Managing stakeholders can help you to ensure that your projects succeed where others might fail.

What is a composite state in a UML state machine diagram?

A simple state is one which has no substructure. A state which has substates (nested states) is called a composite state. Substates may be nested to any level. A nested state machine may have at most one initial state and one final state. Substates are used to simplify complex flat state machines by showing that some states are only possible within a particular context (the enclosing state).

Develop DFD with Stepwise Refinement

One of the effective way to solve a complex problem is to break it down into simpler sub-problems. You start by breaking down the whole task into simpler parts. Step-by-step refinement is essentially a decomposition of the system to gain insight into the subsystems that make up the system, known as the top-down decomposition method.

Scatter Diagram Tutorial

A Scatter Plot (also known as a scatter Chart, and Correlation Plot) is a tool for analyzing the relationship between two variables, used to determine the degree of correlation between two variables. One variable is plotted on the horizontal axis and the other on the vertical axis. The pattern of their intersection points graphically displays the relational pattern. It is one of the Seven Basic Tools of Quality.

Fault Tree Diagram Tutorial

Fault Tree Diagram Tutorial

Fault tree analysis (FTA) is a top-down deductive fault analysis in which Boolean logic is used in conjunction with a series of low-level events to analyze the unexpected states of the system. This analysis method is primarily used in safety engineering and reliability engineering to understand how systems fail, determine the best way to reduce risk, and determine (or feel) the event rate of safety incidents or specific system-level (functional) failures.
