Selection Criteria For Software Development Companies

Hundreds of companies out there will promise to handle your software development project. Which ones can actually deliver an outstanding product, however, is an entirely different matter.  To help you find them, we have outlined our extensive criteria that enabled us to separate the wheat from the chaff and choose the finalists you see in the list above. We’ll take you through the factors we used for the selection process so you can learn how to do it yourself.

Software Development Company Website

The most obvious place to start your search for the best software development companies is the target company’s website. You want to take a look at the About Us page and learn how many years of experience the firm has. Anything over three years of market experience gives you a baseline to know that the company has some projects under their belt. Keep in mind though that even if software development startups might be inexperienced, there are many things that they can bring to the table.

Moving on to the services section, make sure the software developer company provides the services you need. Then, take some time to go over their case studies and portfolio. At this stage, pay extra attention to the company’s industry focus. The majority of software development companies specialize in a niche like healthcare, transportation, SaaS, or gaming. If your project falls within the company’s areas of expertise, you’re on the right track with your search.

Then comes the business size of the agency’s typical clients. If you have a small startup company, you want to find an outfit that caters to small businesses whose needs differ from those of an enterprise. 

Company Service Focus

Software development can be classified into several categories based on its intended purpose. 

Custom software is developed with the client’s personal or business needs in mind, while commercial software targets a specific market. Then comes system software that sees software development agencies build a base for the programming processes. Finally, embedded software is meant to be a part of a physical product and is integral to its functioning.

Among these, custom software is the most popular by far. This is an umbrella category for a wide range of services, including web development and mobile app development. 

Custom Software Development

If you’re having trouble deciding where your project falls, opt for a company that provides custom-built development. This type of process will also allow you to keep control over how your project is shaped during the entire software development life cycle.

Even if your software project is intended for third-party users, it’s still better to choose a custom build than a ready-made solution. This is because the custom software development companies will be able to provide valuable insight into your target market and make sure that your software can scale adequately as well as keep up with the needs of the business.

Platform-Focused Software Development 

There are three main types of platforms that software can be based on, each having its specific requirements. 

Web App Development

Software made for web-based use is an extremely popular option. These applications can be accessed from any browser, meaning there is no need to install the app on your device. Another feature that brands and users also like is the easy updating process, which typically happens automatically. Software developer companies that offer this service will work on the front end and the back end programming for you, which is why it’s essential to check the potential firm for the programming expertise.

Desktop App Development

Desktop applications require users to manually install the software by downloading it on their device. Since these applications don’t necessarily require internet access, the software development firm needs to focus on the app speed, user experience, and interface design. 

Mobile App Development

As the case is with desktop apps, mobile applications need to be downloaded and installed on a mobile device. The apps can run on operating systems like iOS, Blackberry, and Android, and are featured in the respective app stores. The focus here is on user-friendliness which should also cover the app updates.  

Skills & Technologies

It goes without saying that the top software development companies should employ highly-skilled professionals, and stay on top of the latest technologies. 

Programming Languages 

Python, PHP, CSS, SQL, and JavaScript are just a few of the many programming languages used in software development. Each has its own specificities, which means that different languages will be better suited for different business goals. When you’re doing your research on developers, don’t forget to check which languages their team specializes in and if they suit your business needs.

Software Architecture

The top custom software development companies will know the value and importance of well-built software architecture. It is a comprehensive plan which includes many parts that need to work in unison. From software reliability, fault tolerance, system organization, technology implementation to the assessment of potential risks, great software architects will include all of that and much more.

User Experience

Let’s face it, the technology can be amazing, but if it fails to provide remarkable user experience, it will just go to waste. Regardless of what you are planning on developing, UX design should be one of your developer’s central points. Software engineering firms that understand the importance of user experience will get you in touch with their UX designer and ensure that you get the best possible product.

Project Management

Don’t ignore the importance of robust and adaptive project management. Those that are genuinely the best will understand your software product’s life-cycle, which will include several testing stages, collecting user feedback, and updates. Seeing that software development necessarily includes many sets of changes, the Agile management methodology fits this description the best.

Additional Software Services

Many companies also offer additional services to their clients. Depending on your plans, you might need one or several of them on top of the basic software development services.  

Cloud Computing

Cloud computing refers to data centers. That implies that resources can be accessed on-demand, typically through cloud storage. Top developers that specialize in creating software solutions based on cloud storage will tend to have one of these certifications:

  • DevOps Certification
  • GCP CertificationMicrosoft
  • Azure Certification
  • AWS Certified Developer

Artificial Intelligence

AI is indispensable for enterprises that work with large data systems and requires top-notch specialists. In case you’re interested in artificial intelligence services, make sure you ask your potential developer if they have extensive experience with Hadoop, Apache Spark, Python, PyTorch, or Tensorflow.

Internet of Things (IoT)

With IoT becoming more and more popular among software development firms, there is also a growing demand from the customers for such expertise. Many offer the service; however, you should be careful and check if your possible development partner is staying on top of their game by asking them about their hands-on experience with IoT software products.  

Team-Based Skills

Last but not least, we’ve included several important team skills your agency should have. The companies should aim to build a team that has the technical expertise and customer-oriented skills, which will provide an enjoyable experience overall.

Communication and Realistic Expectations

Good communication is extremely important for a collaborative project of any type, but especially for top software development firms. Ask to speak with the company you’re interested in and see how you like their responses to your questions. 

However, you do want to be able to spot a red flag when you hear it, and in this case, overindulging clients to the point where the project suffers is one. Realistic expectations are extremely important, so you want to stay away from companies that promise huge things right off the bat.

Respecting Deadlines

Even though software development projects typically last longer than initially planned, sticking to deadlines is crucial for a good result. This is especially true for products that are market-oriented and have delivery timelines that need to be kept. 

Client Feedback and Social Media

You’d be surprised how many agencies tend to oversell their experience in the field, claiming to be the best software development companies. To avoid being duped, ask the agency to provide customer reviews or find them yourself on third-party websites. 

You also want to take the time to check out their social media profiles where you might find experiences of past and present employees as well as their general values as a company.

Value for Money

Cost matters, and you should get the best value for your budget without compromising on quality. Picking a firm just because it’s cheap isn’t the answer. Software development companies that go significantly under or over the industry standard should be avoided at all costs (pun intended). The discrepancy typically indicates a scam or just an inexperienced outfit that doesn’t know how to estimate its worth. Taking the time to understand your potential partner’s pricing structure is essential if you want to get the biggest bang for your buck.
