In
today´s post we are going to focus on Project Management. More and
more, we see in Supply Chain the need to step back from the
operational day to day task and focus on a specific project with a
clear starting and end date. However there are several methodologies
that can be followed to ensure the best outcome for any given
project. We will be focusing on the two most common: Waterfall and
Agile.
The
Waterfall method is the most traditional project management approach
that uses sequential phases to define, build, test, and release
project deliverables. Each phase is completed and approved before the
team moves on to the next phase. The project can't move backwards to
previous phases.
On
the other hand, Agile is an umbrella term covering several newer
project management approaches that use iterative work cycles, called
sprints. Each sprint uses 'mini-phases' to define, build, test, and
release the project deliverables.
The main difference between waterfall and agile methods is in the goals; the waterfall method wants to get everything right the first time, and agile methods want to get things released quickly.
Pros of the waterfall method
-
Potential issues that would have been found during development can
be researched and bottomed out during the design phase.
-
The development process tends to be better documented since this
methodology places greater emphasis on documentation.
-
Because the waterfall process is a linear one it is perhaps easier
to understand. Often teams feel more comfortable with this approach.
Cons of the waterfall method
-
Often it´s not known exactly what it´s needed up front or what’s
possible with the technology available.
-
Changes to requirements can’t easily be incorporated with the
waterfall method and there are often laborious change control
procedures to go through when this happens
-
The process doesn’t have its own momentum
Pros of Agile methods
-
Much more quicker, and successive iterations can be delivered
frequently, at a consistent pace.
-
There is closer collaboration between project managers and the
business.
-
Changes to requirements can be incorporated at any point of the
process.
-
It gives the opportunity for continuous improvement for live
systems.
-
It is highly transparent.
Cons of Agile methods
-
Agile methodologies are often more difficult to understand than
linear, sequential ones.
-
Because of the emphasis on working software there can be a
perception that documentation can sometimes be neglected.
-
When implemented badly Agile can introduce extra inefficiencies in
large organizations or can be working against long standing
organizational processes.
