I'm writing a proposal in which I describe a series of small projects/experiments. The projects start out small and basic, then the subsequent project builds on the results from the prior project. I need to convey the idea that the projects have been carefully selected to complement each other, and that the sequence in which they are executed is important. I'm sure there is a word or short phrase somewhere that describes this idea succinctly.
The sort of phrase in which this word would be used: "The new technique will be applied in a series of projects designed to blah blah blah." Or: "The new technique will be applied in sequential projects that rely on yada yada yada."
Here are some related words I've considered:
"Sequential", "successive": These are ok because they tell the reader that I am doing one project after another, but they don't convey the relationship between the projects.
"Progressive": Getting closer, but this word also can mean "revolutionary" or "modern" and sounds a bit weird in this context.
"Escalating": Has the right feel, but it's too intense, and doesn't denote a series of events.
Thanks for helping.
