Quality became a strategic differential for IT developing companies. Based on this fact,  Zero-Defect works with specialized companies in software development aiming at testing and homologating projects that reach the final delivery in perfect using conditions. By uniting expertises of two specialist teams, easiness and speed in correcting errors makes costs reduce. Besides, the project will present the certified quality of testing and validation by a specialized and recognized company in the market.   

 

System Approval
System approval aims at ensuring the correct software operation based on the expectations of the contracting company.
Common tests: Functional test, usability test

System Convergence Validation
With the evolution of technologies, many organizations modify the programming language of systems, aiming at better performance and use. The objective of Zero-Defect is ensuring this platform or technology change does not impact on business rules and also on the use of the system by the target audience.  
Common tests: Functional test, environment test, performance test

Web Systems Validation
Ease in menu navigation, layout coherence, business rule and the performance of the system when used by a high number of users are analyzed.
Common tests:Functional test, usability test, performance test

Validation of Systems Migration
Development of a process of validation and verification of systems and environments to be migrated by the company with no impacts or loss of data.
Common tests: Functional test, environment test

Validation of Systems Integration
Many organizations find it difficult to integrate systems from different platforms and technologies. The validation of systems integration aims at evaluating if communication and data switched among all these technologies and platforms are running smoothly.
Common tests: Functional test, environment test

Validation of Systems in Evolving Maintenance
Zero-Defect creates a staff exclusively assembled to assist the testing needs of your company. This procedure reduces costs, optimizes time to market and ensures a professional and qualified testing process.
Common tests: Functional test, usability test, environment test, security test, performance test

Validation of System Performance
It is the monitoring of the performance time of an application routine through specialized tools that carry out the performance evaluation of the complete system architecture.
Common tests: Functional test, performance test

Test Automation
When it is necessary either to carry out a task with repetitive tasks or to simulate access of several users in a system, the process of Test Automation is used. This process has two main focuses: Functionality / Interface Tests and Performance Tests (load, stress and scalability). For the Functionality / Interface Tests the process of Automation is recommended to create a relatively high mass of data and simulate repetitive sceneries in order to retest them in a faster way. For the Performance Tests the process of Test Automation creates virtual users based on specific tools in order to simulate access to the system with the objective of evaluating response time for an excessive quantity of users.
Common tests: Functional test, performance test, environment test

Independent Audit and Compliance to ISO/IEC Norms

ISO/IEC norms define a group of patterns about specific guidances. Zero-Defect uses these patterns to inspect artifacts and evidences in the focus selected by the customer (process, project or policies, for example), ensuring they comply to ISO/IEC. After these inspections, a report of non-compliance and adherence to the pattern is issued to the customer in order to obtain a clear and objective view of the action plan for each exposed item. Zero-Defect works with the following ISOs:
ISO 1779 / 27000: Security Techniques
ISO 14598: Evaluation of product software
ISO 9126: Product quality
ISO 12207 - Process of software life cycle
ISO 12119 - Quality test and requirements
