💻 Introduction to SCRUM in Software Engineering

The speaker introduces the SCRUM model, a widely adopted software development framework, highlighting its origins from agile technology and the rugby sport. SCRUM is explained as a model applicable not only in IT but also in industries like research, sales, marketing, and banking. The model is lightweight, iterative, and incremental, making it popular among companies like Google, Facebook, and Amazon. The core concept of SCRUM is breaking down development into time-bound phases called 'sprints.' The analogy of sprints with short, high-effort races like those run by Ussain Bolt is used to emphasize the importance of maximum effort in a limited time.

⏳ SCRUM's Structure and Sprint Process

This section focuses on the sprint process in SCRUM, where development is broken into short, focused cycles lasting between two weeks and a month. Each sprint is reviewed, and stakeholders hold meetings to assess progress before moving on to the next phase. The process emphasizes constant communication and review with stakeholders, ensuring that all necessary changes are implemented in subsequent sprints. SCRUM teams are composed of developers, scrum masters, and product owners, with daily standup meetings fostering collaboration and transparency.

🤝 Collaboration and Flexibility in SCRUM

The speaker elaborates on the collaborative nature of SCRUM, emphasizing equality among team members. Unlike traditional hierarchical structures, SCRUM allows everyone to contribute ideas, fostering creativity and flexibility. The scrum master monitors the team's progress and facilitates communication with stakeholders and clients (referred to as product owners). This decentralized approach promotes quick adaptation to new ideas and ensures that teams can respond to changes effectively, ultimately reducing risk and improving the product quality.

⚡️ Advantages and Time Efficiency of SCRUM

SCRUM is presented as a method that reduces development time by up to 40%, with customer satisfaction being a key focus. The sprint structure ensures that work is delivered incrementally, and pending tasks are prioritized. After each sprint, a demonstration is conducted to showcase progress to clients, ensuring continuous feedback and satisfaction. This iterative process helps prevent mistakes from snowballing into larger issues by addressing them early in the development cycle.

👥 Challenges and Limitations of SCRUM

Although SCRUM is effective for small teams, the speaker points out that it may struggle in larger organizations where hierarchical structures exist, such as in universities. In larger teams, decision-making becomes more complex, making SCRUM less effective. Once a sprint is planned, no changes can be made until the next sprint review, which can limit flexibility during development. Despite these challenges, SCRUM remains a widely used and popular model across industries.

Keywords

SCRUM is a lightweight, iterative, and incremental software development model under the Agile methodology. It focuses on dividing development into small, manageable sprints. The script explains how SCRUM helps tackle complex projects by breaking them into cycles, much like the quick bursts of effort in a sprint race, enabling flexibility and quick progress.

💡Agile

Agile is a flexible project management framework that emphasizes adaptability, collaboration, and rapid delivery of software products. The video mentions Agile as a broader methodology that SCRUM falls under, highlighting how it supports continuous improvement and allows teams to adapt to changes quickly during development.

💡Sprints

A sprint is a time-boxed phase in SCRUM where a specific portion of the project is completed. Each sprint usually lasts between 2 weeks to 1 month. The video compares sprints to short, intense bursts of effort, like in sprint races, where maximum work is done in a limited time, enabling incremental development and reviews after each phase.

💡Backlog

In SCRUM, the backlog is a prioritized list of requirements and tasks that need to be completed during a project. It is discussed in the video as a place where stakeholders, developers, and clients collectively decide what features to implement. The backlog is a dynamic document updated regularly to reflect new priorities.

💡SCRUM Master

The SCRUM Master is responsible for ensuring the SCRUM process runs smoothly by facilitating communication between team members and stakeholders. The video explains how the SCRUM Master acts as a bridge, managing the team’s workflow and coordinating with clients and product owners to meet objectives.

💡Product Owner

The product owner represents the client or stakeholders in a SCRUM team, ensuring that the development aligns with the business requirements. The video mentions how this role is key to deciding what gets prioritized in the backlog and maintaining a constant dialogue with the team for the project's success.

Highlights

Introduction to the SCRUM Model in Software Engineering as part of Agile technology.

SCRUM is widely adopted across industries like software, research, sales, marketing, banking, and pharmaceuticals.

SCRUM is a lightweight, iterative, and incremental model, used by major companies like Google, Facebook, Amazon, and HSBC.

The term 'sprint' in SCRUM is derived from the concept of short bursts of effort, similar to a 100-meter sprint in athletics.

SCRUM breaks down development phases into 'sprints', each lasting between 2 weeks to 1 month, focusing on completing tasks within a limited time frame.

A key part of SCRUM is the daily meeting (daily scrum), where developers and stakeholders discuss the project’s progress.

In SCRUM, the team is considered equal, providing freedom to share ideas and allowing for faster adaptation of new solutions.

The SCRUM master facilitates the process, ensuring communication between the team, stakeholders, and clients (referred to as product owners).

Backlog in SCRUM refers to the list of requirements and designs that need to be addressed, created through meetings with stakeholders and developers.

One of the main advantages of SCRUM is reducing development time by up to 40%, due to its iterative sprint-based approach.

SCRUM prioritizes customer satisfaction by demonstrating progress at the end of each sprint and incorporating feedback into the next sprint.

One drawback of SCRUM is that it works better with smaller teams, as it avoids hierarchical structures and relies on close collaboration.

Once a sprint begins, no changes are allowed until the next sprint, ensuring focus on current tasks but potentially delaying necessary adjustments.

SCRUM emphasizes reviewing each sprint to identify any errors, preventing repeated mistakes in future sprints.

Despite its challenges, SCRUM is extremely popular due to its flexibility, adaptability, and ability to deliver high-quality products with lower risk.

Transcripts

Dear students welcome to gate smashers

In this video i am going to explain

SCRUM Model in Software Engineering

It is also one of the software development model.

This comes under agile technology.

I have already told you about agile

Its advantage disadvantage each and every thing.

You will get its link down in description box.

Even you will get its link in suggested videos.

Must read out that one time.

So that firstly you get to know about agile

After that various technologies that comes inside that.

Like SCRUM, Crystal, FDD, XP

Among these the most popular is.

That is your SCRUM model.

The idea of this SCRUM

is taken from the rugby game.

What happens in rugby?

One formation is created in such a way

The opponents, the teams

By doing their head down in such a way

They are in a position

So that we can take the ball

So that we can capture the ball.

By this way it is designed.

By one way the developers

The developers are in such a formation by doing their head down.

Kind of idea that we took from here

They are going to solve a complex formation

They are going to create a big project.

By one type this idea has been taken

but this is not only used by software or IT industries.

If we talk about SCRUM model.

Whether you talk about research, sales,

marking, banking, pharmaceutical.

Maximum companies are using this model.

From last 8-10 years

This is a widely used or adopted model.

Next if we talk

SCRUM is a lightweight, iterative and incremental model.

Here it is lightweight.

It is not a very complex model.

Iterative we are doing step by step

and it is incremental model.

Due to this many companies if we talk.

Google, Facebook, Amazon are using it.

Together with it HSBC Bank of America

The banking industry, sales, marketing

Those people are also using this somewhere.

What is the main idea in SCRUM?

SCRUM breakdown the

development phases into the stages or

cycles called "sprints".

This is very important line.

Sprint see sprint

Again from where this word is taken?

One is marathon

In which you have to run for 5-10km.

In that time is there but

you have to maintain the speed properly.

But if we talk about sprint

You have definitely listened about Ussain Bolt.

If we talk about Ussain Bolt

In that you have to run only 100m.

Easily everyone can run 100m.

but in that 100 metre

How much km force you have to apply?

You have to finish 100m in 9-10 seconds.

You know that in this much time

In this much second you have to ran 100m.

It means you have to apply maximum efforts in less time.

Same thing is here also.

Time is very important constraint here.

In limited time

There is time boundation

In that you have to provide work by finishing.

The development time for each sprint

is maximized and dedicated thereby by

managing only one sprint at a time.

Means one sprint is completed first

because it is iterative

One sprint is completed first.

Sprint is duration of time

and the one who are working in it.

We took general time of sprint

From 2 week to 1 month.

Your one sprint should be minimum of 2 week and maximum of 1 month.

When it is completed

After that reviewing that.

Seeing that by helding meeting with stake holders

This work is done

All the changes in review

Bringing that in next sprint

Then designing the next sprint.

In such a way development phases works.

If we talk inside this

Then SCRUM team has scrum master

and product owner with constant

communication on the daily basis.

So if we talk inside SCRUM

Then here firstly we talk about backlog.

What is backlog?

These are keywords.

In this keywords are very popular.

In case in competitive exams, foreign university exams

or in interviews if you are asked.

Then they will ask you about keywords.

Backlog by one way

Backlog by one way it is a place where

the basic requirements, designs are mentioned.

Whether you talk about clients, stake holders, developers

By creating a meeting

What to make? How to make?

That thing is designed in backlog.

After that daily scrum comes

Daily scrum is a 10-15 minutes meeting

on daily basis

With developers and stake holders

Discussing with them

Brother this thing is working.

Then developer discusses with its team

After that the work is implemented but

in this funda is not there.

In agile also i told in this that funda is not there.

A team leader is there

Rest are subordiantes

Those subordinates took work from team leader

and they are doing work.

It is not like that.

Yes team leader will be here but by

one way it is that much important in team

as rest all of the members.

By one way all peoples are equivalent.

Due to this freedom is here

Freedom is to speak, work and adaption is also here.

If i have any idea

I am working at low level but i have an idea

Then i can give that idea freely

It is possible it can implement fastly.

Then scrum master

You can say scrum master by one way the one

that is monitering or handeling all the things.

It is handling team also.

Together with it, it is communicating with stake holders.

It is also communicating with clients.

Here we say client as product owner also.

This is the basic story of your scrum model

Then if we talk about advantages.

As i told earlier here

Freedom and adaption is there.

There is idea of adapting new things.

Than creating a high quality and lower risk product is its main advantage.

Then if we talk

Reduce the development time upto 40%.

As i told sprint

Means firstly sprint came to you

You have to complete that work in 2 week.

After that you have to work on next sprint.

When you started working on next

Then you don't have to take anything from past.

Those things are already done.

In case if there is any pending scrum

Any pending work remained

Then on top priority we have to finish that work.

SCRUM customer satisfaction is important.

On daily basis their meetings are occuring

Scrum master is telling about things

and when one sprint is completed

Then demonstartion is done.

This thing is happened like this

We are creating this thing in such a way.

Here customer satisfaction is taken very much important.

Then reviewing the current sprint before moving to the next.

Firstly review

That changes that should be happen

Bring them in next so that

it should not occur if one mistake is done

Then by repeating in next it became a large mistake.

Ending that in first is necessary.

Then if we talk about disadvantages.

It is okay we discussed about all things

but this model is not easy to work on a big team.

It is easy to work on small team

because in big team somewhere

Head then subordinates inside head.

What is inside big universities?

First of all principle then differnet HOD

After HOD's different professors came

With professor associative professor then assistant professor

Somewhere hierarchy is created.

Here the work is not of hierarchy

Here all are equivalent

All stages are working by sitting at a certain place.

So that is easy to work on small teams.

Then no changes.

If one time sprint is created

Then you cannot made changes in that.

After reviewing that and then

You can bring those changes in next sprint.

One thing that is prepared then it wil remain somewhere.

You can say these advantages or disadvantages

but it is widely used.

SCRUM is so much popular.

Thankyou
