For the purposes <strong>of</strong> this review we take the most satisfactory evidence-based inquiry to be<br />

that which either:<br />

• Relates input to output, or action to effect in a way that gives some confidence that an<br />

effect has taken place in a defined situation <strong>and</strong> context. Such inquiry <strong>of</strong>ten has a<br />

quantitative <strong>and</strong> statistical element <strong>and</strong> a basis for believing that an effect has taken<br />

place.<br />

• Detailed observation based accounts <strong>of</strong> process as they unfold or are triggered by<br />

deliberate action, with regard to situation <strong>and</strong> context. Such inquiry will tend to be<br />

more qualitative, but may include quantitative <strong>and</strong> statistical elements to the extent to<br />

which the phenomena <strong>and</strong> processes described have a quantitative dimension.<br />

Each <strong>of</strong> these are taken to be <strong>of</strong> equal value, <strong>and</strong> the most satisfactory kind, <strong>of</strong> evidencebased<br />

research<br />

Less satisfactory but useful in the absence <strong>of</strong> anything better are:<br />

• Conclusions drawn from consensus amongst a group <strong>of</strong> people who can be regarded<br />

has having experience <strong>and</strong> expertise on the issue in question.<br />

Still occasionally useful after this are:<br />

• Arguments grounded in examples <strong>of</strong> events <strong>and</strong> phenomena to give some anchorage<br />

in ‘reality’ to the argument <strong>and</strong> analysis at least some points, or based on opinions<br />

that have some apparent basis in the experience <strong>of</strong> those expressing them.<br />

Beyond this, for the purposes <strong>of</strong> this review, is material outside the boundary <strong>of</strong> our<br />

pragmatic definition <strong>of</strong> evidence-based inquiry.<br />

Speculative material we divide into that which:<br />

• Has some internal logic, rigour <strong>and</strong> consistency, <strong>and</strong> theoretical coherence, perhaps<br />

drawing on theoretical propositions that have some evidence based justification<br />

elsewhere.<br />

• Material that is weak or defective in terms <strong>of</strong> these criteria.<br />

For the purposes <strong>of</strong> this <strong>of</strong> this review only material with a clear quantitative or qualitative<br />

evidence base, <strong>and</strong> rigorous speculative material making useful suggestions has been<br />

included.<br />

Weaknesses <strong>of</strong> methodology: one <strong>of</strong> the difficulties <strong>of</strong> demonstrating a link between<br />

management development <strong>and</strong> organisational performance lies in finding a strong<br />

methodology. <strong>Management</strong> development is not an area in which the preferred method <strong>of</strong><br />

‘hard’ science - the double blind r<strong>and</strong>omised controlled trial – can be used. Research is<br />

generally post hoc <strong>and</strong> researchers usually have no control over the intervening variables.<br />

<strong>The</strong> difficulties <strong>of</strong> finding adequate methodologies to study the effectiveness <strong>of</strong> management<br />

development programmes has meant that many studies rely mainly on a methodology based<br />

on self-report about the impact <strong>of</strong> the programme. Self-report – individuals saying that the<br />

programme has been useful, or that they <strong>and</strong> their organisation have benefited - is not the<br />
