How to read this

Every construct on the map is compared with every other by the meaning of its definitions, and the closest one is surfaced here. The nearest construct to synergy is coordination.

Hold this as a prompt, not a verdict. Two constructs sitting close in meaning is a reason to read them side by side and decide for yourself whether they are one idea under two names. It is not proof that they are. Compare the meanings in the Collider.

Corporate strategy and finance

the extra value a merger is expected to create, making the combined firm worth more than the two apart.

The extra economic value a merger is expected to create, so that the combined firm is worth more than the two firms apart: it is claimed through cost savings, revenue gains, market power, or cheaper financing, and it is the standard justification for paying a premium in an acquisition. Chatterjee's 1986 Types of synergy and economic value separated operational, financial, and collusive sources of this gain and studied their effect on the value of merging and rival firms. The referent is a projected change in firm value, priced in money and often overestimated, not a combined effect measured in a test tube, a field, or a moving limb.[1]

Unit
The value of the combined firm above the sum of the two standalone firms, in money
Recovery means
Not applicable
Measured by
Estimated from projected cost and revenue changes and from abnormal stock returns around the deal announcement

Pharmacology

two drugs given together producing a larger effect than the sum of their separate effects would predict.

The situation where two drugs given together produce a larger effect than the sum of their separate effects would predict, so the combination is more potent than simple addition: it is judged against an explicit reference model for what pure addition would look like. Chou's 2006 Theoretical basis, experimental design, and computerized simulation of synergism and antagonism in drug combination studies set out the combination index method and its dose-effect logic, building on Loewe additivity and the older Bliss independence idea. The referent is a measured departure from additivity in a biological assay, established by isobologram or index, not a merger's payoff, an ecosystem's response, or a pattern of muscle activity.[2]

Unit
The excess of a drug combination's effect over what additivity predicts, given by a combination index
Recovery means
Not applicable
Measured by
Quantified with isobologram analysis, Loewe additivity, Bliss independence, or the combination index across dose ratios

Ecology

two or more stressors together causing more harm to a population or ecosystem than the sum of their effects.

The case where two or more stressors acting on a population or ecosystem together cause more harm than the sum of their individual effects, so their joint impact is worse than adding them up: it is contrasted with additive and antagonistic interactions of the same stressors. Crain, Kroeker, and Halpern's 2008 Interactive and cumulative effects of multiple human stressors in marine systems reviewed many experiments and found synergistic interactions to be common. The referent is a super-additive ecological response to combined pressures, measured across whole systems, not a firm's value, a drug assay result, or a coordinated muscle group.[3]

Unit
The gap between the observed joint effect of stressors and their predicted additive effect on a biological response
Recovery means
Depends on the system: some communities recover once a stressor is removed, but synergistic damage can persist
Measured by
Assessed with factorial experiments and meta-analysis that compare the combined effect against an additive null

Motor neuroscience

a fixed group of muscles the nervous system activates together as one unit to build complex movements.

A fixed group of muscles that the nervous system activates together as a single coordinated unit, so that complex movements are built by combining a small number of these building blocks rather than controlling every muscle on its own. d'Avella, Saltiel, and Bizzi's 2003 Combinations of muscle synergies in the construction of a natural motor behavior extracted such shared activation patterns from recorded muscle activity and showed how their time-varying combination reconstructs natural movement. The referent is a low-dimensional pattern of muscle coordination in the body, found by decomposing activity data, not a financial gain, a drug interaction, or an ecological response.[4]

Unit
One shared activation pattern across muscles, a component extracted from many recorded muscles
Recovery means
Not applicable
Measured by
Recovered from electromyography by matrix decomposition such as non-negative matrix factorization into shared components
