In this post, you will learn about technical analysis in software engineering and the role of a tech lead/technical expert and solution architect in the software development process.

You already know about the importance of Business Analysis (BA) in software development. It’s hard to overestimate the role of a business analyst who helps formulate and translate stakeholders’ requirements, align expectations, and as a result, launch a valuable software product.

However, there’s another major analysis in software development that helps create successful products and deliver a project effectively. This analysis is called technical analysis or technical investigation and is usually fulfilled by a tech lead, solution architect or other tech experts in the team.

What is technology analysis in software development?

As you know, business analysts work on functional requirements, whereas the responsibility of solution architects is to conduct technology analysis: define an integration strategy, find the right platforms and frameworks for the future system and document non-functional requirements.

So what is technology analysis and what does the process of technical investigation include? To put it simply, technology analysis is the process of assessing technologies and tools that could/would be used to develop a digital system. It is usually performed by senior tech specialists who use technical investigation to select an optimal tech stack and development approach based on project requirements and goals.

Common technology analysis methods

Depending on the stage and specifics of the project, engineers and architects use different technology analysis methods and processes:

  • Analyze project requirements
  • Break down the system into functional components to analyze each module
  • Gather insight and list available technologies, platforms, frameworks, tools that could be used to develop each component (search, peer experience, documentation, professional forums and domain-specific resources, etc.)
  • Review relevant open-source and/or proprietary libraries, APIs, prototypes, etc.
  • Make a comparative analysis of technology alternatives based on key criteria (license, price, availability, reliability, performance, code quality, support, scalability, flexibility, etc.)
  • Determine risks and define limitations

Key steps of information technology analysis

Here are the key steps to make during technical analysis in software development.

Analyze the client’s technology infrastructure

Almost every client has at least some technology infrastructure to start with. By infrastructure, we usually imply hosting, email services, SSL certificates, database servers and any other technology component on the client’s end that will interact with the future system.

In order to understand how to work with the given infrastructure, a tech lead performs the technical investigation and tries to understand how to further use this infrastructure in designing and building a new system or upgrading existing software.

Usually, if the existing infrastructure is well-built and compatible with a new product, it can be completely re-used. Sometimes, the legacy systems are simply too old and won’t go along with a new product. Then, such infrastructures require a complete upgrade. If this is the case, it’s good to learn about it at the very beginning of the project to implement relevant prioritization of project requirements.

At this stage of information technology analysis, tech leads or solution architects also try to find out how to integrate the client’s services into a new system.

In a common technology analysis example, experts and analysts need to figure out how to integrate a new client application with the old infrastructure and database. For instance,  when a company needs to develop a new app for customers that will be using their old backend. In this case, a technical analyst should define the capabilities and limitations for such integration. It is worth discussing the integration opportunities with a backend development team in the first place. In some cases, when direct integration is impossible, the scope may include the development of a private REST API to connect the backend with the app.

Make a technological analysis of solutions and platforms used to build a new system and its components

There is no point in reinventing a wheel. Custom software should benefit from a wide range of platforms, frameworks and services available in the market.

For example, we are building an app or a website that should display certain content managed by an admin. This app or website may be stuffed with custom unique features which require serious design and development efforts. However, adding the component responsible for content management is a no-brainer. Today, it can be built on top of a time-proven CMS platform such as WordPress, Sitecore, etc.

There are plenty of examples when platform integration actually speeds up the development. Different CRM systems, eCommerce platforms, mail services are among the most common out-of-the-box solutions used and customized for these purposes. The main task of a technology expert at this stage is to find and compare potential third-party software solutions, validate them against given business requirements and choose the right ones for the project.

Analyze third-party APIs required for the development

Nowadays, almost any new system requires certain integrations. It can be a payment gateway, social networks or domain-specific services and platforms usually integrated via API.

Sometimes, the list of API is provided by the client. Often, it’s the responsibility of a tech lead to finding an appropriate library or framework that can be useful in the course of the project development.

For this purpose, it’s useful to dig through the Internet, choose the most popular libraries or other solutions in a specific business domain, study the approaches competitors of other companies use to solve similar problems and learn from the experience in the company.

When defining the list of libraries, APIs or frameworks that could be used in the project, tech experts should know how to compare software solutions. Once the final list of integrations is defined, tech specialists perform the technological analysis that usually consists of the following steps:

  • Reviewing relevant documentation,
  • Matching endpoints/features and product requirements,
  • Analyzing how these solutions could be used in the future (important for the features, which are out of the project’s scope now but can be included later)
  • Validating API, framework, platform or other solutions’ limitations against the given requirements,
  • Validating API, framework, platform or other solutions’ performance capabilities against the given requirements/established project goals,
  • Analyzing how to integrate API, framework, platform or other solutions in the existing infrastructure.

Document non-functional requirements

As a rule, business analysts discuss business goals and requirements with a client. Technology analysts, in turn, collect and document non-functional requirements.

Non-functional requirements are abundant. The most common and important ones are the following:

Security

Security requirements include:

  • protection against unauthorized access to the system and its data,
  • authorization and authentication across different user roles,
  • data privacy,
  • prevention and protection against cyber attacks and malware.

Reliability

This requirement determines the ability of a system to perform under certain conditions in a certain environment. It includes:

  • consistent system performance without failure for a period of time,
  • the impact of bugs, hardware malfunction, other problems with system components,
  • the quality of task implementation.

Performance

Performance measures the quality of system interaction with users. It includes:

  • user experience quality,
  • system safety against overloads,
  • system responsiveness to different user interactions.

Scalability

These requirements imply system growth capacity. It includes:

  • the ability to provide more users with a service of the same quality,
  • processing more data or transactions,
  • the capacity for memory, space, speed growth.

These are the important non-functional requirements for almost every software development project. If these requirements are not taken into consideration during technology impact analysis and technical investigation at the beginning of a project, it entails serious risks which may end up with additional costs and time loss.

Results and deliverables of technical investigation

When tech leads or solution architects are done with all the steps of technical investigation and IT analysis, they record the results and create the following artifacts:

  • Technology stack description. This description includes the programming languages, databases, servers, hosting and third-party libraries recommended to use on the project.
  • The architectural diagram of a product. Usually, the diagram shows different project components with their roles and functionality and the relations between different components of the future system.
  • Non-functional requirements specification. This is a separate part of the functional specification which describes non-functional requirements – security, reliability, scalability, performance, etc.
