Software Design Specification Requirements – Design Types & Trends

Once you’ve done the SRS documentation, the first thing that comes into your mind is- ‘ now, what’s next?’ The answer is ‘Design.’ After completion of the SRS documentation, you need a perfect design plan for execution. Need a design specification that helps to define the overall system architecture. Without any doubt, Design specification is one of the most important phases of software development. In this phase, the requirements gathered in an SRS document are used as input, and software and software architecture that’s used for implementing system development is derived.

“How will we get what we want?” This phase of the SDLC gives you the answer. It starts by making changes in the software specifications & turning it into a design plan called the ‘Design Specification’. All the members of the team along with the stakeholders- once go through this plan and suggest their valuable feedback. The overrun of the project at best in this phase & failure of the project at worst.

Types of Design documents

Mainly, there are two types of design documents developed in software development systems. One is low-level design & another one is high-level design. Low-level design documents include different entities like functional logic, database based on type and size, all types of dependencies, and listing of error messages. On the other hand, a high-level design document covers details like brief description, outline about functionality, interface relation between modules, tables with key elements, and architecture diagram with all details.

What needs to be there in design specification

There are many components that are responsible for design documentation, but few of them are more important. Let’s take a look at it :

  • User interface information

This piece of information includes details regarding color pallets, fonts, typography, measurements, etc.

  • Design assets

One of the most important things in the design process design assets. These components include icon and button styles, media, etc. And can cover all the design requirements that cannot be coded.

  • User experience layouts

Your user is your main goal, so setting a good User experience layout is a must-needed thing.

This information regarding flows of users, their activity, their behavior, and placements of features is in line with this behavior. This way developers can easily know the actual reason behind features and prioritize based on that.

  • Other important information

Any information that isn’t included in the above categories can be added here. It can include research findings, prototype links, older references, formatting, etc.

Where Do Design Specs fit

The main thing is where you can put design specifications in the UX process. For that, you need to understand the whole flow. Design specification stands in ending in this process flow. Let’s understand it with an example. A developer creates a mobile shopping app. It may utilize several artboards with some characters, fonts, colors, icons & design elements. A proper design specification helps developers & designers to understand the flow of the app. It reduces the time by saving developers from marking up the design. This results in designers can spend more time on user- experience, and developers on how to implement it.

Updated Design Trends

Talk about trending technology & we missed out on Google- it’s impossible. Android 12 from Google shows some excellent updates. Android 12 brings the biggest design change in the history of android. After going through the entire experience, one thing we can surely say- Android 12 is more expressive, dynamic, and personal. There are hundreds of thousands of examples showing the importance of design specification in a successful product. Airbnb takes care of the ambiance of its website with attractive design upgrades.

The SDLC Design Phase results in one of the two crucial elements of the project. Without a detailed design specification, the second key element ( the system) can’t be built, implemented, or worked. The decisions that you make in the design phase regarding technology, frameworks, configuration, implementation, and change management assure a strong foundation for the project.
