What is a software development company?

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

While some software development 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 the 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 a client's pain points 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 it evolves or as the client's needs change and the solution evolves to meet those changing needs.

What are the different types of software development methodologies?

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

As 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 starts. However, in practice, phases may overlap to reduce effort and time by starting some activities in one phase before the previous phase ends.

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

There are several implementations of Agile. Scrum, Kanban, Extreme Programming (XP), and DevOps are all methods within the Agile family. While each method differs in its approach to the development lifecycle, they all emphasize continuous iteration of work processes and 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. Conversely, Agile is more suited to projects with a high degree of uncertainty and a high rate of change, complexity, and risk.

Agile can be more susceptible to scope creep and cost overruns. In contrast, 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 software?

The degree of implementation complexity is key 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 a relatively shorter timeline.

Medium-complexity software development delivers richer and/or more complex functionality compared to low-complexity projects. It involves 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 the user base. This translates into a longer project timeline than low-complexity projects. These projects also require larger project teams, which leads 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 project cost estimates will depend on the geographic areas where the software development company is located. For example, companies located in South Asia tend to charge less than companies in the U.S. The difference can be from $20 per hour for companies based in South Asia to up to $200 per hour for companies based in the 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 and the more advanced the expertise needed, the more costly it will be.

Finally, the size of the team is another factor that influences project cost. Again, the more complex the project, 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 development companies are created equal. While most companies claim to deliver any project, this is not necessarily true. Therefore, it is crucial for entrepreneurs, business owners, and managers to conduct a thorough due diligence evaluation before selecting a software development company for their project.

An effective process for organizations to choose the right software development partner is the Request for Information (RFI). The RFI process achieves two objectives. It provides prospective vendors with an overview of the main pain points that software solutions should address and 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;

Evaluate the RFI responses and make the final selection.

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

What questions should the software development company ask before signing a contract?

As part of the RFI questionnaire, vendors are asked to provide information enabling the team to assess their strengths and weaknesses. The evaluation team uses three main criteria to evaluate vendors.

1. Company Strength & Background

The prospective partner must bring deep experience and understanding of the client's industry. Therefore, the first thing to evaluate is the vendor's industry experience and how long the company has delivered solutions 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 similar software solutions;

Include the number of years your company has offered similar software solutions;

Number of customers with similar software solution needs.

2. Software Functionality Experience

Ideally, the prospective vendor team should have experience delivering solutions similar to those the client organization desires. 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 scale;

Number of years the solutions have been operational;

Reference contact information: Contact name, title, phone number, and email address.

3. Project Implementation Experience

Project implementation experience is an important criterion for selecting a software development company because it evaluates the vendor's experience with and approaches 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 and 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 and escalation procedures.

The consequences of selecting the wrong software development company are many, and unfortunately, they all lead to low-quality solutions, a delay in getting 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 who deliver turnkey projects and full-cycle software development services.
