“Application testing services” is a comprehensive term for the verification and validation services that support quality control and quality assurance (QA) of clients’ applications. Verification assesses whether a product/application or service complies with regulations, requirements, specifications or enforced constraints. Validation typically involves engagement with external customers to confirm suitability and acceptance. Infrastructure testing services, mobile device testing and software testing tools created for the market by independent software vendors (ISVs) are not included in this definition.
Gartner defines cloud ERP services as services provided by third-party systems integrators to assess needs, implement solutions and evolve platforms that are transforming their back-office systems via the implementation of cloud-based ERP solutions. A cloud ERP solution is a set of applications (SaaS) that are sold/marketed as integrated products to support organizations. These integrated products include financial management (FM) functionality, human capital management (HCM), supply chain management (SCM) and other administrative ERP functionality.
Gartner defines custom software development (CSD) services as those that develop software in rapid increments and iterate custom applications and software products to meet an organization’s unique business needs. CSD services entail gathering business requirements and coding applications from inception, building applications on a platform as a service (PaaS), or assembling applications from existing web services or other reusable pieces of code. Services marketed as “software product engineering” or “digital product development” are likely to be examples of the category Gartner defines as CSD services.
