Zero-defect methods aim to produce as defect-free software as possible before the software is built. Zero-defect methods grant the developer to deploy software directly from the build process to clients with great confidence. This website was created as a part of a Bachelor's Thesis by Pekka Leppäluoto and despite its grand name, it introduces methods and concepts that only scratch the surface of zero-defect programming.

Introduction

The advancements of technology have brought software closer and more accessible to us in our everyday life. Though technological advancement software is given increasingly major roles in performing tasks for different purposes and fields of our society. The pressure to fulfil and handle the required tasks of software is growing.

Software engineering sciences are relatively new engineering sciences and are still pursuing to find their place under the sun. Software projects are carried out by various methods resulting in various outcomes. A constant struggle against defects has been a prominent characteristic in many software implementations. Today's software engineering methods leave the removal of defects into a separate, inefficient phase called software testing.

There have been many new attempts to increase the reliability and quality of software from enhancing customer-developer communication to forming formal theoretical models of software and vefifying them. Some of the methods introduced here are based on concepts from the 14th century or the late 1960s. The basics of zero-defect methods are easy -- they just need to be revealed, and understood that there should be left no room for interpretation.

It needs to be also mentioned that software produced with zero-defect methods will have defects in it. This is a fact as long as the human factor is in the equation. Zero-defect is a goal that should be pursued by all parties involved in software business from the software supplier to the software customer.
