🎯 Defining and Linking Business and Stakeholder Requirements

This paragraph delves into the specifics of business and stakeholder requirements. Business requirements are described as high-level statements of goals, objectives, and outcomes that initiate change, applicable to an enterprise level or a specific business area. Stakeholder requirements, on the other hand, are the needs of stakeholders that must be met to achieve the business requirements. The paragraph illustrates this with an example of monitoring vendor response times to reduce lead times. It underscores the interdependence of business and stakeholder requirements, where the latter supports the achievement of the former.

🔍 Exploring Business Rules and Solution Requirements

The paragraph discusses the role of business rules in shaping solution requirements. Business rules are the policies, calculations, authorizations, and constraints that guide and restrict the organization. These rules directly influence the development of solution requirements, which encompass the expected features and behaviors of a system or product. The paragraph differentiates between functional requirements, detailing the expected features of a system or product, and non-functional requirements, which relate to the system's behavior in its operating environment, such as security, usability, and performance.

🛠️ Transition Requirements and Business Analysis Techniques

This paragraph focuses on transition requirements, which are unique as they describe the capabilities and conditions necessary for shifting from the current state to the future state of a solution. These requirements are temporary in nature, with examples including user cheat sheets and data migration. The speaker also mentions various diagrams and techniques used in business analysis for capturing and understanding requirements, such as business process models, use case diagrams, and user personas. The paragraph concludes with a teaser for follow-up videos that will delve deeper into these business analysis tools.

Keywords

💡Business Analysis

Business Analysis refers to the process of evaluating a business situation and identifying solutions to improve or solve problems. In the context of the video, it is the primary focus of the BABOK, which provides a framework for systematic and structured approach to conducting business analysis. The main theme of the video revolves around the different types of requirements that are essential for effective business analysis.

💡BABOK

BABOK, which stands for Business Analysis Body of Knowledge, is a comprehensive guide that defines the profession of business analysis. It provides a detailed framework and set of standards for identifying, analyzing, and managing the requirements of change in an organization. The video uses BABOK as a reference point to explain the four main types of requirements and their subcategories.

💡Requirements

Requirements are the specific needs or conditions that must be met by a project or system to solve a business problem or achieve a business goal. In the video, the term 'requirements' is central to the discussion, as it outlines the different types of requirements that need to be identified and managed during the business analysis phase.

💡Business Requirements

Business Requirements are high-level statements of goals, objectives, or outcomes that explain why a change is needed in an organization. They provide the rationale for initiating a project or change and are essential for guiding the development of solution requirements. In the video, business requirements are depicted as the starting point for analysis, setting the stage for further breakdown into more specific requirements.

💡Stakeholder Requirements

Stakeholder Requirements describe the specific needs of the stakeholders that must be met in order to achieve the broader business requirements. They are more detailed and focus on the perspectives and interests of those who have a stake in the project or change. The video emphasizes that business requirements must support stakeholder requirements, ensuring that the solutions developed meet the needs of all involved parties.

💡Solution Requirements

Solution Requirements refer to the expected features and behaviors of a system or product that will meet the stakeholder requirements. They are derived from the business and stakeholder requirements and provide the necessary detail for the development and implementation of the solution. The video categorizes solution requirements into functional and non-functional requirements, which guide the design and development process.

💡Functional Requirements

Functional Requirements specify the actions or functions that a system or product must perform. They define what the solution should do in terms of features, capabilities, and behaviors. In the context of the video, functional requirements are a subset of solution requirements and are essential for outlining the expected performance and usability aspects of the final product or system.

💡Non-Functional Requirements

Non-Functional Requirements pertain to the attributes or qualities of a system or product, rather than its specific functions. They describe the conditions under which the system operates, including aspects like performance, security, and usability. These requirements ensure that the solution not only performs the necessary functions but also meets the quality standards set forth for its operation.

💡Transition Requirements

Transition Requirements describe the capabilities and conditions needed to facilitate the shift from the current state to the future state of a system or process. They are temporary in nature and support the change process during the interim period. Once the change is complete and users are accustomed to the new system, these requirements are no longer needed.

💡Business Rules

Business Rules are the policies, calculations, authorizations, limitations, triggers, or constraints that guide and constrain the operations of an organization. They directly influence the solution requirements by setting boundaries and guidelines within which the solution must operate. Understanding and incorporating business rules into the analysis is crucial for ensuring that the resulting solution aligns with the organization's policies and procedures.

hi everyone and welcome back to my

channel so in today's video I'm so

excited to share the 4 different types

of requirements as defined by AB a Bock

so for those of you who are unfamiliar

with Babic it actually stands for

business analysis body of knowledge so

basically it's a framework that you can

use in order for you to facilitate or to

help your understanding throughout

business analysis phase of an

implementation or a project so as you're

aware these requirements are typically

conducted at the beginning stage of a

project or an initiative so these

different types of requirements need to

be captured and documented throughout

your business analysis stage in order to

really ensure that you are actually

solving the problem that is stated by

the business or your customer so I'm

very excited to share today's video

because I have an awesome diagram that's

going to show the different types of

requirements and what they're used for

and some of the examples as well so I'm

not just going to talk about what those

four requirements are but I'm going to

also talk about what are some of the

real examples and how they're defined in

bad luck as well so if this is something

that you want to find out more and then

just keep on watching I mentioned before

there are four main different types of

requirements starting with business

requirements stakeholder requirements

solution requirements and transition

requirements however in this diagram

there's two more requirements and those

two requirements are called functional

requirements and non functional

requirements the reason why I didn't

mention these two requirements before is

because they are actually subcategories

under solution requirements so when we

talk about solution requirements we

actually talk about both functional and

non-functional requirements that make up

the solution requirements and as you can

see from the top we start off with

business requirements which is more at

the high level and then as we go down

towards the bottom where functional

non-functional and transition

requirements are these are very specific

requirements

so we start from top very high level and

then we work our way down so when we do

our analysis we normally start off with

business requirements and then we move

into stakeholder solution and then into

transition requirements so now let's

take a look at the diagram essentially

the definition of business requirements

is statement of goals objectives and

outcomes that describe why a change has

been initiated this can apply to a high

level enterprise or it could be a

specific business area or a project or

initiative basis business requirements

are typically high level business goals

and objectives as I mentioned before so

an example can be such as we would like

to automate our vendor management system

so that we can streamline end to end

process it so that the vendor lead time

is reduced by 50% in the next 12 months

so next next one is stakeholder

requirements as you can see business

requirements must support stakeholder

requirements and essentially stakeholder

requirements is describing the needs of

stakeholders that must be met in order

to achieve the business requirements for

example it can be such as we would like

to have a mechanism to monitor the

response time for each and every vendor

process on a daily basis in order to

reduce the lead time the report should

be generated daily monthly or on ad-hoc

basis in order to monitor this trend so

there can be various types of

stakeholder requirements but it is

important to remember that business

requirements must support stakeholder

requirements and stakeholder

requirements are achieved by business

requirements in this in this cycle okay

the next one we're gonna move on to

business rules so business rules are

policies that direct and constrain the

organization so it can include different

types of policies calculations

authorizations limitations any triggers

or constraints so these business rules

actually directly influence solution

requirements so when you're trying to

come up with solution requirements or

when you're brainstorming for ideas for

your solution requirements you have to

take business rules into account because

there might be some functional or

non-functional requirements that may

have to be tweaked a little bit or

change in order to accommodate business

rules so solution requirements refer to

the expected features and behavior of

the system or product

it describes the capabilities and

qualities of a solution that meets the

stakeholder requirements they provide

the appropriate level of detail to allow

for the development and implementation

of the solutions so as I mentioned

before there are two main types of

solution requirements which are

functional and non-functional so the

functional requirements are what's

expected features of the system or a

product so it could be things I stirring

a new user making a bid online using

vendor self-service and being able to

print various types of reports etc but

as you can see it could be a list of

anything because functional requirements

essentially refer to the question of

what must the solution do so if there is

any specific feature or enhancement that

you're looking for in this specific

product then you have to make sure to

capture them on the other hand

non-functional requirements are the

requirements which are related to the

behavior

the system so conditions of the

environment in which the solution must

operate so this includes privacy

compliance security and access

documentation usability and traceability

accessibility some of the examples could

be really page should load in five to

ten seconds or how often the information

is going to be saved when a new vendor

enrolls

or data security so any of these

requirements can be classified as

non-functional requirements under the

solution requirements last but not least

we have transition requirements so these

are unique in nature because they

describe the capabilities that the

solution must have and the conditions

the solutions must meet in order to

facilitate transition from the current

state to the future state so it's only

going to be available for the interim

period but once the change is complete

then it's no longer going to be needed

so it's very temporary in nature

examples are things like user cheat

sheet data migration from old system to

the new system so these are transitional

requirements that must be thought of or

prepared before we have or implement a

new process or a new change but once

users become familiar with the system

they no longer one day will gonna

require cheat sheets right because

they're going to be accustomed to the

new system and the same thing with data

migration once you move data migration

from an old system to the new system

then you're not going to require this

data migration because everyone's going

to adopt the new system and they're

going to input the data in the new

system so this is why these two examples

are good transition requirements so I

wanted to share this one page of diagram

with you

because these are some of the models or

diagrams that business analysts can use

in order to help throughout the process

of business analysis as well as

capturing requirements so once we gather

requirements we can often put them into

different diagrams in order to help us

with our understanding and confirm that

we have we have a pretty solid

understanding of what the requirements

are so under the solution scope I am

most familiar with business process

model and use kiss use case diagram so

I'm gonna in the follow-up meeting I'm

going to talk about a business process

model specifically because there are

just so many different aspects that I

want to include in the follow-up video

but I just wanted to give you a sense

that throughout this requirements phase

there are so many different types of

diagrams that you can utilize and things

like user personas user stories workflow

model wireframes reports non-functional

requirements functional requirements

these are all the techniques and

diagrams that you can utilize in order

to help you solidify your understanding

of the requirements in order to minimize

the gap between your understanding and

what the business expects in the future

so and so I'm not going to go into

details about what these diagrams or

techniques are in today's video I just

don't have enough time to go over

everything here but what I'm gonna do is

I'm gonna hand pick some of these

diagrams and then we're gonna do a deep

dive in the follow up videos so it for

today's video I hope you guys found it

useful if any and if you guys have any

specific questions please feel free to

comment below and and I'll talk to you

guys later bye
