Software application development solutions that impel efficiency

INTELLILINK provides Application Development and Maintenance Outsourcing services that escort to business process enhancement. This allows in reduction of costs and enables business growth. INTELLILINK's Application Development and Maintenance Services is a part of its IT Services Group.

Any enterprise requires focus on its core business rather than focusing on its IT Services. We enable enterprises to focus on the core business related initiatives and we take care of all the maintenance services. We undertake strategic consulting to facilitate improvements in the efficiency of IT Systems and IT Services.

Application Development and Maintenance Services offers the design and development of new application features at sensible cost. We offer migration services from legacy systems to next generation systems and platforms. We manage mission critical business process improvements at a nominal cost.

Our Methodology

The Application Development and Maintenance Practice of the IT Services Group have great proficiency in all industry standard development methodologies viz., Waterfall, Iterative, Spiral, Prototype, Component based, Rational Unified Process (RUP), Rapid Application Development (RAD), Agile and XP. We offer strategic consulting to our clients in IT Services which provides scope for efficient business process.


The iBUILD delivery model is an INTELLILINK’s proprietary design crafted by the Center of Excellence (CoE) for application development and maintenance of our IT Services Group. The iBUILD methodology is based on DTAGUARD's fundamental principle of facilitating clients with business process improvements through strategic consulting for IT Services Outsourcing. This model brings the best practices of a global delivery model with 14 years of offshore based project execution. It is based on CMM level 5 software development processes and proven Six Sigma approach in Application Development and IT Services. Certain Six Sigma techniques have been incorporated into the iBUILD methodology for better management of customer requirements and ensuring robust fail-proof design. They include Quality Function Deployment (QFD), Failure Mode and Effect Analysis (FMEA), Pugh Matrix and Fishbone Analysis. iBUILD breaks the application development process into five phases with specific toll gates for each phase, based on the requirement of customer, interaction and utilization of offshore resources wherever possible.

Process of Development

Requirement Gathering Phase:

Requirement gathering is done at client site with an experienced and skilled team from INTELLILINK which also undertake requirement analysis. For complex initiatives and in case of multi-site requirement gathering, INTELLILINK employs a ‘Quality Function Deployment’ (QFD) to identify ‘Critical to Quality’ (CTQ) requirements of stakeholders. ‘Voice of Customer’ (VoC) tools and techniques are used to understand customer ‘wants or needs’ that are subsequently flowed down using QFD from user requirements to design.

Design Phase:

Design is usually performed offshore with onsite participation driven by degree of customer involvement in defining architecture. Architecture definition/ high level design is driven by reference architecture from a knowledge base available in iNODE, the technology from Center of Excellence (CoE) within INTELLILINK. For critical and complex components, Failure Mode and Effect Analysis (FMEA) technique is used to make the design more robust. Pugh Matrix trade off analysis technique is used to choose the best of the design options for solution. Application development and testing are executed offshore. Learning and reusable artifacts from past engagements are extensively used, leveraging the Knowledge Management framework within INTELLILINK.

UAT and Implementation Phase:

Depending on the client’s requirement, INTELLILINK enters into a long-term support (or maintenance) contract. We offer a cost effective solution leveraging offshore, and can bring in year-on-year cost reduction by continuously improving the support processes leveraging Six Sigma DMAIC methodology and other tools & techniques. A metrics management program ‘Open Envelop Methodology’ (OEM) and DMAIC causal analysis tools driven by INTELLILINK are used to identify areas for improvement.

Multi Threaded

The Application Development and Maintenance Team of the IT Services Group are proficient in Multi Threaded Time Boxed Methodology. This industry standard methodology offers business process improvement in all the areas of software development.

The Guiding Principles of the Multi Threaded Time Boxed Methodology are;

  • Short time boxes of 4-6 weeks
  • Multi threaded Time Boxed Process
  • Parallel delivery of development and test artifacts
  • Continuity and consistency of core and integration teams

The expected business benefits are cycle time reduction, faster time to market, high quality and scope to accommodate changes. The prioritized requirements will be funneled through to various teams to perform detailed requirement analysis. The approach is such that when one team completes requirement gathering and starts with design, the next team carries out the rest of the requirements. Finally, the requirement will be delivered in various packets of logical unit.

Rational Unified

INTELLILINK follows the Rational Unified Process for offshore software development through its custom development services. INTELLILINK Quality Management System (QMS) maps this process with the CMM model to provide services with CMM level 5 maturities. The QMS also brings the Global Delivery Model to enable onsite/ offshore based development for IT Services Outsourcing. We use various tools for development activities such as Clear Case for configuration, Requisite Pro for requirement analysis and Rational Rose for analysis, design and construction.


The Application Development and Maintenance Practice under the IT Services Group have several offerings which offer business benefits including business process improvement. The key services that are provided under the Application Development Practice are custom development, re-engineering and product development. The key services that are provided under the Application Maintenance Outsourcing Practice are 24x7 production support, Level 2 and above product support, helpdesk support and performance monitoring and alerting.

Packaged Application Services

In a constantly evolving business landscape, it is imperative for organizations to future-proof their business and realize the full potential of technology breakthroughs while sustaining profitability in a competitive world. Prepackaged business applications from leading global product vendors provide some of the best-in-class business processes. Intellilink helps clients automate their value chain through off-the-shelf application packages, realize value through configurable package-centric solutions, and facilitate cutting-edge technologies to evolve a comprehensive IT landscape for your enterprise. In addition, enterprises need technology expertise backed by deep industry knowledge to successfully execute business agendas with robust IT strategy initiatives.

At the same time, to achieve competitive advantage, organizations are increasingly looking towards adoption of technology-driven business models to build their IT infrastructure and enterprise architecture.

The enterprise technology landscape in several organizations lags behind business demands. This necessitates creation of a flexible and efficient technology landscape that responds to business demands in an agile and efficient manner.

Intellilink partners with clients across industries to solve complex business challenges by reforming their technology landscape in sync with business strategies. Intellilink achieves this by leveraging robust business application expertise across prepackaged business applications, functions, and technologies.
