Subclaims

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q2 i? Based on the authors' synthesis of prior research, the three most common reasons implementation projects fail are simplistic planning, lack of adaptation, and poor teamwork, and all three can arise at key points throughout the process rather than strictly in sequence. → Allen 2026

q2 · i? · review · r2

A narrative synthesis of prior implementation research (cited sources 10, 20-21) in which the authors identify the three primary failure modes; the article reports no new empirical data or effect sizes for this claim. The authors note counterintuitively that "all three of these failure mechanisms can arise at key points throughout the process."

"Based on our synthesis of prior research [10,20-21], we identify simplistic planning, lack of adaptation, and poor teamwork to be the most common reasons that implementation projects fail."
