As software development becomes distributed globally, opting for the apt testing delivery model will be pivotal. While onshore, offshore, and nearshore each have benefits, a hybrid approach optimized for unique needs delivers maximum value. (Image by DCStudio on Freepik)

This blog deconstructs various models, factors to consider, and how leading software testing companies in India help design customized solutions. The objective is to enable informed decisions around leveraging diverse locations and blending delivery approaches.

Onshore Delivery Model:

Onshore involves testing resources based on the client’s domestic market. The pivotal perks will include:

• Proximity will permit frequent collaboration and quick turnarounds. Issues are addressed in real-time.
• Shared time zones will allow testing during the client’s work hours for seamless discussions.  
• Cultural familiarity will streamline communication and requirements comprehension.  
• Regulatory compliance, like data residency, is straightforward.  

However, onshore has limitations. Domestic resources and infrastructure increase costs, limiting budgets. It also provides no flexibility to scale globally or test round-the-clock.

Onshore suits projects requiring close collaboration on critical applications and frequent stakeholder interactions. It remains crucial for specialized domains like healthcare, finance, etc. due to compliance needs.

Offshore Delivery Model:

Offshore shifts testing to a different country, typically with lower costs, like India. The pivotal perks will include:

• Lower labor expenses allow up to 70% savings, freeing budgets for additional testing cycles.
• Established offshore centers offer thousands of skilled resources, infrastructure, and processes to scale seamlessly.
• Through distributed global locations, testing can be performed 24/7, leveraging the follow-the-sun methodology.
• India has domain-specific expertise across industries gained from extensive multi-national experience.  

However, offshore challenges include potential communication gaps due to distance, cultural differences, and time zone variations. It also has tighter compliance and security requirements.

Offshore delivers maximum value for standardized testing of well-documented products through specialized, large teams. It optimizes costs while providing round-the-clock support for global clients.

Nearshore Delivery Model:

Nearshore relocates delivery to a neighboring country with similar language, culture, and compliance needs. The primary perks are:

• Proximity ensures easier collaboration through shorter distances and faster turnarounds than offshore.
• Shared time zones will permit some overlapping work hours daily for discussions.
• Regulatory familiarity will streamline compliance due to regional legal ecosystem understanding.

However, nearshore also has limitations. Costs are higher than in offshore locations. Infrastructure, processes, and talent pool maturity may lag behind hubs like India.

Nearshore suits projects requiring frequent collaboration and quick turnarounds while still delivering cost optimization through regional proximity. It is ideal for regulated applications and critical systems.

Customized Delivery Models:

Leading software testing companies design hybrid models blending the above to maximize benefits:

• Onshore-offshore right-shore delivery will leverage both local and global resources based on priorities.
• The cluster model maintains distributed, co-located onshore teams globally for seamless support.
• Dedicated centers house exclusively dedicated resources in offshore locations. 
• Co-shoring leverages the strengths of multiple nearshore and offshore centers based on phases.
• Managed services take complete responsibility for testing functions through consultancy-led governance.

This flexibility will ensure optimal delivery, quality, costs, and collaboration aligned with unique client and project needs in dynamic business environments.

Evaluating Model Suitability:

The pivotal factors to consider when opting for a delivery approach include:

• Nature, complexity, and industry of the application 
• Testing scope, types, priorities, and timelines
• Collaboration and communication needs
• Regulatory, security, and compliance mandates
• Available investment and optimization goals  
• Vendor expertise, processes, scalability, and compliance credentials

A balanced and thorough evaluation of these parameters helps identify the most suitable model or right-shored hybrid approach. It will boost the perks while mitigating risks.

Managed Testing Services Model:

Managed services involve a vendor taking complete responsibility for testing functions through consultancy-led governance and delivery. The pivotal aspects will include:

Test Strategy & Consulting: Vendors help define the optimal testing approach, RoI-focused charter, and SOW

Resource Planning & Management: Right-sizing teams, allocating experts, career growth, and retention

Process Standardization: Maturing in-house processes to CMMI, automating workflows, KPIs, and reporting  

Tool Augmentation: Procuring, customizing, and maintaining tools to maximize coverage and efficiency

Center of Excellence: Building reusable assets, frameworks, libraries, and training programs.

Continuous Improvement: Benchmarking, audits, feedback-driven enhancements, quality initiatives

This ensures testing is always aligned with business objectives through expert oversight and flexibility. Resources are leveraged optimally across projects.

Co-Shored Delivery Model:

Co-shoring leverages the strengths of multiple nearshore and offshore centers based on priorities:

Planning Phase: Onshore experts define strategy, charter, estimations, and quality benchmarks.

Design Phase: Nearshore centers collaborate on requirements, test cases, and automation blueprints. 

Development Phase: Offshore resources execute automated regression suites and integration testing.

Deployment Phase: Nearshore validates pre-production environments and user acceptance testing.

Post-Release Phase: Offshore centers perform maintenance testing, release management, and support.

This phased model maximizes collaboration, quick turnarounds, and quality through a right-shored approach optimized for the software development lifecycle.

Cluster Delivery Model:

The cluster model distributes co-located onshore teams globally for seamless support across regions.

Dedicated Expert Teams: Small groups of 5-10 resources located near client sites.

Center of Excellence: The central team provides tools, frameworks, training, and process governance. 

Streamlined Collaboration: Frequent interactions with clients and other teams through a hub-spoke model 

Quick Turnarounds: Nearby resources address issues immediately without time zone delays.

Follow-The-Sun Testing: Baton passing allows testing 24/7 through clustered time zone coverage.

This ensures consistent quality, localized support, and faster resolutions through globally distributed localized assets.

Hybrid Delivery Model:

Hybrid blends multiple models, leveraging their unique strengths based on evolving needs:

Pilot Phase: Onshore experts validate the strategy, and critical test cases are reviewed.

System Testing: Offshore centers perform extensive regression, integration, and API testing.

UAT Phase: Nearshore validates pre-production builds, user flows, and edge cases. 

Post-Launch Phase: Offshore centers perform maintenance testing and support incidents.

Regulated Modules: Onshore experts handle financial and healthcare components.

This flexibility optimizes delivery, quality, and costs at each stage through a customized blended approach.

Conclusion:

With distributed global development, a one-size-fits-all delivery is rarely optimal. Opting for the right model based on nuanced organizational needs delivers maximum testing value. India offers customized solutions balancing quality, costs, and collaboration in this dynamic digital era.
