Custom Software Development Services for Enterprise Companies

Developing software tailored to your business.

Superior productivity, performance, and growth require best-in-class resources and tools. Custom software development is often used for companies with unique business processes that aren’t easily mapped to specific technology products. It’s an effective approach — we’ve spent the past 25+ years crafting custom software. It’s because our clients see how effective we are at it.

We offer full life-cycle consulting, software development, project management, testing, and implementation/rollout services, all based on deep institutional and operational understandings, such as only the most trusted, long-term partner could provide. Our focus is on understanding your routine processes, existing systems, and architecture so we can map out and articulate the full scope of data flow innovations that could translate into significant bottom-line and competitive advantages for you. We then work closely with your stakeholders and decision-makers to prioritize desired improvements, which are then executed as full-scale development initiatives.

As you engage with us, you will experience the outstanding technical skills, business domain expertise and smart project management of QAT Global’s team– from initial requirements definition and business process modeling to user training and solution support and maintenance.

QAT Global typically uses an Agile approach to projects which splits the project into several sprints (well-defined periods of time with fixed goals and deliverables). This Agile approach has the following advantages:

  • Transparency: Each sprint’s delivery is done on schedule.
  • Reliability: Each sprint’s delivery goes through acceptance procedures to confirm all the requirements have been met.
  • Time-to-market: Each sprint’s delivery contains a portion of the required functionality and is functional.
  • Flexibility: Adjustments to features and design can be easily accommodated.

Custom Software Development Technologies and Development Process

Our expertise comprises a comprehensive set of technologies, frameworks, methodologies, and best practices that enable us to develop the most challenging and complex projects and fulfill client requirements, expectations and preferences.

To cut costs and ensure effective results, we assign distributed development project teams that best fit the project’s goals and software requirements. Our software developers, architects, business analysts, coordinators, and project managers use QAT Global’s Agility RPM.

For more information about our skills and methodologies, please see our Technologies overview and How we work section.

Software Architecture

The most common area for failure in custom software application development projects is the hand-off between enterprise architecture and application architecture. Taking the hard work of an enterprise application framework and reference architecture and developing a true application requires detailed methodology, firm understanding of application development principles, and strict adherence to standards for software development. QAT Global Application Architects have the proven experience to bridge the gap between enterprise and application architecture, using Agility RPM℠’s proven methodology and standards and applying either our jDaptive or nDaptive application platform or a custom one developed specifically for you. Our services mitigate the most common risk to successful application deployment and position your critical software for success.

The QAT Global Software Architecture service includes:

  • Create candidate and solution architectures.
  • Analyze technical environment for reusable components, services, and platforms.
  • Integrate an Enterprise Service Bus (ESB) and define adapters.
  • Assure compliance with reference architecture and enterprise standards.
  • Plan the integration of legacy applications and phase out roadmaps.

Application Requirements Analysis and Design

QAT Global provides consulting for requirements analysis and design in custom software development projects. Modern software has progressed quickly from the traditional monolithic architectures and into the loosely coupled, service-based designs inherent within an SOA environment. The task of analyzing requirements and designing custom software has changed dramatically along with the underlying architectures. As you prepare to begin the requirements and design tasks for your new system, there is no end of options for external consulting partners skilled in traditional application design, but QAT Global stands alone in this area as the premier provider of custom software development within modern environments.

The QAT Global Software Application Requirements Analysis and Design service includes:

  • Define and design service components, services, and frameworks.
  • Design web services for maximum reusability.
  • Design and prototype UI (Web, Window, etc.…).
  • Design database structure, relational layout, and performance profiling.
  • Develop prototype code to guide development efforts and prove concepts.

Multiple design methodologies exist for requirements analysis and application design (such as Agile, RUP, and others). At QAT Global, Agility RPM℠, which combines the iterative development components of Agile, the proven requirements definition techniques of RUP, guided by one of our Architects or a Project Manager with the years of experience in the unique design challenges of custom software development, enables us to create superior project specifications so our team has an excellent technical understanding of your projects.

Business and Systems Integration

QAT Global provides consulting for business and systems integration. Organizations moving to an SOA-based architecture face the ubiquitous problem of integrating existing and legacy applications and data sources into the new architecture. In addition, most organizations today also have increasing integration needs with partner-provided applications or hosted applications and data sources. A true SOA system must incorporate new services with existing applications, partner data sources, and hosted applications. QAT Global’s Business and Systems Integration services ease the transition to SOA by interfacing legacy and external resources into new systems.

QAT Global has significant experience with incorporating external applications and data sources into your internal architecture to extend your business beyond the walls of your organization.

The QAT Global Business and Systems Integration service includes:

  • Develop web service wrappers for existing data sources and functions.
  • Integrate services into an ESB and SOA infrastructure.
  • Integrate legacy applications through web services or custom adapters.
  • Integrate partner applications and data sources into new applications.
  • Expose core functionality of existing systems for use by other applications.
  • Leverage existing code and databases within your modern SOA environment.

Iterative Application Services

QAT Global provides outsourcing and consulting for custom software development projects. Custom software development requires specialized skills and techniques. These include proven, hard-to-find skills such as web services, SOA, XML, .NET, J2EE, and ESB integration. No matter the development or deployment platform, the experience of QAT Global consultants trained in Agility RPM℠ maximizes the value of a new system by accelerating the deployment time while meeting or exceeding all user requirements.

QAT Global uses our repeatable process methodology we call Agility RPM℠. Agility RPM℠ is not a new non-standard development approach but is rooted in Agile software development methods and industry best practices to help ensure timely delivery of high-quality products to our clients. Agility RPM℠ is also agile and flexible enough to account for the uniqueness of your project while still being repeatable with clearly defined processes, artifacts, and client involvement to ensure that we are developing the right product at the right time.
