Buyer's guide

There are more than 585,000 software and IT services companies in the United States alone, according to data from CompTIA. The market has so many choices, but entrepreneurs, business owners, and managers have only one chance to get it right.

Unfortunately, many entrepreneurs, business owners, and managers in a rush to get to market skip the careful evaluation required to find the best software development companies that best suit their needs. They jump into a partnership with a software development company just to find out they have selected the wrong partner.

This article highlights the main important factors that entrepreneurs, business owners, and managers need to take into account as they consider engaging the services of a software development company.


What Is a Software Development Company?

Businesses hire software developing companies when they require a unique a software solution to address specific needs better than traditional off-the-shelf solutions, or when none exist. Software solutions can range from web sites, mobile apps, and custom software solutions that meet the unique needs of the business.

While some software developing companies specialize in specific industries or niches within an industry, others build solutions for a variety of different industries such as healthcare, retail, and education. Software development companies may also specialize in specific technology niches such as Artificial Intelligence, Big Data, or Internet of Things.

During a typical engagement on a client’s project, a software development company works with the client to identify needs and requirements, design and build the software solution, and deploy it. A typical software development lifecycle involves the following set of activities:

  • Requirements analysis and specification: this phase is typically the first step in an engagement and enables software development companies to understand the pain points that a client is experiencing and capture their needs and requirements.
  • Design and development: this activity translates the requirements into design elements that software developers can use to build the solution.
  • Testing: once the solution is developed, the test phase is initiated to ensure that the end product meets the agreed upon requirements and design.
  • Deployment: these activities ensure a smooth transition of the solution to the end users.
  • Maintenance and support: once the solution is deployed, the client or software development company will provide ongoing maintenance and support as the solution evolves, or as the client needs change and the solution needs evolve to meet those changing needs.

What Are the Different Types of Software Development Methodologies?

Waterfall and Agile are the two well-known approaches that software development companies use to organize their software development lifecycle activities.

Similar to the way water cascades from the top downward in a waterfall, the waterfall method follows a sequential or linear process where one phase is completed before the next one starts. However, in practice, phases may overlap to reduce effort and time by starting some activities in one phase before the previous phase ends.

Agile, on the other hand, is an iterative and incremental approach to software development lifecycle activities where the solution evolves as the team improves their understanding of the requirements.

There are a several implementations of Agile. Scrum, Kanban, Extreme Programming (XP), DevOps are all methods within the family of Agile. While each method differs in its approach to the development lifecycle, they all emphasize continuous iteration of work processes. Additionally, they all aim to deliver value to customers quickly.

Each method is best suited for different types of projects. The waterfall approach works well when upfront planning is needed. Agile, on the other hand, is more suited to projects with a high degree of uncertainty and a high rate of change, complexity, and risk.

This means that Agile can be more susceptible to scope creep and therefore cost overruns, whereas the more structured nature of Waterfall can provide more predictability and consistency but can be less responsive to change.


How Much Time Does It Take to Build a Software?

The degree of implementation complexity is a key factor in determining the time it takes to build a software solution.

Low complexity projects tend to have a small set of requirements and deliver simple functionality. These types of software development projects only require a small team and can be delivered on relatively shorter timeline.

Medium complexity software development delivers richer and or more complex functionality, in comparison to the low complexity software development projects. They involve advanced features that require significant effort or more complicated technical integrations.

Medium complexity projects also require more time to fully capture the requirements, conduct thorough testing, and deploy the final product to all the user base. This translates into longer project timeline than low complexity projects. These projects also require larger project teams, which lead to higher costs than low complexity projects.

As a general rule of thumb, it is recommended to estimate 1-3 months for low complexity projects, 3-6 months for medium complexity projects, and 6-12 months or more for high complexity projects.


How Much Does Software Development Cost?

In addition to the project’s degree of complexity, other factors influence the cost of software development.

The cost estimates of the project will depend on the geographic areas where the software developing company is located. For example, companies located in south Asia tend to charge less than companies in U.S. The difference can be from $20 per hour for companies based in south Asia compared to up to $200 per hour from companies based in U.S.

Additionally, the required level of expertise will also influence the project cost. Developers with extensive expertise in a particular specialization area will command higher fees. Therefore, the more complex the project is and the more advanced the expertise needed, the more costly the project will be.

Finally, the size of the team is also another factor that influences project cost. Again, the more complex the project is, the more likely it requires a larger team, which translates to higher project costs.

As a general rule of thumb, it is recommended to estimate $25k to $60k for low complexity projects, $50k to $100k for medium complexity projects, and $100k to $250k or more for high complexity projects.


How to Choose the Right Software Development Company for Your Business?

Not all software developing companies are created equal. And while most software companies will claim that they can deliver any projects, this is not necessarily true for all companies. Therefore, it is crucial for entrepreneurs, business owners, and managers to conduct a thorough due diligence evaluation before selecting a software developing company for their project.

An effective process that organizations use to choose the right software development partner is the Request for Information (RFI). The RFI process achieves two objectives. It provides the prospective vendors with an overview of the main pain points that the software solutions should address, as well as any information on the desired features and benefits. The other objective is to solicit information that the vendor evaluation team will use to identify the top software development companies that can address their needs.

The process consists of four major steps: develop the RFI requirements and questionnaire, identify top vendors to evaluate, distribute the RFI to the top software development companies, and evaluate RFI responses and make final selection.

The final step of the RFI process is to shortlist two or three of the best software development companies for final evaluation. At this stage in the RFI process, the evaluation team will have all the information they need to make a final decision on which vendor to select.


What Questions to Ask the Software Development Company Before Signing the Contract?

As part of the RFI questionnaire, vendors are asked to provide information that will enable the evaluation team to assess their strengths and weaknesses. There are three main criteria to evaluate vendors.

Company Strength & Background

It is important that the prospective partner brings deep experience and understating of the client’s industry. Therefore, the first thing to evaluate the vendor’s industry experience and how long company has been in the business delivering solution in the client’s specific industry.

Vendors should provide a brief description of their company and answer the following questions:
  • Describe your company’s history in developing a similar software solutions.
  • Include the number of years your company has offered similar software solutions.
  • Number of customers with similar software solution needs.

Software Functionality Experience

Ideally, the prospective vendor team should have experience delivering similar solutions to the one desired by the client organization. The vendors should provide three customer references with solutions similar to the client’s project, including:
  • Brief description of the solution and how the implementation compares to the client’s project in terms of scale.
  • Number of years the solutions have been operational.
  • Reference contact information: Contact name, title, phone number and email address.
Project Implementation Experience

Project implementation experience is important criteria for selecting a software development company because it provides an evaluation of the vendor’s experience with and approach to requirements gathering, design, testing, deployment, and ongoing maintenance and support.

Key questions to ask are:
  • Describe your project management methodologies or processes to ensure implementation quality, as well as, on schedule and on budget project completion.
  • Describe your process for gathering functional and technical requirements.
  • Describe your proposed approach to data migration and how Port direct costs are minimized.
  • Describe your testing methodology for each test type in your test plan. Clearly describe deliverables, roles, and responsibilities.
  • Describe the training methods and materials that you provide.
  • Describe post-implementation support including phone and/or website support, as well as escalation procedures.

The consequences of selecting the wrong software development company are many, and unfortunately they all lead to low quality solutions, delay to get to market, or defective software that requires extensive and expensive rework. In our list you will find the most experienced and trusted software developers with a solid background and deep technology expertise that deliver turnkey projects and full-cycle software development services.
