how do you decide whether to build a
0:01
product piece by piece or improve it
0:03
gradually over time today we're breaking
0:05
down the incremental and iterative
0:07
models in project management to help you
0:09
decide when to use each one hi I'm

0:28
incremental versus iterative models
0:31
we'll look at how each model Works
0:33
explore their strengths and dive into
0:35
when to use them especially in agile and
0:37
hybrid project management settings let's
0:40
jump in all right first things first
0:42
let's define what each of these models
0:44
is all about with the incremental model
0:47
the project is divided into smaller
0:49
deliverable pieces called increments
0:52
each one adds a fully functional piece
0:54
to the final product so as you progress
0:56
each increment brings additional
0:58
functionality that stakeholders can
1:00
use the iterative model on the other
1:03
hand is more about Cycles instead of
1:06
delivering completed Parts each time
1:08
you're evolving the product through
1:09
repeated Cycles focusing on refining and
1:12
improving each version based on feedback
1:14
each cycle Builds on the last one so the
1:17
product slowly grows into its final form
1:20
with adjustments and enhancements along
1:22
the way what makes the incremental model
1:25
special well it's all about delivering
1:27
functionality in pieces one part at a
1:29
time each increment stands alone as a
1:31
functional piece of the project so
1:33
stakeholders see real usable progress
1:36
with every step and that's a major
1:38
advantage feedback happens as you go
1:40
helping shape the next increment based
1:42
on user input imagine you're developing
1:45
an e-commerce website using the
1:47
incremental approach you might first
1:49
build the shopping cart then add payment
1:51
processing and later the product catalog
1:54
each piece adds new functionality so
1:56
stakeholders can test interact and give
2:00
stage now let's talk about the iterative
2:02
model which is more about refining and
2:04
evolving here you're not delivering
2:06
individual parts that are ready to use
2:08
right away instead you're building the
2:11
entire product through repeated cycles
2:12
of improvement each iteration takes the
2:15
product closer to the end goal and this
2:17
approach is ideal when requirements
2:19
aren't fully clear at the start imagine
2:21
you're developing a new software feature
2:24
iteratively your first version might
2:26
just have the basic layout as you go
2:27
through each cycle you refine the user
2:29
interface add functionality and improve
2:32
performance until the feature meets all
2:34
expectations each iteration Builds on
2:36
the previous one so the product grows
2:38
into the final version rather than
2:40
arriving in chunks so when should you go
2:43
with incremental and when does iterative
2:45
make more sense the incremental model is
2:48
perfect when delivering completed and
2:50
functional Parts make sense if you're
2:52
working on a project with well-defined
2:54
steps and clear requirements incremental
2:56
development can bring early wins to
2:58
stakeholders because each piece adds
3:00
real value this model also works well if
3:02
there's a need for feedback along the
3:04
way but without constant changes to the
3:06
whole structure on the other hand the
3:09
iterative model is great for projects
3:11
where you don't have a full picture of
3:13
what the final product should look like
3:15
maybe the requirements are still
3:17
evolving or you're building something
3:19
Innovative and want to see how it
3:20
develops in those cases iterative Cycles
3:23
let you refine and improve based on
3:24
ongoing feedback you're learning and
3:26
adjusting with each iteration so by the
3:28
end you have a polished product that's
3:30
been shaped by trial error and
3:32
adaptation now let's go over some
3:35
benefits and challenges with each model
3:37
the incremental model shines in its
3:39
ability to deliver value early
3:41
stakeholders don't have to wait for the
3:42
entire project to see results they're
3:44
getting completed functionality with
3:46
every increment but on the flip side
3:48
this model requires clear requirements
3:50
Upfront for each increment to stay on
3:52
track the iterative model meanwhile
3:54
supports flexibility and continuous
3:56
Improvement since you're refining with
3:58
each cycle it's easy to adapt to
4:00
changing requirements however since each
4:02
iteration is a work in progress it may
4:05
not deliver fully functional Parts until
4:08
process if stakeholders need to see
4:10
complete sections early on iterative
4:12
alone might not be the best fit here's
4:14
where things get really interesting many
4:17
agile teams use a combination of both
4:19
incremental and iterative approaches and
4:21
it's actually a great way to get the
4:23
best of both worlds think about scrum
4:26
each Sprint can be seen as an increment
4:28
that delivers a functional part of the
4:29
process product at the same time each
4:31
Sprint includes iterative Cycles where
4:33
feedback is incorporated and adjustments
4:35
are made this combined model allows
4:38
teams to deliver something functional
4:40
quickly while also continually refining
4:42
and improving the product as they go
4:44
it's the perfect balance between
4:45
delivering early value and embracing
4:48
feedback if you're studying for the PMP
4:51
exam here's a quick way to spot the
4:53
differences if a question talks about
4:55
delivering complete Parts progressively
4:58
you're likely dealing with an
4:59
incremental approach but if the focus is
5:02
on evolving a single solution over time
5:04
with cycles of improvement then it's
5:06
pointing toward an iterative model also
5:09
remember incremental approaches work
5:11
well when requirements are clear and
5:13
defined while iterative models adapt
5:17
ambiguity to recap here's the core of
5:19
what we covered the incremental model
5:22
delivers completed parts of the project
5:24
in stages adding new functional
5:26
components each time this model is ideal
5:28
when you have clear requirements and
5:30
want stakeholders to see early value in
5:32
their project the iterative model is
5:35
about refinement and improvement over
5:36
repeated Cycles it's great for projects
5:39
with evolving requirements or Innovative
5:41
products that need adjustments along the
5:43
way and finally agile methodologies like
5:46
scrum off and use a blend of both to
5:48
deliver a functional product that keeps
5:50
improving with each Sprint It's the Best
5:52
of Both Worlds for teams looking to
5:54
deliver quickly and keep refining as
5:56
they go so there you have it the key
5:59
differences between the incremental and
6:00
iterative models and when to use each
6:03
whether you're prepping for the PM exam
6:06
or planning your next project
6:08
understanding these models can help you
6:10
pick the right approach and keep your
