Core Idea

A best practice is not just a commonly recommended action. It is the output of a reusable selection-and-update operation: define an outcome and context, identify serious alternative practices, compare them with evidence against explicit criteria, provisionally designate the strongest current option as the default, test whether the evidence transfers to the intended setting, and withdraw or revise the designation when conditions or evidence change.

The word best is therefore scoped, comparative, and defeasible. It means “best supported among the relevant alternatives, for this outcome, population, time, resource envelope, risk tolerance, and evidence base”—not “universally optimal.” Bretschneider, Marc-Aurele, and Wu make comparison, an action, and a link between that action and a desired outcome central to rigorous best-practices research.

How would you explain it like I'm…

Best Way So Far

A best practice is the way of doing a job that has worked best so far, when people compared it with other ways. Everyone starts with that way. But if someone finds a better way, or things change, the best practice changes too.

The Tested Go-To Method

A best practice is a way of doing something that people have compared with other ways and found to work best, so far and for a certain kind of situation. It has to be an actual method you can teach and repeat, not just "be like the winning team." "Best" doesn't mean best forever or best everywhere: what works best for a big hospital might not work for a small clinic. It's a starting point that says "do it this way unless there's a good reason not to." And when new evidence shows something better, the best practice gets updated.

Evidence-Based Default Method

A best practice is more than a popular recommendation; it's the result of a process: define the outcome and the setting, gather the serious alternatives, compare them using evidence and clear criteria, pick the strongest as the default, check whether the evidence applies where you want to use it, and update when things change. 'Best' is limited in scope and open to revision: best supported, among the options considered, for a particular goal, group, time, budget, and level of risk. 'Practice' matters too: it must be a repeatable action that can be described, taught, and monitored, not just an admired organization or a slogan. Copying a top performer only works if you figure out which of its actions actually caused the success and whether they'll work in your context. Finally, a best practice is a default, not a rule you must follow; laws or protocols may adopt one, but that authority is added on top.

 

A best practice is the output of a reusable selection-and-update procedure: specify an outcome and context, identify serious alternative practices, compare them against explicit criteria using evidence, provisionally designate the strongest as the default, test whether the evidence transfers to the target setting, and revise or withdraw the designation when evidence or conditions change. "Best" is therefore scoped to an outcome, population, time, resource envelope, risk tolerance, and evidence base; comparative among the relevant alternatives; and defeasible. Rigorous best-practice research needs a comparison, a specified action, and a demonstrated link between that action and the desired outcome, and the comparability and coverage of cases limit any claim of superiority, so the best case in a sample is not automatically a best practice outside it. "Practice" requires a repeatable, specifiable, teachable, monitorable course of action; a high-performing organization is evidence worth investigating, but its causally effective practice must be identified before it can be transferred, which Bardach calls the extrapolation problem. Finally, the designation is a default, not a mandate: it cuts repeated decision costs by saying "start here absent a reason to depart," while keeping documented exceptions and a revision path. Laws, clinical standards of care, or protocols may incorporate a best practice, but enforceability is an added institutional property.

Tensions in Practice

• Stable defaults in tension with learning

Broad Use

Public administration and policy. Agencies routinely look to peer jurisdictions for working methods. Rigorous best-practice work does not copy the most celebrated program. It defines the target problem, recovers the source practice's causal design, compares relevant alternatives, and solves Bardach's extrapolation problem before adaptation. Bretschneider and colleagues add the need for comparable cases, disclosed outcomes, and limits on generalization.

Clinical recommendations. Trustworthy clinical practice guidelines translate systematic evidence into recommendations relevant to patient decisions. The Institute of Medicine requires systematic review, evidence foundations, assessment of benefits and harms of alternatives, transparent articulation, external review, and updating.

Clarity

The prime replaces the bare superlative with a complete claim:

For outcome O, among alternatives P, in context C, current evidence E evaluated by criteria K supports practice p* as the default until trigger R requires review.

This sentence exposes five frequent omissions. Without O, the alternatives may optimize different ends. Without P, “best” has no comparison class. Without C, transfer becomes universalization. Without K, trade-offs remain political or technical choices disguised as fact.

Manages Complexity

Best Practice compresses repeated multi-criteria decisions. Once a comparison has been performed and its scope recorded, later actors need not reconstruct every alternative from scratch. They can adopt the current default, verify that the applicability conditions hold, and spend attention on exceptions. The designation is therefore a cached decision with provenance.

Abstract Reasoning

The central inference is comparative and conditional, not categorical. Evidence supports p* over alternatives under C and K; it does not entail p* independent of context. Transfer is a second inference: if the causal features and implementation supports that made p* work in source contexts are present or can be recreated in target context C', then p* is a candidate default in C'. Bardach's extrapolation analysis exists because this second inference is not automatic.

Knowledge Transfer

Transfer proceeds through six artifacts:

1. Practice specification: the repeatable actions and minimum fidelity conditions.
2. Outcome model: the desired effects, unacceptable harms, and plausible causal mechanism.
3. Source context: population, resources, capabilities, scale, incentives, and constraints under which evidence was produced.
4. Target-context comparison: which source conditions match, differ, or can be adapted.
5. Local trial or validation: evidence that the adapted practice works for intended use.
6. Maintenance rule: metrics, owner, review interval, and triggers for revision.
