Revisiting types of relationships between a program’s component projects

ABSTRACT 

In a previous paper I identified some twenty different types of relationships that can occur between a program’s interdependent component projects, derived from the literature. These were then classified into three main groups, based broadly on a classification of ways in which a program’s projects can be organized, proposed by Maylor et al 2006.

However, this particular way of classifying inter-project relationships did not appear to be particularly useful when I began to think about the management of such relationships. In addition, I wasn’t happy with some of my decisions about which group to put certain relationships into, which had a somewhat arbitrary element. I therefore looked for another way of grouping these relationships which might be more useful.

This paper develops a simple two-type classification of inter-project interdependencies, which I have termed transactional, and change-related. The management of transactional interdependencies covers the normal vicissitudes which invariably occur in the quite complicated environment of programs and their interdependent component projects. At a different level, change-related interdependencies include the management of significant changes in the program, and dealing with consequent escalated issues among the projects that comprise the program, including those which are often the subject of risk management activities.

Hopefully this simple two-type classification may be useful to those who may be interested in developing more detailed materials on the management of inter-project interdependencies.

INTRODUCTION

In a paper in PM World Today (Stretton 2012c), entitled Program management: Types of relationships between a program’s component projects, I began by noting that there is widespread agreement in the literature that a primary component of the program management task is the coordinated management of its related component projects. I then derived some twenty different types of relationships between component projects from four primary sources. These were then grouped into three categories (following a classification suggested by Maylor et al 2006) into predominantly independent projects, partially inter-dependent projects, and substantially inter-dependent projects.
