Prioritization of Tests

Prioritization of Tests :

Why do we need to Prioritize ?

1.  Time constraints
2.  Resource Constraints
3.  We need to get the best done in the time available
4. How do we Prioritize?
5. Identification of the Most Important Tests first(MITs)

Basis of Prioritization of Tests:

1.  Business complexity.
2.  Severity of potential failure
3.  Visibility of failure
4.  Likelihood of error
5.  User requirements and priorities
6.  Technical complexity and complexity
7.  Contractual requirements / Compliance requirement

What is Quality Management, Quality Control & Quality Assurance ?

Quality Management: Responsible choosing the correct process to ensure that the product is ‘fit for purpose’.

• A predictable degree of uniformity and dependability at low cost and
• suited to the market (Dr. Edward Deming).
• Degree to which a set of inherit character tics fulfills the requirements
• (ISO-9000)
• Meeting the customer requirements first time and every time which is fit
• for use to its intended functions with reasonable cost and within in time.
• Quality must be measurable and should predictable.
• Quality must be well defined and should be quantified
• Quality objective should be achievable and traceable.
• Quality is Value , Value = Utility (Fit for Purpose) + Warranty (Fit for Use)
• Utility = What customer wants / Warranty = How it is delivered.
• ISO9126 – Quality Standard ( The standard is divided into four parts : Quality model , Internal metrics, External metrics , Quality in use metrics)

Quality Control : “ is the activity performed to ensue that a Product is ‘fit for Purpose’ “.

1. Concentrates on specific products.
2. Defect – detection and correction oriented.
3. Usually done after the product is built.
4. This is usually a line function.
5. Examples : Software testing at various levels.

Quality Assurance: “is the activity performed to test the process is being followed”
1. Concentrates on the process of producing the products
2. Defect – prevention oriented
3. Usually done throughout the life cycle.
4. This is usually a staff function.
5. Examples : Reviews and Audits
