Quality Information Systems

Quality Planning

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.

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 itInformation should be able to be relayed quickly and accurately to customersShould help to improve the quality in all other areas of the project/product

Involved in Quality Information Systems

Defining the necessary objectives of the system, for example through Quality PlanningUsers of the system need to be trained properly and have a good understanding of how the system worksIntegration of higher level systems Validation of the system, for example through Quality ControlOngoing support and maintenance, for example through Quality Assurance

Quality Planning

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

Quality Control

Quality Control should be involved within the users daily work.

Must be done efficiently and accurately

Also through validation

Quality Assurance

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

Effective Quality Assurance

Quality Audits

A constant flow of information about the product/project

Having an effective process

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

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

Potential Problems In Setting Up A Quality

SystemISO 9000 and ISO900-3Identifying and Correcting of ProblemsQuality Improvement and LearningMeasuring QualityOverhead is LargeLack of SupportGuidelines for Interaction

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

Identifying and Correcting of Problems

Preventative Measures

High Failure Costs

Quality Improvement and Learning

Guidelines focus on attaining level of quality defined by users of the Quality System

3 Negative ConsequencesDefined level may be lowNo Preventative ActionNo Continuous Improvement

Measuring Quality

Software is still active area of research

Difficult to implement in practice

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

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

Guidelines of Interaction

Guidelines for supplier and purchaser, but very little for interaction between the twoOne of main purposes should be closer cooperation between business partnersGood CommunicationGoal selectionSelecting acceptable level of risk
