Comparison: custom software development companies' attitude to delivering results

Reviews are not enough - what are the qualities of the best custom software development company?

The approach to delivering software and attitude towards cooperation with clients - that's what differs one dev shop from another.

You most likely have experience researching and figuring it out on your own, don't you? In the sections below, you'll find all the details with useful explanations.

Focus on business goals, not delivering features

Why is vendor's focusing on business goals important for your project?

• It ensures the product aligns with business goals and objectives.
• It also helps prioritize features that bring the most value and profitability.
• Vendor organizes the project to deliver the best business outcomes.
• It prevents developers from working on features without understanding the purpose behind them.
• You avoid building an unsuccessful product that doesn’t meet market needs.
• But the likelihood of a higher return on investment (ROI) increases.

Real business support manifests in:

• challenging your ideas and advising what you can do better during the discovery phase and then on a daily basis,
• gathering a cross-functional team by one table to talk about your business goals and plan how to deliver them in the most time- and cost-effective way,
• including a business analyst in a team from the very beginning,
• having developers with proper business knowledge or supporting them with tech advisors.

In today's world, it's super easy to say that, hey, I didn't deliver something in scope and in time because it's agile and everything changed. But actually it's not true. It means that you didn't control the change in a way that will not be affecting your project so much. So what we are focusing on is to actually deliver what we what we agreed in terms of the scope, time, and budget with our customer. And it doesn't mean that it will not change, but we need to be able to control how the change is happening. - Aleksandra Gepert-Kraujutowicz, Head of Delivery at Brainhub

Consultancy approach - knowledge-sharing culture

Why is a vendor's knowledge-sharing culture important for your project?

• Your team gains valuable new skills and insights.
• It improves the quality and efficiency of your software development processes.
• You understand how development is done, providing greater control and clarity.
• It enables your team to eventually take over development independently.
• It also encourages collaboration, boosting teamwork and project success.
• Finally, it increases transparency throughout the development process.

DevOps culture - smooth cooperation and no knowledge silos

Why working in alliance with DevOps should be important to you?

• DevOps culture breaks down barriers between development, operations, and business teams for smoother collaboration.
• It speeds up decision-making processes and accelerates development.
• The feedback loop becomes shorter, allowing for faster adjustments and improvements.
• Frequent deployments and testing help identify and fix bugs quickly.
• Overall efficiency of the development process increases.

<span class="colorbox1" fs-test-element="box1"><p>A custom software development company that works in line with DevOps culture and loves to share knowledge is pure gold. You can make your processes a lot better by working with them.</p></span>

Time to impact - how quickly they make a change?

Time to impact depends on:

• how a company manages its resources (for example, if it maintains a sufficient buffer of developers who can jump right in),
• number and complexity of formalities needed before they can start (often bigger dev shops need more time for formalities than the smaller ones),
• time needed for onboarding.

Time to impact can be shortened by adding tech advisors to a team in the very beginning - they can quickly spot problems and suggest improvements. It can be also influenced by the way a company manages projects (fast iterations often mean fast improvements).

Organizing workshops in the initial phase of the process also allows for a quick impact from the dev shop's side.

Quick time to impact can manifest itself by:

• The development team quickly delivers a Minimum Viable Product (MVP), allowing you to start gaining user feedback and generating value early in the project.
• The software delivers key functionalities early in the project, enabling your business to achieve specific objectives or gain a competitive edge swiftly.

Taking ownership - a crucial quality of a top custom software development company

Why is a high ownership attitude important for your project's success?

• High ownership culture encourages developers to take full responsibility for their work and mistakes.
• It promotes transparency and open communication with your team.
• Mistakes are quickly acknowledged and fixed.
• It fosters a solution-oriented mindset in the development team.
• Creativity and proactive problem-solving increase.
• The ownership attitude builds trust, knowing that potential issues will be openly discussed and addressed.

Being a highly engaged partner

A true partnership means becoming a part of your team and being highly engaged in working towards achieving your business goals in the most efficient way.

Why is that important?

• In traditional outsourcing a task is delegated to an external partner and they just deliver. You can't be sure if everything is going in the right direction. Development teams that form close relationships with their clients transparently share with you their progress. You can keep the finger on the pulse and be sure of the results.
• In the case of team augmentation, your team and an external team will collaborate more effectively and gain more satisfaction.
• Engaged teams focus on acieving their clients business goals.

During the assessment phase, pay attention to culture fit, mutual understanding, and the flow between you and the vendor’s team.

Before starting the cooperation, remember that you should be the owner of the source code, and that needs to be stated in the agreement.

If you want to speed things up, prepare at least a short version of an RFP with all the crucial details. This will save your time as you won't have to write a long e-mail for each vendor.

Good luck!

FAQ - Choosing a custom software development agency

What is custom software development?

Custom software development is the process of designing, creating, deploying, and maintaining software specifically tailored to meet the unique requirements and preferences of an individual, organization, or a specific set of users. This process stands in contrast to commercial off-the-shelf software (COTS), which is developed for a broad market and does not cater to individual-specific needs.

How much does custom development cost?

The cost of custom software development can vary widely based on a range of factors. It's challenging to provide a precise figure without specific details about the project, but I can outline the key elements that influence the cost:

Complexity and scope of the project:

1. Simple projects (like a basic web application or a simple mobile app) may cost from a few thousand to tens of thousands of dollars.
2. More complex projects (like an enterprise-level application, a sophisticated mobile app with advanced features, or a comprehensive e-commerce platform) can cost from tens of thousands to hundreds of thousands of dollars.
3. Highly complex projects (like custom CRM systems, complex integrations with existing systems, or advanced AI solutions) can exceed a million dollars.

Technology stack: The choice of technologies (programming languages, frameworks, databases) can impact the cost. Some technologies may require more specialized skills, which can be more expensive.

Development team's location and structure:

1. Geographic location: Custom software development agencies in North America and Western Europe typically charge higher rates than those in Eastern Europe, Asia, or Latin America.
2. In-House vs. outsourcing: Hiring an in-house team is usually more expensive than outsourcing to a development company or freelancers, considering the added costs of employment benefits, office space, etc.
3. Design customization and User Experience: Custom design with a focus on user experience and unique branding elements can increase the cost.‍
4. ‍Integration with other systems: Integration with existing systems, third-party services, or APIs can add complexity and cost.‍
5. Data migration and processing: Migrating existing data into a new system and ensuring its integrity can be a complex and costly process.

Security and compliance: Implementing advanced security measures and ensuring compliance with regulations like GDPR, HIPAA, etc., can increase the cost.

Maintenance and support: Ongoing maintenance, updates, and support services are typically charged separately and can be a significant part of the overall cost over time.

Project duration and development methodology: Longer project timelines and methodologies like Agile software development (which may involve more frequent changes and iterations) can influence the overall cost.

Additional features: Features like artificial intelligence, machine learning, IoT integration, high-end graphics, or real-time data processing can significantly increase the cost.

How long does it take to build a custom software?

On average, a moderately complex custom software project might take anywhere from 6 to 12 months. However, this is a very rough estimate, and actual timeframes can be shorter or much longer based on the specific project requirements.

The time required to build custom software can vary widely depending on several factors:

1. Complexity of the software: Simple applications might take a few months, while complex enterprise-level systems could take years.
2. Scope and scale of the project: The number of features, integrations, and the scale at which the software is expected to operate greatly impact the development time.
