The 8-Point Guide to Make an Excellent Proposal Document

If you want to make an incredible mark with your proposal document, here are the eight things you should include.

1. A Detailed Description of the Idea

The first thing you should include in your app idea proposal is the idea itself. Talk about the concept. Introduce the idea to the readers and tell them what you are planning with the idea. 

At this point, you need to identify:

  • The pain points that your app idea would solve
  • Talk about the issues you considered when drawing the application concept
  • How you validated the idea and checked the target niche?

When discussing the app idea, you should tell the website or mobile app development partner how it fits your business and its goals. Talk about how you believe the app will help the end users. What is the background behind this idea? A detailed concept outline with validation reports can help the developer understand what you want. You can also attach interviews with key stakeholders about the need for such an app.

For example, when you connect with the sales team, they will tell you what the users need and the gaps in the existing apps. This will help formulate the idea or become the foundation for your concept.

2. The User’s App Usage- navigation, learning curve

When you write the proposal document, you should back it up with appropriate high level research. The user's usage is among the many things that make sense to your development partner. This will help build the experience for the mobile app and plan the interface. 

While outlining the concept, you would have defined the target audience for your application. It is time to understand how these users use the mobile app. Do they hold the application with one hand, or do they use it in a cradled form? Do they hold the phone in one hand and operate it with the other? 

These are things that you should consider when planning the mobile app experience. You should conduct secondary research or a focussed group interview to understand their usage. The existing learning curve can also help you understand their usage. You can check what type of apps they use and what navigation is proposed in these app solutions to gain further knowledge. 

3. Mention Apps in the Niche

The app idea proposal document should comprise the names and screens of the competition apps. For example, when creating an idea document for an on-demand laundry app, you should mention the apps in this niche.

You can mention how many apps exist in your location versus globally. Talk about these apps in detail- what they do and how they help the users. You can also showcase the screens of these apps for better understanding. 

Tell the app development company why these apps have been used as examples. Show them apps that you believe have an interesting combination of interface and experience design.

4. Must-have Features for Better Usability

If you are working on a mobile application to make it usable, you should think through the features. For example, in the case of an eCommerce mobile app, you should have a smooth checkout process. Similarly, when creating a healthcare app, you should incorporate HIPAA compliance. These things can help you create a more usable app.

The mobile app idea proposal document should include all the features that you believe will improve the overall app usability. It should be a well-thought-out and researched document. Make sure to add the features that you think are relevant. 

Note: The features can be brainstormed later with your development company and refined according to the latest trends and some terms and conditions.

5. Functional Aspects

When you are writing the document, you should mention your solution's functional requirements. For example, how you want the user to input certain details and how the queries will be generated are part of the functional requirements.

At the same time, you should also consider the non-functional requirement that includes the application's security, compliance and performance. Make sure to detail all the requirements so that the mobile app development partner will understand your requirements thoroughly. 

It is equally important to have small snippets that help understand what you mean to convey. For instance, in the case of security, you should tell them what you expect. How will two-factor authentication work?

Answering the basic questions can help the developer visualize the app and its coding better.

6. Share User Stories

An app will function for multiple scenarios. For example, the Asana app can be used for collaboration and projection mapping. It can also be used to plan your entire month. These are things that a user can do with this productivity app solution. 

Now, if your app is used for multiple scenarios by many users, you need to create the scenarios for these users. User stories will comprise these scenarios in detail and offer a better view of the app's vision.

You will talk about how the user will enter the app, use the app and engage with the app. each user story will have a navigation and usage story associated with it.

7. Suggested Wireframes

If you have been sketching or are someone who understands design, you can create wireframes to support your idea. You can even use the no-code tools to create a prototype of the app idea to help the developer understand what you are proposing. 

While this step is not mandatory, it can improve the ability of the development company to prepare the base for your mobile app development project. They will know what you are looking for, and how you aim to offer the application to the end users. A visual story speaks volumes.

8. Dependencies for App Development

This is an essential component that suggests the success of your proposal document. You will discuss the assumptions and dependencies that will make the mobile app project a hit. For example, you will tell the developer your possible assumptions for the application. 

Say, you are using a third-party API you assume that it is not vulnerable. Similarly, you will mention the dependencies on the third-party tools and libraries to build the mobile app solution. 

Note: You might have considered the third-party libraries or tools based on your research and features included in the application. 

Now that you know the components to create a mobile app idea proposal, here’s the step-by-step guide to building the document.
