Live Sequence Charts
David Harel thinks that MSC still has several shortcomings such as:
- MSC propose a weak partial ordering semantics that makes it impossible to capture some behavioral requirements,
- The relationship between the MSC requirements and the executable specification is not clear.
To address what he sees as weaknesses in the MSC model, David Harel proposed an extension on the MSC standard called LSC (Live Sequence Charts).

Famous quotes containing the words live, sequence and/or charts:
“For my part, I would rather look toward Rutland than Jerusalem. Rutland,—modern town,—land of ruts,—trivial and worn,—not too sacred,—with no holy sepulchre, but profane green fields and dusty roads, and opportunity to live as holy a life as you can, where the sacredness, if there is any, is all in yourself and not in the place.”
—Henry David Thoreau (1817–1862)
“We have defined a story as a narrative of events arranged in their time-sequence. A plot is also a narrative of events, the emphasis falling on causality. “The king died and then the queen died” is a story. “The king died, and then the queen died of grief” is a plot. The time sequence is preserved, but the sense of causality overshadows it.”
—E.M. (Edward Morgan)
“There’s one basic rule you should remember about development charts that will save you countless hours of worry.... The fact that a child passes through a particular developmental stage is always more important than the age of that child when he or she does it. In the long run, it really doesn’t matter whether you learn to walk at ten months or fifteen months—as long as you learn how to walk.”
—Lawrence Kutner (20th century)
