How to Write a Software Development Project Plan

A software development plan describes the development process step by step — It covers planning, ideation, development, documentation, deployment, launch, and sometimes maintenance

What’s a software development plan?

Software development project plans allow product owners, stakeholders, and developers to optimize development. The goal of a software development plan is to provide clear answers to the following questions:

  • Which functionality is chosen to solve this problem?
  • Which tasks need to be formed to develop the described functionality?
  • What is the order of the feature development?
  • Who is involved in the project?
  • How is responsibility divided among the team members?
  • What are the expected dependencies in the product?
  • What quality metrics will define the efficiency of the project and the quality of the product?

If there’s a conflict or a team bumped into a dead end, they should be able to come back to the development plan and find the solution to their concerns. Preventing miscommunication and organizing the process is the main SDP meaning.

How to create a software development plan

To write a software development plan, you need to get all participants of the project on the same page. You can organize remote meetings via Zoom or Skype to discuss the plan’s structure and the main points.

After the whole team discusses preferences regarding the plan’s contents, assign a responsible manager who will take responsibility for the plan’s completion. Usually, at this stage, business analysts and project managers carry the most responsibility for the document.

The structure of the software development project plan

The first step in writing a software development plan is establishing its key components. In this part, we will examine the sections of a typical software development plan, and give you a checklist about their contents with a sample of a software development project plans.

Introduction

This section describes the purpose of the software development project and product. Your goal is to define which type of development the document describes, finalize the product’s overall concept, and your team’s main expectations.

  • The project description: product concept, goals for the development;
  • The project needs: this section refers to business and functionality objectives;
  • Abbreviations: you need to describe all the acronyms, special symbols, and certain forms, used in the document.

Project organization

A software development plan should depict the team’s structure, assign the managers of the project, and their responsibilities. You can create a table with all project participants and describe their functions in detail — here’s an excerpt from a software development planning template.

In this section, the team should describe any involved external groups — other teams and experts that developers will interact with. Typically, a software development project involves the following groups:

  • Testing/QA. If testers don’t cooperate with developers at the beginning stages or participate actively in ideation and research, it’s better to refer to them as an external group rather than all-time participants.
  • Deployment. A software development plan should give detailed information on where operation teams come in and what their responsibilities are. It should also describe how developers and deployment specialists interact in their respective areas of expertise.
  • Marketing: marketing specialists have to join a software development project at the initial and final development stages for sure. A plan should assign a go-to marketing expert, whom developers can contact at any point in the project.

The project organization section allows teams to increase transparency. All participants know who works on the project and are aware of everybody’s responsibility. If there’s a bottleneck, you’ll have no issues with tracing the responsible team member.

Management

This section of a software development plan describes the stages of the software development project, estimates the workload, and provides estimates.

  • Estimates: predicted duration and cost of the project should be backed up with the team’s reasoning and circumstances for potential re-estimation.
  • Project plan: here, the plan states an approximate schedule, the project’s main stages, and available resources.
  • Development phases: a project plan provides only a general description of the development process. You can go into more detail when describing each phase individually. For every phase, a team specifies its duration, objectives, and required resources.
  • Objectives: each phase and product iteration should be driven by clear goals. Make the list of objectives for every stage of product development. The product owner and the development team should keep these objectives realistic and clear to all project participants.
  • Release plans: the team can give an estimate on the expected release date and specify its status (beta-, demo, alpha, etc.)
  • Resourcing: this section describes available and unavailable skills, hardware, and software. For each stage, there should be individual resourcing sections.

The management section of a software development plan should be constantly revisited throughout the project. The team’s estimates, resources, and deliverables will likely change, and software development plans should reflect these shifts. However, it’s crucial to keep the first version of the document intact, so stakeholders can always point at initially planned objectives.

Project control

This section describes actions and approaches that the team and stakeholders will take to oversee the quality of the project and the team’s efficiency. It’s important to define your metrics beforehand, so all members know what they agree to. Here’s a checklist for planning project monitoring — and a software development plan example.

  • Compliance with requirements: the software development team should offer strategies and tools that will be used to control the correspondence of the product to requirements. This includes user, business, functional, non-functional, and other software development requirements.
  • Budget and schedule monitoring: you need to set up time and budget constraints. If there’s a threshold that the team should be aware of, it’s best to notify everyone at the beginning of the project. Describe which tools you will use to ensure cost-efficient resource allocation.
  • Quality assurance: most development teams have their own tech stacks when it comes to code quality control. They should specify which tools they will use and provide the product owner with real-time access to all the reports.
  • Management: the project manager should have a set strategy for updating stakeholders on the team’s methodology, cooperation approaches, and communication methods.
  • Risk prevention: the team should describe which tools and methodologies were used to evaluate the project risks.
  • Finalization: a software development plan should include a clear definition of done — a set of conditions that a product or feature should meet to be seen as complete.
  • Problem-solving: the management section should offer step-by-step algorithms for resolving conflicting situations. The team should offer a list of tools, deliverables, metrics, and mediators — all people and tools that will be involved in resolving an issue.
  • Improvement plan: the team should describe when they are revisiting strategies established in the plan and which improvements they will be focused on throughout the project.

Maintenance and support

After the development process is finalized, the cooperation between developers and the product owner rarely ends. Technical assistance will likely be required throughout the entire lifecycle of the product. A trustworthy software development partner understands this and documents this process in a software development plan — long before starting the project.

Having a detailed plan on maintenance, support, and documentation practices allows product owners to avoid vendor lock-in. The software development team should describe which information and assistance they will provide to the owner.

  • Testing: if a team handles QA and testing as well, ask them to provide a separate plan;
  • Tech debt: developers should be held accountable for technical issues, found in their code. A development provider has to describe ways of handling tech debt and code quality control.
  • Documentation: the development team guarantees to deliver particular documentation (including a full list with all the documents).
  • Maintenance and future releases: a software development plan can include the description of post-release cooperation between the product owner and the vendor.

Setting up a clear algorithm for further support of the project ensures its long-term viability and scalability.

Risks associated with software development planning

Obviously, things can go wrong as early as at the planning stage. Some aspects of development can’t be objectively defined before the team actually starts working on the project, whereas others require experience. If you’ve never written a software development plan, take a look at these most common software development risks. In our experience, these are the issues that typically sabotage planning — but the good news is that most of them can be avoided.

First estimates are highly approximate

A software development team should emphasize that there’s no 100% certainty in cost and time estimates. If a vendor promises to deliver everything at some definite time and on a budget, chances are, these experts lack experience in planning. A trustworthy team always takes margins of error into account.

The bigger the scope, the higher the risks

The size of the project is another crucial aspect that influences the success of a plan. When a team is preparing documentation for large-scale projects, they only see a bird-eye view of the project. The more stages there are in the project, the more bottlenecks can occur. A dead-end on one development phase will cause a delay in another one. It’s a natural process that needs to be taken into account.

Plans can tackle wrong needs

A software development plan has to be revisited all the time. When developers and business analysts create software development plans, they still lack a full understanding of project specifics. During the projects, the team’s and owner’s vision of the project can change dramatically. It’s necessary to rewrite a software development plan and make sure it always suits the latest project needs.

Plans do not correlate with users’ best interests

Make sure never to skip user research and direct communication. Defining your target audience and talking to potential clients is the key stage of successful software development planning. If the project’s scope and requirements didn’t undergo user validation, you risk developing an irrelevant solution.

All teams aren’t on the same page

If a software development team cooperates with external teams, they should also be included in the process of software development planning. Ideally, the goal is to organize a meeting where all members, internal and external, are present. Having at least 1–2 common calls will help you keep everyone in the loop and understand their vision of product development. Getting everyone up to the same speed early on will help avoid conflicts and miscommunications at the later stages.

Best practices for creating a software development plan

To succeed in software development planning, you just need to follow standard best practices. They are very feasible — you won’t need much time to incorporate them into your cooperation, but in the end, these details will make a difference.

The work is broken down into modules

Creating the entire plan in one sitting is an impossible mission. You will need to break the process down into manageable chunks. We suggest using a module system: define each section as a module and assign responsible team members. Set a deadline for each module and make sure that all teams are transparent about their work scope.

Research is shared real-time

Research is an indispensable process during software development planning. The results of market research, user reviews, interviews with focus groups, and analysis of similar projects should be available to all team members in real-time. If there are updates, all members must receive them simultaneously.

The plan is constantly revisited and modified

Software development planning is an ongoing process. The scope of priorities of software development is constantly evolving. Software development has to be relevant, which is why the team needs to revisit it on a regular basis. Be sure to keep the previous versions as well, just in case there’s a dispute during the project. You can use color codes to keep track of different versions — take a look at software development plan examples.

The team asks for users’ opinions

After the feature has been defined as done, a team has to test it on actual users. The findings should be reflected in a software development plan. Interactions with users might inspire the team to shift focus from one developmental approach to another or highlight a need to acquire new resources. All these changes have to be documented in the plan.

Conclusion

Software development planning is just as impactful as the development itself. It sets a foundation for your product’s success and provides the team with an opportunity to introduce stakeholders to their methods, methodologies, and standards. It’s a long-term investment: a software development plan will be one of your main documents for years. You can even reuse approaches in other projects and for other products.
