Software Development Plan: Comprehensive Guide and Free Templates

Behind every on-time, on-budget, and seamless software lies a solid and comprehensive software development plan. It’s the strategic roadmap that aligns resources, budget, and timelines, preventing potential project risks and assuring a smooth journey from concept to execution.

In this article, we will help you create a software development plan from scratch, by digging into fundamental knowledge, step-by-step guide, and best practices, and providing a popular software development plan template. Let’s get cracking!

What Is a Software Development Plan?

A software development plan (SDP)  is a strategic roadmap that outlines the entire software development life cycle (SDLC), including goals, resources, budget, and timeline. It helps ensure efficient development, resource management, risk prevention, cost control, and successful software delivery.

A well-crafted project plan for software development sets the foundation for a smooth software development project and acts as a bridge between development teams and stakeholders, ensuring everyone is on the same page. In contrast, a development project without guidance can lead to delays, budget overruns, and potential chaos.

A comprehensive software development life cycle project plan includes the following key elements:

• Project goals and requirements: Clearly identify the purpose, target users, functional and non-functional requirements, and desired outcomes of the end product.
• Timeline and milestones: Create a realistic software development timeline with detailed and precise milestones, providing a project roadmap for everyone to stay on track.
• Roles and responsibilities allocation: Define each team member’s responsibilities and tasks to guarantee efficient accountability and collaboration.
• Budget: Estimate the development costs, resources expenses, and other associated expenses.

 

How to Create a Software Development Plan: Step-by-step Guide

How to plan a software development project? Here are some key phases included in creating a software development plan:

Analyze the project’s scope and requirement 

Start your software implementation project plan by analyzing the requirements requested by the client. Here are some crucial factors to consider:

• Alignment: How does the client’s need and request fit in with the company’s ability and expertise?
• Resources: Does the company have the infrastructure, human, tech stacks, and time to achieve the project’s goals?
• Budget: What is the client’s offered pricing model and budget for this software development project? And is it consistent with the company’s pricing models and resources?

 

Define project objectives

After deeply understanding the client’s requirements for the project, the next step is identifying the software project’s goals and objectives. A clear objective provides a clear view of the roadmap and the final destination for the team. 

A well-defined objective and requirement right from the start is essential in a successful software development plan. It is the foundational “compass” to avoid misunderstandings, ensuring everyone understands the project’s purpose.

The project’s objectives defining phase includes specifying intentions, visions, and preferred endpoint. Applying formulas like SMART criteria (Specific, Measurable, Achievable, Relevant, Time-bound) can make objectives more concrete and actionable.

 

Build an effective software development team

Based on the objectives defined in Step 2, you can form a development team with roles and capabilities that match the project’s scope and meet customer expectations.

This step is critical, especially in a Waterfall or Scrum project. Picking the proper member right from the start decides the project’s success in meeting the quality and delivery time.

When it comes to agile software development projects, the team will be divided into smaller independent units. Each sub-team has its focus on distinct development phases.

In other scenarios, the project might need an outsourced team for certain tasks. Therefore, identifying involved stakeholders is also crucial in this step. In case your team has never cooperated with an external team before, here comes a list of 10 reliable agile offshore software development companies that are worth considering.

Lastly, after the full team is formed, assigning a project manager becomes essential for efficiently managing the entire team. The ideal project manager should possess prior experience in a similar or relevant project type, and have an in-depth knowledge of the domain.

 

Identify risks and mitigation

Now, when the clients, developers, stakeholders, and other parties are involved, the whole team can sit down together and identify potential challenges and develop a mitigation plan accordingly. 

To create a thorough plan, the team needs to go through end-to-end production stages, covering from development, testing, UI/UX design, and system integration to product launch.

In order to effectively manage risk, your team can leverage popular tools that help spot all possible issues like the risk matrix, also known as a probability and severity risk matrix. This allows demonstrate the probability of a problem occurring and predict its consequences. In case you are delegating your software development project to an outsourced team, make sure they are qualified with risk management certifications. 

LTS Group is an ISO 9001:2015 certified company which ensures that all of our project managers and technical leaders are fully aware of risk management and how to mitigate and eliminate risk throughout the software development process.

Create a timeline

Developing a software development project timeline with realistic deadlines, and milestones helps in setting expectations, and monitoring and tracking the progress. 

Milestones included in the development process could be “design phase complete”, “MVP version complete”, etc. These milestones determine tentative deadlines that allow clients, stakeholders, and internal teams to seamlessly keep track of the software delivery timeline. 

Before finalizing the timeline, make sure to have all the team member’s agreement. Any suggestions from the team members about extending deadlines, or any other arising tools, etc., should be discussed and agreed upon starting the project. This ensures no unexpected incidents will interrupt the software development process.

 

Continually review and adjust the project plan

In this ever-evolving technology industry, being flexible and adaptive is crucial to stay ahead of the game. Linear as the software development plan may seem, the project manager or team leader can collect project data and analyze it to make adjustments to the plan if needed to enhance efficiency.

This step requires a metric to track and evaluate the project’s performance and quality. Without these metrics and measurements, there won’t be useful data to analyze to make informed decisions and manage the project effectively.

 

Software Development Plan Templates

A project plan template for software development is a valuable “assistant” for an effective software project management plan and organization. It benefits your team in specifying requirements, organizing key details, and streamlining tasks by providing a standard outline. 

A well-designed software development plan template will help your team focus on the informed decision-making process, and the specialized work, by covering the following functions:

• Creating and updating project timeline, schedule, and status
• Tracking key performance indicators
• Determining priority for certain solutions and tasks
• Assessing the overall roadmap, project scope, and requirements
• Effectively addressing the process, technology requirements, and documentation across multiple teams

 

So, what makes a good software development template? Despite differing in specific functions, all the great software development plan templates share the following common characteristics:

• Ease of implementation: These templates should allow quick and straightforward setup, allowing seamless integration with other project management platforms and tools.
• Ease of update and customization: These templates need to be dynamic, quickly adaptive, updated, and customized as project progress changes, especially in agile projects.
• Visual focus: Templates with a user-friendly visual will facilitate collaboration among team members by providing a quick and easily understandable overview of important touchpoints.
• Ease of accessibility for stakeholders: All of your in-house and outsourced team members, and other inside-out stakeholders should easily access the templates system, ensuring smooth collaboration and communication regarding all project elements.
• Goal-centric accomplishment: Each template should focus on one core objective, whether it’s technology scope planning, mitigation plan, or project prioritization, ensuring that the template’s function can achieve its intended goal.
