Defects analysis

The following article is a sample from the full BVOP™ Ultimate Guide and is part of the preparation for the BVOP™'s modern Agile Project Management Certification Program.

The BVOP present defect analysis as a practice and tool for analyzing problems in development teams, organization, management practices, environment, or other factors causing product defects.

A defect may refer to issue, bug, incident, error, flaw, failure, malfunction. The common understanding of a defect is an incorrect or unexpected result or behavior of the product.

The BVOP suggest defining categories for all defects, investigating the root causes for their occurrence, and adding each defect to a suitable category.

Defects categories

Defects categories may include:

  • Time pressure
  • General Stress
  • Scope misunderstanding
  • Scope change
  • Poor requirements
  • Lack of communication

Time pressure

Time pressure may be a reason for the occurrence of defects. When teams are pressed by deadlines they may miss important details or work quality may drop.

If defects in this category are predominant, this may be an indication of too short deadlines.

Corrective actions to reduce future defects in this category may include revisions and negotiations on deadlines.

General Stress

Stress may be the cause of defects. When people are under stress, productivity, proactivity, and confidence are declining. It is important that the defects in this category are distinguished from the Time Pressure category.

Causes of general stress may vary, but general ones may include:

  • Management attitude
  • Personal conflicts
  • Cultural differences
  • Organizational policy
  • Organizational stability
  • Environment

Representatives of the BVOPM office are the main initiators to involve all the offices and their representatives in solving the problems.

Scope misunderstanding

If the scope of the project is not communicated enough at early planning stages or details are missing this may lead to many defects categorized in this category at later development or implementation stages.

Another reason for the defects in this category may be not enough knowledge of the matter and technical or business knowledge among the key roles involved in the project.

Corrective actions to reduce the defects in this category may include re-discussing the details of the project scope, training in technology, and familiarizing key roles with the business logic of the project.

Scope change

Defects in this category may reveal problems in multiple areas such as:

  • Clients or users are not aware enough of their needs.
  • Development or implementation progress is slower than the users' demand.
  • Lack of resources or introduced optimizations has changed the scope of the project.
  • Additional requests from users or stakeholders that may not be actually needed.

Poor requirements

Defects in this category may be caused by a deficiency of:

  • Detailing
  • Quality documentation
  • Technical or design expertise
  • Documented verbal agreements

Corrective actions to reduce the defects in this category can be sessions between team members discussing the requirements before the actual work and potential improvement of requirements.

Creating sketches, diagrams, animations, or functional prototypes from product developers that present the work needed to be developed can be a validation method along with the demanding party.

Lack of communication

Communication is very important for any project, development and business initiative. Lack of communication may relate to:

  • General slow communication
  • Intentionally ignoring important topics
  • Missing important contexts
  • Virtual or distant teams
  • Low employee morale
  • Conflicts

The BVOPM office investigates the core reasons for the problems and spends effort in resolving them. The categories with the highest number of defects should take higher attention.
