SRS ‐ Software Requirements Specifications
Created by IA SB JF AA FR
December 2023
This document is about the software requirements for “Dhar hobe”, a Bangladeshi Online Product Renting System, version 1.0. In our system, individuals have the option to both request the borrowing of categorized products for a specified period and lend out their own items. The system proves mutually beneficial for both parties, as the renter gains income while the rentee saves money by opting for temporary product use instead of purchasing it outright. The mission of this system is to help people and businesses make the most of their stuff, reduce environmental impact by shared consumption, and build a collaborative community that believes in access over ownership. This document aims to give a complete overview of what's needed for the entire product renting system. It outlines the features, performance expectations, limits, and connections necessary for developing, implementing, and maintaining the product renting software. More importantly, it covers the whole system and not just specific parts.
The Software Requirements Specification is designed to cater to a diverse audience involved in the development and utilization of the Product Renting System. The primary stakeholders include:
- Administrators: responsible for system management
- Business Analysts (BAs): tasked with understanding and defining business requirements
- Project Managers (PMs): overseeing the development process
- Developers: engaged in coding and implementation
- QA/QC Engineers: ensuring product quality
- End-users(Renters and Rentees): interacting with the rental platform.
- Marketing Staff: responsible for promoting the product renting system
- Testers: responsible for validating system functionality
- Potential investors: interested in gaining insights into the project's scope and requirements.
By tailoring information to each group's specific needs, the SRS aims to foster a shared understanding among the diverse stakeholders involved in the development and utilization of the Product Renting System.
The intended audience of our SRS has been declared in the previous section. In this section, we will discuss how they can use the SRS for better understanding.
- They will use the SRS to understand system requirements, deployment considerations, and potential administrative tasks associated with the Product Renting System.

- The SRS offers a comprehensive overview of the Product Renting System, helping investors make informed decisions about supporting the project.
The product renting system is like an online shop where people can share things they own with others. It lets you lend your stuff to someone who needs it for a while and also helps you find things to borrow without buying them.
This system is made to help people earn money by renting out things they don't use often. It also helps others find what they need without having to buy it outright.
- Helping People Make Money: It allows people to make some extra cash by sharing their things.
- Making Borrowing Easy: It makes it easy for people to find and borrow things they need for a short time.
- Building Trust: By letting people give reviews, it helps everyone trust each other more.
- Growing the Marketplace: By offering many different things to borrow, it makes the system more popular and helps everyone make more money.
- Keeping Up with Changes: It keeps up with the trend of using things temporarily instead of owning them.
This system fits our goals of trying new things, reaching more people, and making sure we give customers what they want. It's a way for us to grow our business by offering a helpful place for people to share things.
By creating this system, we're expanding how we do business. We're trying to make it easy for people to share and borrow things, which is becoming more and more common. This helps us be known for offering new and smart ways of sharing stuff.
The Software Requirement Specification of risk in potential that users (both renters and rentees) may not fully adhere to platform policies, terms of use, or ethical guidelines. This non-compliance could lead to issues reported to administrators, impacting the seamless experience intended for all participants and potentially compromising the overall integrity of the Product Renting System.
Risk that users (both renters and rentees) may not actively participate, potentially affecting the collaborative community-building aspect and the overall success of the platform.
Risk that administrators may face a high workload, especially in handling user issues and enforcing policies, potentially impacting the seamless experience for participants.
Risk that stakeholders may interpret the SRS differently, potentially leading to misalignment in project understanding and objectives.
