Purpose

The Project Breakdown Structure (PBS) defines all Work
Products, produced by a project.

The purpose is to first focus on what the project shall
produce, not the activities to perform.

Input & Output



INPUT

Product Requirements Specification

Project Breakdown Structure from earlier versions of the product and
previous projects, if available

Know-how from experienced personnel

Architecture

Organizational Demands
OUTPUT


Project Breakdown Structure including;

Technical Product Breakdown Structure

Management Product Breakdown Structure

Quality Product Breakdown Structure
The PBS is used as input when defining the Work Breakdown Structure
later in the planning process.

Work Products

A project always delivers tangible things like documents, code,
models, executables, plans etc. which all are Work Products.

Some examples;

Customer deliverables


Software components



design models, prototypes, tools etc.
Management artifacts


source code files, DLLs, executables etc.
Development components


software on a CD-ROM, user documentation etc.
plans, budgets, progress reports etc.
Quality assessment artifacts

test results, inspection reports etc.

Project Breakdown Structure

The Project Breakdown Structure should identify all Work
Products of the project and the final product.

The highest level represents the total set of Work
Products.

At the lowest level every Work Product is either a
Management Product, a Technical Product or a Quality
Product.

Management Work Products

© ABB AB, Corporate Research - 8

The Management Work Products are those that;

Assist in project management and control issues

Gives the answer to the business requirements
Typical Management Work Products are;

Requirement specifications

Project plans

Risk list

Status reports

Budget specification

Project (gate) assessments

Minutes of meetings
abb
Technical Work Products

© ABB AB, Corporate Research - 9

The Technical Work Products are;

Project deliverables, i.e. the final product

Intermediate products needed during development

The answer to the technical requirements
Typical Technical Work Products are;

Hardware and Software

User documentation

Prototypes

Design models

Education products

Testing products

Executables
abb
Quality Work Products

© ABB AB, Corporate Research - 10

The Quality Work Products;

Exists to define, assure, verify and record quality issues

Gives the answer to the quality requirements
Typical Quality Work Products are;

Test records

Inspection (review) records

Error (problem) reports

Follow-up reports

Summary

The Project Breakdown Structure is a tree structure reflecting the
Work Products on all levels produced by a project.

The Project Breakdown Structure should contain all the items
included in the final product, needed to build the final product and
needed to support the development of the final product.

The Work Breakdown Structure is later identified by defining what
activities are needed to produce the Work Products to the required
quality.
