STEM Way represents the disciplined way of doing activities in STEM 2.0. These activities (or steps) are grouped in disciplines that are used in the THREE phases.

The first phase BASELINING is primarily about the ensuring that we understand the product in terms of features, attributes, technology and the types of the defects that could cause “dirtiness”. The two key disciplines that help accomplish this in Baselining phase are Business Value Understanding and Defect Hypothesis.

The second phase FORMULATION is about ensuring that we formulate the strategy, plan, test cases, scripts and measurements to help clearly formulate the plan of action. This consists of four disciplines – Strategy & Planning, Test design, Tooling and Visibility.

The third phase EVALUATION is about evaluating the software to ensure that final released software is clean enough and fit for release/deployment. This consists of two key disciplines – Execution & Reporting and Management.

The goal of the test engineering method STEM 2.0 is to produce clean software. This goal is broken into phase wise goals and subsequently into discipline wise goals. The figure below shows the discipline wise goals.

A core set of scientific concepts powers each step in the various disciplines of STEM ensuring that each step is done in a scientific manner.
