The Agile vs Scrum debate is one which has puzzled even essentially the most skilled undertaking managers. Typically, these two ideas are used interchangeably, however in actuality they’re two various things. In apply, utilizing Agile and Scrum in an analogous method won’t end in bother, however it is perhaps deceptive. With a purpose to keep away from any confusion all through the phases of product improvement, it’s best to make use of the proper terminology. This won’t solely keep away from confusion. It would additionally assist software program improvement groups acquire a greater understanding of the underlying rules of standard software program improvement methodologies, and enhance when it comes to effectivity and productiveness because of this.

On this submit we talk about the distinction between Agile and Scrum so that you just take advantage of every of them all through the software program improvement course of.
What Is a Challenge Administration Methodology?
Earlier than addressing the Agile vs Scrum debate, it is very important perceive what a undertaking administration methodology is. In short, a undertaking administration methodology is a mixture of strategies, processes, and practices that decide one of the simplest ways to method a undertaking all through its totally different phases, from begin to end.
In time, such methodologies have turn out to be a helpful manner to assist assure that complicated endeavors finish on a optimistic word. With out them, it could be very laborious for undertaking managers to maintain observe of all the pieces that is occurring. A fancy undertaking requires monitoring and ensuring that folks, price range, supplies, time, and different assets are managed accurately.
Software program improvement isn’t any exception to this. As software program tasks turn out to be extra complicated, builders and undertaking managers have seen an rising stage of undertaking complexity that calls for them to implement state-of-the-art administration instruments.
That is the place Agile and Scrum present up. Nonetheless, earlier than diving into their traits, it’s first needed to grasp the precursor of Agile: the Waterfall methodology.
The Waterfall Methodology
The Waterfall methodology, also known as the Waterfall mannequin, is likely one of the most generally used undertaking administration methodologies of all time. Software program improvement tasks adopted this similar method for a few years, however finally, it turned problematic. As the extent of software program improvement complexity elevated, builders discovered waterfall to be very restrictive.
On this technique, a undertaking is commonly approached when it comes to phases and actions, and every one will solely begin as soon as the earlier one has already been accomplished, thus the identify Waterfall. That is inconvenient for varied causes. For one, it approaches tasks in a linear, sequential, and rigid manner. Secondly, it isn’t optimum when it comes to a undertaking’s assets and the way they’re used. Lastly, it’s problematic for tasks that require excessive ranges of interconnectedness throughout groups. For this and different causes, software program builders determined to take a unique method.
The Agile Philosophy
Greater than a undertaking administration methodology, Agile is a piece philosophy. It was developed within the 90s by software program engineers as a option to clear up the restrictions of present work strategies. Fairly than set up a particular option to do issues, Agile established a sequence of rules to enhance work.
The Agile Manifesto
Agile’s rules could be discovered within the Agile Manifesto. In brief, they are often summed up in:
- Individuals being extra essential than instruments or processes
- Software program that works needs to be prioritized over extreme documentation
- Collaboration with prospects as an alternative of negotiations
- Being resilient fairly than sticking to the plan
Agile Is Not a Methodology
It’s a widespread mistake to seek advice from Agile as one in all many work or course of administration methodologies. In sensible phrases, it’s a set of guiding rules for software program improvement, not a technique. In different phrases, Agile doesn’t state how one thing is to be carried out precisely. At Koombea, for instance, we use Agile rules for our app improvement tasks.
Agile’s rules usually are not unique to software-related tasks, though it’s notably good at it, particularly within the improvement part. Different disciplines have began making use of Agile rules, displaying nice outcomes. The important thing to implementing Agile efficiently lies in each group member adopting its rules. The stronger a group’s dedication is to Agile, the higher it really works.
Agile has given beginning to various frameworks which were adopted as software program improvement methodologies. Amongst these we discover:
- Disciplined Agile (DA)
- eXtreme Programming (XP)
- Function Pushed Growth (FDD)
- Lean Software program Growth (LSD)
Let’s check out Scrum.
The Scrum Methodology
Scrum is likely one of the varied frameworks that function below the Agile philosophy. It’s also known as a technique as a result of, opposite to Agile, it does have sure guidelines for a way a undertaking needs to be managed. These guidelines are also known as a sequence of greatest practices.
The principle high quality of the Scrum methodology is that it’s notably helpful to develop complicated adaptive tasks, that’s, these the place there are totally different brokers concerned, with totally different duties to be dealt with, in addition to numerous deadlines and phases of the undertaking, all interacting with each other in a non-linear manner. Due to this, it may be used for all kinds of product improvement tasks in addition to software program testing workouts. On the whole, one may even say that it’s excellent all through the event part.
Below Scrum, there’s one individual in command of managing the group. This individual is called the Scrum Grasp. The Scrum Grasp’s duty is to assist group members obtain their objectives. This contains:
- Serving to the Product Proprietor set up a product backlog
- Deciding on the work to carry out on a Dash in an effort to improve worth
- Inspecting outcomes and making ready for the subsequent Dash
- Ensuring the cycle could be accomplished and repeated another time
Crew members work in a self-organizing manner below Sprints, a interval of 1 to 4 weeks. All through this era, a undertaking backlog is organized in an effort to preserve observe of the actions being carried out in addition to these which can be carried out or pending.
