After that, as you start to have some idea of how to go about your project, do the following:. Doing all of this before you even start writing your design doc lets you get feedback as soon as possible, before you invest more time and get attached to any specific solution. Often, even if the implementation stays the same, your reviewer is able to point out corner cases you need to cover, indicate any potential areas of confusion, and anticipate difficulties you might encounter later on.
This creates additional incentive and accountability for the reviewer. On that note, consider adding specialized reviewers such as SREs and security engineers for specific aspects of the design. Once you and the reviewer s sign off, feel free to send the design doc to your team for additional feedback and knowledge sharing. I suggest time-bounding this feedback gathering process to about 1 week to avoid extended delays. Commit to addressing all questions and comments people leave within that week.
Then, set up a meeting with the different parties to talk about these disagreements in person. Whenever a discussion thread is more than 5 comments long, moving to an in-person discussion tends to be far more efficient. In talking to Shrey Banga recently about this, I learned that Quip has a similar process, except in addition to having an experienced engineer or tech lead on your team as a reviewer, they also suggest having an engineer on a different team review the doc. For extra brownie points, treat this design doc as a living document as you implement the design.
Update the doc every time you learn something that leads to you making changes to the original solution or update your scoping. How do we evaluate the success of a design doc? My coworker Kent Rakip has a good answer to this: A design doc is successful if the right ROI of work is done. That means a successful design doc might actually lead to an outcome like this:.
At the beginning of this article, we said the goal of a design doc is to make sure the right work gets done. Seems like a pretty successful outcome to me.
Please leave a comment below if you have any questions or feedback! Giving credit where credit is due, I learned a lot of the above by working alongside some incredible engineers at Plaid we are hiring! Come design and build some sweet technical systems with us and Quora. If you like this post, follow me on Twitter for more posts on engineering, processes, and backend systems.

Most requirements documents will include a list of general product features as well as the detailed system behavior needed to deliver these features. Detailed system behavior is often expressed with use cases or usage scenarios.
Example of Software Design Document(SDD)
Project planning is the process of defining the expected outcomes of the project and devising a course of action for accomplishing them. The project plan documents the results of the planning process. Expect the project plan to be updated and refined continuously throughout the project as conditions change and more is known about the project. Few projects start with all the information needed to plan the project in detail from the beginning. More often, the project plan starts with a high-level breakdown of known work, a course grain schedule and only ballpark estimates for cost and duration.
Over time as more is understood about the project, these and other components of the project plan are progressively refined. The release plan is a high-level schedule that stretches for the duration of the project. There is one per project and it specifies the timing of iterations and a rough allocation of product features to iterations.
An iteration plan defines the activities that will be performed during an iteration. There is one per iteration and they specify the detailed tasks for an iteration, and in some cases an assignment of tasks to individuals. A memo of understanding is a less formal way of documenting assumptions and intentions. Verbal agreements are often documented in a memo of understanding.
Project success criteria describes how the results of the project will be measured. If the project is scheduled to be complete on July 1, will it be considered a failure if it is finished on July 2nd?
We provide these planning services with our projects, and offer them separately if you already have a design and development partner. The client should sign-off on the definition documents in order to begin the next phases of the website project. The Definition documents set expectations on both the client and agency-side as to the final website deliverables. The standard template lays this out as a series of boxes linked by directional arrows that illustrate relationship and hierarchy.

A sitemap can provide a web developer with a quick overview of the entire website. We have a sitemap video here. This can include a Style Guide that provides logo usage, color palettes, font styles, graphics, etc. These are simple, blocky representations of website pages that are devoid of graphics and color. A wireframe indicates key content and functions required on a page. Designers and developers will reference the approved wireframes.
Key wireframes should be created for both mobile and desktop devices to indicate how the structure and function is meant to adapt to different screen resolutions. We have a wireframe video here. For example, if the client is in the accounting industry, the usage of the color red may not be effective for buttons and calls-to-action. This document is prepared by the Technical Project Manager.
