User Centered Design | Glossary

Definition:

User Centered design (UCD) is a process where designers, developers focuses on gaining deep understanding of the users. This is not only from interfaces and technology perspective but at each step keen attention is given for usability goals, context of the use, user characteristics, workflow of the product and usability testing with actual users.

This creates highly usable products which not only analyzes the way user consumes a product but also validates the behaviour of the user in real world. Tests conducted with or without actual users during requirements, pre-production and post production stages ensures development is user centric.

Below are the Principles that will ensure a User-centered design:

  • The design is based upon an explicit understanding of users, tasks and environments
  • Users are involved throughout design and development
  • The design is driven and refined by user-centered evaluation
  • UCD process is iterative
  • Designing the overall  user experience
  • The design team includes multidisciplinary skills and perspectives
  • This perspective of User Centered design increases product usefulness and usability.

Positive Testing | Glossary

Definition:
The basic functionality of Testing is carried out to find the defects in the code & enhance the quality of Software Application. Software Testing is process of Verification and Validation to check whether the Software Application is properly  functioning.

Testing of application can be done in two different ways, Positive testing and Negative testing.

Positive Testing is a testing process where the tester will check a set of values and validate, if the application behaves as expected with its provided inputs. Such testing is to be carried out keeping positive point of view and only execute the positive scenario.

The main intention of the positive testing is to check whether the Software Application is  showing any errors when it is not supposed to and not showing error when it is supposed to. The Positive Testing always tries to prove that a given product and project meets the requirements and specifications.
