UNIT 1: INTRODUCTION
Executive Summary
This BRD is intended for Insperity to review the implementation of Machine Learning into the hiring
quoting software. This will be used to identify a trendline on backgrounds, gender, and race from various
departments to enable ethical hiring decisions and allow senior leadership a bi-weekly generated report
that can be used to follow up with applicants who’re less likely to apply right away.
Purpose of this Document
Review the current online hiring systems and take the data from historical advertisements and hires to
implement a machine learning algorithm for identifying applicants less likely to apply to the ad that was
broadcasted. With this data, we enable our hiring team to rapidly pursue these candidates to assist them
with getting a position that will work for them. We will be utilizing the SDLC Waterfall Model to work
through the design of this algorithm to implement.
Business Objectives
▪
▪
▪
Objective #1 – Take the historical online advertisement market data to generate trends analysis
for the last 10 years
Objective #2 – Take the trend analysis and create a machine learning algorithm to implement into
bi-weekly reports to hiring teams.
Objective #3 – Design a SOP for following up on applicants that did not apply for advertised
positions.
Project Objectives
▪
Implement Machine Learning data analytics to review the historical data of ads and hires.
Enabling our hiring team to rapidly pursue these less likely-to-apply candidates to assist them with
getting a position based off of historic data.
Potential Challenges
▪
▪
Lack of historical hiring trends.
advertisements that were started but not finished so we did not capture all the needed data to run
against the machine learning algorithm

UNIT 2: SOFTWARE DEVELOPMENT
METHODOLOGY
For implementation of a hiring software project, we selected the waterfall methodology. The waterfall
methodogoloy will break the project into a sequence of tasks to complete. The phases will be completed
in a waterfall approach and will require a stakeholder to sign off on each phase before the next phase will
begin. Please see below for the phases:
Analysis
Requirement
Specification
Design
Development
Testing &
Integration
Implementation/
Deployment
(Farley, C., 2023)
The waterfall method is based on three main principles: low customer involvement, strong documentation,
and sequential structure (Sergeev, A., 2021).
•
Customer involvement is kept low, which is preferred to keep them in the day-to-day tasks. The
team will meet with the developers to review what they want from the software and how they
want it to perform. We would then bring the customer into the testing phase to show what was
developed and how it works. At this time, if no changes are requested, then the final meeting will
be when it is ready to deploy
•
Documentation throughout the project is high. All steps are fully documented, and each
stakeholder with have signed off before moving to the next phase.
•
The sequential stages are the main fundamental principle of the waterfall method. It keeps the
project straightforward.
With the waterfall method, we can complete the project on time and with minimal stakeholder change
requests. Having the sign-offs at the end of each phase as well as the critical panels at the beginning to
gather the information from the client, and right after the testing, we can make sure this is what the client
wants, and we can roll out on time

UNIT 3: BUSINESS REQUIREMENTS
Functional Requirements List
Below are the functions that the developers will implement into the software for the Insperity
hiring software.
Req. Requirement
ID #
1.
Hire & non-hire reports are generated every 72 hours
2.
The hiring system will allow the hiring team to record candidates’ applications upon
follow up.
3
API interface to the hiring system
4
The system will allow candidates to revisit their applications using their phone number
or email address
5
The system will allow the candidates to submit feedback through a contact form in the
app
Non-Functional Requirements List
These functions will not affect the software’s functionality but how it will perform in day-to-day
use.
Usability
With appropriate training, the hiring teams can use the software and easily navigate the tasks
they must complete. The software must be functioning for the customers to navigate the hiring
easily.
Reliability
Every unsuccessful attempt by a user to access an item of data shall be recorded on an audit
trail. We can check the percentage of the probability of failure, or failure rate, to determine the
reliability of a system. If the ratio is higher, the system will likely function normally after important
use.
Performance
The website’s load time should be one second for customers at maximum. The software must
function with a response time of 5 seconds for the customers to navigate through the hiring with
ease.
Security & access controls
Users must change the initially assigned login password immediately after the first successful
login. Moreover, the initial should never be reused. Setting up security questions in the instance
that a user forgets their password is used to identify the user in the system to send a
temporary password.

Supportability
Updates to the system must be processed overnight to eliminate downtime for users. Software
developers must maintain the components after deployment for updates and upgrades.
Maintaining a data backup that is run every night so be able to recover quickly if the site were to
go down to eliminate data loss
Business Process Diagram
Insperity’s hiring application documents the process that follows up on unfilled billets completed
by external applicants in our online hiring system. Below is the process diagram to kick off the
project for Insperity. This process will be followed with the project management team to
determine if the project will be accepted to move forward, and if it does, what will happen to get
it started.
Project Timeline
The project timeline is detailed below; we can complete the development in 3 months using the
waterfall approach. It maps out what must be completed before a new task can commence and
keeps everything moving. Please see the next page for the project timeline.

UNIT 4: USE CASE DIAGRAM
SUMMARY USE CASE NARRATIVE
The use case model for the recruiting process scenario includes several important characters and
their interactions. The primary actors are the job seeker, the web platform, the hiring department,
the employer, and the business. Every player in the employment process carries out particular
tasks to play their part. The job seeker accessing the web platform starts the hiring process,
which acts as a focal point for available positions. The use case for the job seeker comprises
tasks like looking for job postings, sending an application, and checking the status of an
application. As an additional actor, the online platform offers a variety of use cases to assist job
seekers. These comprise showing job advertisements, enabling job seekers to apply, and sending
alerts or updates on the application’s progress. The recruitment unit is the major player
overseeing the recruiting process. Some of its use cases are receiving and examining
applications, creating a short list of prospects, holding interviews, and making the final decision.
Through the online platform, the employer, who represents the recruiting firm, communicates
with the system. Some of their use cases are accessing applicant profiles, analyzing applications
and cover letters, setting up interviews, and extending job offers. The firm participates in cases
involving formalizing the employment process as the last actor. Ensuring a successful integration
into the business involves negotiating and signing employment contracts, welcoming new hires,
and giving them the necessary tools. The recruiting process uses a case model that considers
various actors’ behaviors. In order to look for jobs and submit applications, the job seeker uses
the online platform. While the company evaluates applicants and makes job offers, the recruiting
section oversees the screening and selection process. Finally, the business formalizes the hiring
procedure by creating employment

UNIT 4: SEQUENCE DIAGRAM
SUMMARY SEQUENCE DIAGRAM NARRATIVE
The job seeker, the online platform, the recruiting unit, the employer, and the firm are five
important players who interact during the hiring process. The job seeker begins the hiring
process by visiting the online platform, which provides a doorway to available positions. The
web-based portal shows job openings and enables job seekers to submit applications.
The recruitment unit receives the application after it has been submitted. Based on the credentials
and job requirements, this section is responsible for screening and shortlisting candidates. The
hiring department assesses each application and chooses a pool of prospects for further
consideration. The employer evaluates the shortlisted candidates on behalf of the employing
organization. They may visit the online platform to see the candidates’ resumes, cover letters,
and other pertinent papers. The organization assesses applicants’ eligibility for the post based on
their training, experience, and skills. The employer chooses the most qualified candidate, who
subsequently extends an employment offer. The candidate receives the offer and can accept or
reject it. The process advances to the following phase if the applicant accepts. An employment
contract is signed between the employer and the candidate, formalizing the hiring procedure. The
candidate joins the business as an employee and starts their tenure there. The applicant submits
their application over an online platform throughout the recruiting process. The recruiting unit
screens and shortlists individuals while the company evaluates the selected prospects and issues
an offer. The chosen applicant then signs an employment contract with the business and starts
working there. This series of encounters guarantees a methodical and regulated recruiting
procedure, helping businesses to discover the most qualified applicants for their vacancies.
