Pooled, Sequential & Reciprocal dependence

Revision as of 13:59, 2 March 2023

Motivation An article on this topic already exists on the wiki. However, I believe I can improve/supplement this article on a number of points: 1) Elaborate on the application potential of the different types of dependencies. 2) Supplement the original theory, from James D. Thomson’s Organizations in Action, with today’s perspective on it (how the theory has evolved). 3) Take the theory from its original focus on project management and discuss its application potential on program and portfolio management levels. 4) Describe dependencies’ ability to work as a Risk Management tool

The topic is highly relevant to our case, and I hope this can be used to write a better article as well as prove useful on the case work.

Abstract (Draft)

A project consists of a series of tasks that need to be executed in order to complete it. The way these tasks are arranged in relation to each other will come down to their dependence. According to James D. Thompson, task dependence can be distinguished into three types: Pooled, Sequential and Reciprocal. For a Project Manager dependencies can be a powerful tool in managing the complexity of a project. Using dependencies to characterise tasks in a project will help to determine the sequence of which tasks should be completed in order to optimise time use, resources, workers, etc. A way dependencies are not used much yet is on the levels above project management, namely program and portfolio management. Here, dependencies could prove useful in terms of optimising efficiency in a program or portfolio setting, spanning across several projects. All this will be explored in greater detail and described in the article.

Big Idea

REMOVE:: Introduction to J. D. Thompson’s “Organizations in Action”, and the origin of three dependency types: Pooled, Sequential and Reciprocal.

Complexity

A project consists of a series of interdependent tasks. These need to be completed in a certain manner which is determined by each task’s link(s) to other tasks. In this way, a project can be seen as a dynamic system where factors such as the number of tasks, their interconnectivity, uncertainty and ambiguity makes up a projects degree of complexity.^[1] A Project Managers ability to manage this complexity, in any variable shape or form it might take, is crucial for a projects chance of success. Tools that help deal with the different factors of complexity are therefore important for Project Managers to know about.

One such tool is the three types of interdependence, defined by J.D. Thompson in 1967.

J.D. Thompson and Organizations in Action

NOTES: While J.D. Thompson’s original theory on Pooled, Sequential and Reciprocal interdependence were targeted organisational structures, the theory can be applied to any type of “body” that consists of interconnected elements and tasks, such as projects, programs and portfolios. For the sake of the course and to ensure high relevancy to the reader, the theory will be applied to a project level instead of organisational structures. In later sections, this will be expanded to program and portfolio levels as well.

Purpose

• Improve resource management
• Improve resource efficiency
• Mitigate uncertainties (time management)
• Mitigate risk (Less uncertainty)

Types of interdependencies

Fig. XX Model of Pooled Interdependence in a project

As described in the ”Complexity” section, projects consists of a number of tasks with varying degrees of interdependence between each other. This does not entail that all tasks are directly connected. What is meant by interdependence is that all tasks in a project works towards a common objective^[2] and if one task fails it might impact the changes of success for that objective, thereby impacting all tasks connected to it^[3].

For a project manager it is necessary to be able to address these interdependencies and use them to structure the tasks of a project. First step towards this is being able to distinguish and identify different types of interdependencies, and subsequently know how to handle tasks depending on which type they are. J.D. Thompson defined three types of interdependencies which will be further described in the sections below. As it has been quite a while since the J.D. Thompsons original theory was published for the first time, the field of interdependence has been expanded upon. Some of these additions (INSERT EXAMPLES) to the theory will also be described.

Pooled interdependency

Of the three types of interdependencies that J.D. Thompson defines, pooled interdependence is the simplest. When a project contains a series of tasks of which non of them are directly connected or dependent on each other, these tasks are still working towards a common deliverable. Therefore, each of the tasks are still indirectly dependent on that the other tasks are completed, as the projects end deliverable will not be achieved otherwise. Every task works independently towards completing a common goal. Cite error: Invalid <ref> tag; refs with no content must have a name To give an example,

Sequential interdependency

Reciprocal interdependency

Other interdependencies

• Benefit interdependencies
• Risk interdependencies
• Financial interdependencies
• Outcome interdependencies
• Schedule interdependencies
• Resource interdependencies

Application

Project level

OBS: The following sections are placeholders - There appears to be a valid argument for distinguishing between applying dependencies on the 3P’s of management, but whether these are different enough to justify their own header is not yet clear.

Program level

Benefits:

• Tracking of benefit realisation across projects —> Program Management Performance Domains (PMI standard)

Portfolio level

Benefits:

• Strategic portfolio management (Good for overview —> Going from goal to action)
• Use in portfolio governance

Optimising processes

Applying interdependencies in other settings

Looking at how to apply the theory on a project, program and portfolio level in various types of companies.

Limitations

A look into how the field have developed since the original introduction in 1967. How the old theory falls short (Lack of depth and distinguish between the three original types of dependency)
