Table of Content

Project Development is a multiphase process in which every process is equally important. Here in this post, we are also going to develop our Online Chat Application Project in multiple phases, such as:



  1. Team Formation
  2. Topic Selection
  3. Creating Project Synopsys
  4. Requirement Gathering
  5. Coding or Implementation
  6. Testing
  7. Project Presentation

Let us look into the steps one by one.

Step 1- Team Formation Phase: Creating a Dynamic Team

Team formation for a final-year project is a crucial aspect that can significantly impact the success and efficiency of the project. In the final year, students often have diverse academic backgrounds, skills, and interests. Therefore, forming a well-balanced team becomes essential to leverage the strengths of each member and address any potential weaknesses.

In Our project as we will be exploring about web application for Online Chat Application so we will be required below skill sets.

  1. Front end Developer
  2. Back end Developer
  3. Tester

Step 2- Topic Selection

While making our project of Online Chat Application this will be our second step in which we will find an interesting problem statement and try to generate an idea to solve that problem using our knowledge.

Choose a topic related to your field of study that is of great interest to you. It is advised that you pick a topic that has a powerful motive. For instance, a project that helps humankind will truly be unmatched. Another factor to keep in mind is to choose topics that aren’t very common. 

Topic Planning: In this phase team will gather and try to search a topic or problem statement by brainstorming , reverse thinking or any other strategy and select a problem which is challenging in nature and solvable by using their combined knowledge of tech.

Defining & Set Objective: After planning the problem statement we will define clear problem statement and its objectives.

Result : In the end of this phase we will be having a problem statement for our project.

In our example we are selecting the topic ” Online Chat Application ” .

After the selection of the topic we are going to start our project work in the following steps:

Step 3- Project Synopsys for Online Chat Application

A project synopsis serves as a concise overview or summary of a proposed project, offering a brief but comprehensive insight into its objectives, scope, methodology, and expected outcomes. It typically acts as a preliminary document, providing supervisors, or evaluators with a quick understanding of the project before they delve into more detailed documentation.

The project synopsis usually includes key elements such as the project title, problem statement or context, objectives, scope and limitations, methodology or approach, expected outcomes, and the significance of the project in the broader context. It serves as a roadmap, guiding readers through the fundamental aspects of the project and helping them grasp its purpose and potential impact.
