Abstract: In order to improve the understanding of the method of slices for the slope stability analysis, some important common issues are discussed in detail. These issues are: independent assumption equation numbers, different ways approaching slope stability solutions, importance of moment equilibrium equations, and failure slip surface shape.  The role of Pan's principle for slope stability analysis is also discussed.
