Software Processes Some nuances about our software development processes New releases are made live in the shortest time Quick Feedback cycle We imbibe Agile development practices (from Scrum and XP) Some of our Beliefs - Processes evolve vs Processes are fixed and rigid Different strokes for different projects vs One size fits all Change is welcome vs A Release spec is final Small and faster iterations vs Large and longer releases Test-first Development vs Testing after Coding Integrate often and continuously vs Integrate at the end

Some nuances about our software development processes

New releases are made live in the shortest time

Quick Feedback cycle

We imbibe Agile development practices (from Scrum and XP)

Some of our Beliefs -

Processes evolve vs Processes are fixed and rigid

Different strokes for different projects vs One size fits all

Change is welcome vs A Release spec is final

Small and faster iterations vs Large and longer releases

Test-first Development vs Testing after Coding

Integrate often and continuously vs Integrate at the end
