Likewise, tasks don’t work by way of a vacuum and it’s almost not possible to discover a process that isn’t depending on a number of duties aside from the primary one.

Whether or not the output of 1 process impacts the initialization of the second process, otherwise you may simply have to attend for the assets to be assembled earlier than establishing the duty — understanding and pull by way of this is without doubt one of the most essential assignments of a undertaking supervisor.

On this article, our emphasis can be on the significance of dependency administration and the way undertaking managers ought to stroll by way of totally different classes and varieties of dependency quite than the undertaking administration instruments to look out for.

Undertaking Dependency

In undertaking administration, we have to handle and schedule the duties whereas listening to their sequence and necessities to hold ahead the undertaking easily.

As an example, if process X must be accomplished to start out process Y, we are going to say that process Y depends on the likes of process X. This can be a easy instance, though it may well get complicated in multipart tasks with codependent duties.

Some essential phrases that go together with dependencies in undertaking administration are defined beneath:


In undertaking administration, constraints are as common as a dependency and might be mentioned to have a cause-effect relationship. These are the constraints {that a} undertaking supervisor must abide by whereas managing a undertaking.

Three major constraints that any undertaking faces are the time, value, and scope of the undertaking. They’re often known as the triple constraint.

Dependency management; time, cost and scope

Value: Budgetary constraints of the undertaking

Time: Projected timeframe for completion of the undertaking

Scope: All duties to be accomplished to finish the undertaking

For efficiently finishing a undertaking, the undertaking supervisor should monitor its constraints and dependencies attentively and (re)allocate assets if and when wanted.

Lead and Lag


Lag might be outlined because the time length whereby a mentioned successor exercise is required to be delayed concerning the predecessor exercise. Merely placing, it’s the delay between two scheduled actions; for example, if process A completes and there comes a delay earlier than process B begins, it’s known as a lag.


Lead is a situation outlined because the time length whereby a mentioned successor exercise might be accelerated or superior concerning the predecessor exercise. In less complicated phrases, if the second exercise is began while the primary exercise continues to be being run, it’s known as lead time. As an example, let’s assume that the time required to finish process F is 10 days, and it’s 12 days for process G. On the 8th day of process F, we begin process G; due to this fact, process G has a lead time of two days.

Vital Path

This sequence of continued actions which can be chained with a view to full a undertaking is named the crucial path of the undertaking. You will need to be aware {that a} delay in any process on this sequence can delay the whole undertaking until the hole is fastened by way of lead time.

Classes of Undertaking Dependency

The next sorts will allow you to perceive the connection between dependencies:

End to Begin (FtS) Dependency states that Job T can’t be began with out the completion of Job S.

FTS Dependency management

End to End (FtF) Dependency states that Job S can solely be accomplished when Job T ends.

FTF Dependency Management

Begin to Begin (StS) Dependency states that Job T can’t be began until Job S begins.

STS Dependency Management

Begin to End (StF) Dependency states that Job T has to start out for Job S to be accomplished.

STF Dependency Management

Dependency Administration

A apply used to determine, resolve, and use the undertaking’s dependencies in a programmed method is named dependency administration.

Significance of Dependency Administration

If the undertaking dependencies aren’t managed in the suitable method or in time, the whole undertaking can lose its integrity.

As an example, what occurs in case you don’t allocate assets immediately for the completion of a process that’s delayed as a result of its predecessor didn’t full it on time?
