The document outlines the Program Development Life Cycle (PDLC), which is a structured approach to software development involving stages such as problem definition, planning, design, coding, testing, implementation, and maintenance. Each stage is critical for ensuring the successful creation of software that meets user needs and performs efficiently. By following this organized methodology, developers can effectively manage the complexities of programming projects.

3. What is PDLC?
Programmers do not sit down and start writing code right
away when trying to make a computer program. Instead, they
follow an organized plan or methodology, that breaks the
process into a series of tasks.
Program Development Life Cycle
a process that developers follow to create software. It's like a
roadmap that guides us from the initial idea to the finished
product, ensuring that we create effective and efficient
programs.

5. Program Development Life Cycle
The first step in the PDLC is to understand
the problem we want to solve. This involves:
Identifying the problem.
Understanding the requirements.
Defining what the program should do.
Program Definition

6. Program Development Life Cycle
Once we understand the problem, we move on to planning. In
this stage, we:
·Create a plan or roadmap for how we will develop the
program.
·Determine the resources needed, such as time, money, and
tools.
·Outline the tasks that need to be completed and set
deadlines.
Planning helps us stay organized and ensures that we have a
clear direction.

7. Program Development Life Cycle
Next, we design the program. This involves:
·Creating algorithms and flowcharts to outline the logic of
the program.
·Designing the user interface, deciding how the program will
look and feel.
·Ensuring that the design meets all the requirements
identified in the problem definition stage.
Think of this stage as creating a blueprint for our program.
3. Design

8. Program Development Life Cycle
With the design in hand, we move on to coding. In this stage:
·Developers write the actual code using a programming
language.
·They follow the design and algorithms created in the
previous stage.
·This is where the program starts to take shape.
Coding is like building the house from the blueprint we created.

9. Program Development Life Cycle
After coding, we need to test the program to make sure it
works correctly. This involves:
·Running the program to find and fix any bugs or errors.
·Ensuring that it meets all the requirements and works
under various conditions.
·Performing different types of testing, such as unit testing,
integration testing, and user acceptance testing.
Testing ensures that our program is reliable and does what it's
supposed to do.
5. Testing

10. Program Development Life Cycle
Once testing is complete and we're satisfied with the
program, we implement it. This involves:
·Deploying the program to the environment where it will be
used.
·Training users on how to use the program.
·Making the program available to its intended users.
Implementation is like moving into a new house after it's built
and ready.
6. Implementation

11. Program Development Life Cycle
The final stage is maintenance. After the program is
implemented, we need to:
·Monitor its performance and make any necessary updates
or improvements.
·Fix any issues that arise over time.
·Add new features or make changes based on user
feedback.
Maintenance ensures that our program continues to function
well and meets users' needs over time.
