Usually, however, this bias is weak enough to overcome, thus allowing ISM to be used for clearly expressing a wide range of scientific practices and views about science. If this means a rigid sequence of steps or an implication that all science is the same, there is no method. But with a broader definition, the answer is yes. Scientific methods are flexible, so a model of scientific methods should be flexible. Therefore, ISM does not try to define a single method for all science.
Scientists can begin at any point in a cycle.
ISM can also be used to describe and analyze the complexities of timing that involve overlapping and interconnected activities, iterative cycles within cycles, multiple branchings, and so on. But even though some patterns do exist in the sequencing of activities, ISM should be viewed, not as a rigorous flowchart of scientific activity, but as a roadmap that shows some possibilities for creative wandering.
