 9000-3

• ISO 9000 Standards meant to cover entire range
  of organizations
• ISO 9000-3 Standards meant for companies
  producing software
• Causes standards to be very generalized

14
Identifying and Correcting of Problems

• Preventative Measures
• High Failure Costs

15
Quality Improvement and Learning

• Guidelines focus on attaining level of quality
  defined by users of the Quality System
• 3 Negative Consequences
• Defined level may be low
• No Preventative Action
• No Continuous Improvement

16
Measuring Quality

• Software is still active area of research
• Difficult to implement in practice

17
Overhead is Large

• Every process, action, problem, correction, etc.
  must be documented
• Quality System cannot just be placed on top of
  the current way of working

18
Lack of Support

• ISO guidelines offer no tools to provide
  different rules and standards for different
  processes
• Example One uses different types of production
  organization, multiple development methodologies,
  and has different customers There is no support

19
Guidelines of Interaction

• Guidelines for supplier and purchaser, but very
  little for interaction between the two
• One of main purposes should be closer cooperation
  between business partners
• Good Communication
• Goal selection
• Selecting acceptable level of risk
