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:
“To live a better life,—this surely can be done.”
—Henry David Thoreau (1817–1862)
“Reminiscences, even extensive ones, do not always amount to an autobiography.... For autobiography has to do with time, with sequence and what makes up the continuous flow of life. Here, I am talking of a space, of moments and discontinuities. For even if months and years appear here, it is in the form they have in the moment of recollection. This strange form—it may be called fleeting or eternal—is in neither case the stuff that life is made of.”
—Walter Benjamin (1892–1940)
“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)
