Structural Power: Intraorganizational of Sources Synthesis1 A Theoretical W. GRAHAM ASTLEY PARAMJIT S. SACHDEVA University of Pennsylvania Research on organizationalpower has become overly fragmented; a multitudeof differentsourcesof power have beenidentified.Consequentpower relationsis difficult to ly, an overallpicture of intraorganizational obtain. In this paper, three structuralsources of power-hierarchical authority, resourcecontrol, and networkcentrality-are integratedin a power is theoreticalsynthesis. Thecomplexnatureof intraorganizational revealedin the interactions,tensions,and conflictsamongthe threesources of power. Everysocial act is an exerciseof power, everysocial relationshipis a power equation, and every social groupor systemis an organizationof power.Accordingly, it is possibleto transposeany systemof social relationshipsinto termsof potentialor activepower. (Hawley, 1963, p. 422). As the above indicates, it is possible to interpretevery instance of interaction and every social relationship as involving an exercise of power, because actors clearly affect one another all the time they are interacting. But this very pervasivenesstends to make the concept of power elusive and redundant, for it begins to have no meaning apart from the ideas of social interaction and organization. The problems associated with defining power consequently are well known (Wrong, 1968) and have led March (1966) to conclude pessimistically that the concept is of little analytical utility, because the apparent ease with which it can be applied to multiple different types of empirical phenomena tends to make statements about power rather empty or tautological. Despite this controversial ahd problematic status of the concept of power, its use is retained in this paper as a general orienting concept possessing at least one basic connotation: power is viewed as a capacity of social actors to overcome resistance on the part of other social actors in order to achieve desired objectives or results (Dahl, 1957). Beyond this general notion, however, a more precise definition of the concept is not offered here because, following Lukes (1974), power is regarded as being what Gallie (1955-1956) has termed an "essentially contested concept." That is, power is viewed as one of those concepts that "inevitably involves endless disputes about (its) proper use on the part of (its) users" (Gallie, 1955, p. 169). Part of the problem here is that power takes on a very precise meaning only when the analysis is applied to a particularsituation, and such application depends on the purposes of the particularanalyst concerned. As Pfeffer (1981) states, power is "context specific." Given this, what the present paper hopes to offer is a context-specific analysis of power that is particularly applicable to social relationships within formal organizations. With this same general aim in mind, some social scientists have begun to focus on a number of dimensions of power that are grounded in specific social and organizational contexts. Thus, power has been 'The preparation of this manuscript was supported by funds from the Center for the Study of Organizational Innovation, University of Pennsylvania. The authors would like to thank Charles Fombrun and Andrew Van de Ven for their helpful comments on an earlier draft of this paper, which was presented at the 41 st Annual Meeting of the Academy of Management, Organization and Management Theory Division, San Diego, 1981. 104 This content downloaded from 62.122.79.39 on Fri, 9 May 2014 20:36:24 PM All use subject to JSTOR Terms and Conditions tions and have overlookedthe potentialtensionbetweendifferentfacetsof power(Bacharach& Lawler, 1980, p. 31). To remedy this situation, this paper analyzes intraorganizational power as the joint product of three sources of power: the official authority vested in hierarchical positions (hierarchical authority); the capacity for obtaining resources from the environment and controlling the supply of these resources to others through processes of exchange (resource control); and the centrality of location within the organization's network of workflow linkages (network centrality). Each of these is described as a "structural" source of power in the sense that it reflects the properties of the organization as a social system rather than being a product of the psychology or social psychology of particular individuals within the organization. Recent research is synthesized, and tentative hypotheses regardingthe intersection of the three power sources are examined. The objective is to construct an overall view of intraorganizational power that reconstitutes power as a global phenomenon and still takes into account its analytical dissection into discrete and qualitativelydifferent subtypes. dissected into different "bases" (French & Raven, 1959; Peabody, 1962); "kinds" (Etzioni, 1961); "types (Olsen, 1978); "sources" (Bacharach & Lawler, 1980; Pfeffer, 1981); and so on. Although moving in a direction that lends the concept greater empirical precision, these authors have introduced another problem. The proliferation of multiple subtypes of power has tended to stimulate research efforts dealing primarily with just one aspect of the overall concept in isolation from its other aspects, with the result that researchers, unfortunately, often have lost sight of "power" as a global phenomenon. For example, Weber's (1947) influential analysis of organizational power tended to focus on its formal aspects, tying it more or less exclusively to hierarchical authority relations. More contemporary accounts, on the other hand, tend to pay rather scant attention to the nature and source of efficacy of hierarchical authority (Mintzberg, 1983; Pfeffer, 1981), or they ignore its existence altogether (Hickson, Hinings, Lee, Schneck, & Pennings, 1971). Thus, power often is analyzed as if it is grounded solely in dependence relationships (Emerson, 1962). It is treated as an emergent phenomenon that "has been typically formulated as a variance from formal structure" (Clegg & Dunkerly, 1980, p. 458). Moreover, two major variants of nonformal, or emergent, power theories have come to the fore in contemporary theory. One explains power by reference to an actor's capacity to control the resources on which others depend (Pfeffer & Salancik, 1978). The other explains power by reference to an actor's locational centrality within a network of workflow relations (Tichy & Fombrun, 1979). At least three major approaches to the analysis of organizational power remain. Although they deal with highly interrelated phenomena, they have developed mostly independently of one another. In consequence, research on intraorganizational power has become overly fragmented. Too often the differentiated aspects of power are analyzed as if they are detached from each other and unrelated. Except for a few rare exceptions-for example, Bacharach and Aiken, (1976); Drake and Mitchell (1977); and Grimes (1978)- little attempt has been made at specifying the conditions under which one source of power becomes more salient than another. And little attention has been focused on the identification of interactions between sources of power. Comparativeorganizationalstudies... have failedto recognizethe multidirectionalnatureof powerrela- Three Sources of Power Hierarchical Authority So much emphasis has been laid on Emerson's (1962) explanation of power as a dependence-generated phenomenon that power and dependence are treated almost as synonyms, and it has become difficult to talk of power without implying that it is grounded in dependence. Focusing on the dependencies that are generated by task allocations in the division of labor, many contemporary theorists have thereby emphasized "functional" sources of power at the expense of "formal" sources of power (Peabody, 1962). However, the popularity of power-dependence theory should not allow one to overlook the long-standing central importance of hierarchical authority, a concept that is not based primarily on the analysis of dependence (Blau & Schoenherr, 1971; Fayol, 1949; Gouldner, 1954; Gulick & Urwick, 1937; Mooney & Reiley, 1939; Pugh, Hickson, Hinings, & Turner, 1968). The interpretation of power in terms of authority relations, on which all of these latter studies focus, is grounded in the conception of power as something that inheres in official positions. Power is viewed as the product of formal decree. Subordinates obey superiors not so much because they are dependent on 105 This content downloaded from 62.122.79.39 on Fri, 9 May 2014 20:36:24 PM All use subject to JSTOR Terms and Conditions tion must cope; consequently,the capacityfor dealing with such uncertaintycan be regarded as a valuableresource(Pfeffer, 1981).It is for this reason that Pondy (1977) views the resource-dependence perspectiveand Hicksonet al.'s (1971)"uncertainty coping" perspectiveas basically variants on each other. In this respect, for example, Woodward (1965),Lawrenceand Lorsch(1967),and Hambrick (1981)detailedhow differentindustryenvironments presentorganizationswithdifferentsourcesof critical uncertainty,so thatparticularsubunitsbecomedominantwithinparticularindustries,as the task of scanningthe environmenttendsto shift fromthe domain of one functionalarea to that of another. the latter,but becausetheybelievethatthe latterhave a rightto exercisepowerby virtueof theirposition. Sheer incumbency in office provides sufficient grounds for the superiorto expect obedience. The superior'sright to issue commandsis enactedby a legitimized procedure that is considered by both superiorand subordinateas correct.Thus, authority requiresa degreeof obedienceas an end in itself; obedienceis due a superiormorebecauseof institutionalizedprivilegethanbecauseit is instrumentalin fulfillingthe dependentsubordinate'sneeds.Formal prerogativelies at the heart of the hierarchicaldifferentiationof power. ResourceControl Network Centrality The notion that poweris derivedfrom the ability to controlthe supplyof resourcesto othershas been emphasizedin the work of Yuchtmanand Seashore (1967), White (1974), Mindlinand Aldrich (1975), and Pfeffer and Salancik(1978). Nord (1980) has pointed out the respectsin which these "resourcedependenceperspectives"relyheavilyon underlying "exchangetheory" concepts(Blau, 1964;Emerson, 1962;Homans,1961;Thibaut& Kelley,1959).Thus, organizationalsubunitssupplyresourcesto othersin exchangefor a returnof resourcesupon whichthey are dependent;and asymmetryin the dependencies that underliesuch exchangesexplainsasymmetryin power betweenthe actors involved. The perspectiveoutlinedhere links this approach to the notion that resourcesultimatelyare derived fromthe environment.It contendsthatorganizations are open social systemsthat requirea supplyof resourcesfromthe environmentin orderto sustaintheir operations.The resourcesthat areobtainedin transactions with the environmentvary in terms of how difficult they are to secure and in terms of how criticalthey are to the organization'sfunctioning. Thoseorganizationalactorsthat obtainthe most critical and difficult to secureresourcesconsequently acquirepowerbecauseof the dependenciesthat are generated.For example,Salancikand Pfeffer (1974) revealedthat the ability of a universitydepartment to secureoutsidegrantsand contractswas relatedto its power;and Aldrichand Herker(1977), Whetten (1978),andSpekman(1979)eachhavesuggestedthat boundaryspanningsubunitsderivepowerfromtheir capacity to obtain information directly from the environment. Further,the environmentcan be viewedas a major source of uncertaintywith which the organiza- Theworkof complexorganizationstypicallyis segmentedinto discretepositionsthat are differentiated both verticallyby hierarchicalleveland horizontally by divisionor department.Thesedifferentiatedpositions arereintegratedthroughinterconnecting workflows that form a relativelystable networkof patternedinteractions.Tichyand Fombrun(1979)have arguedthat organizationalpower relationshipscan be analyzedprofitablyby referenceto this network of interactions.To the extentthat actorsare located at tightly coupled interconnectednodes in the network, they gain power becausetheir immersionin multipleinterdependencies makesthem functionally indispensable(Dubin, 1957; Hickson et al., 1971; Mechanic, 1962; Thompson, 1956; Woodward, 1965). By being centrallylocated, they act as conduitsfor integratingthe discretefunctionalcontributions of others who are not directlyinterconnected (Freeman,1979;Freeman,Roeder, & Mulholland, 1980). Network centralitycan be regardedas an additional sourceof intraorganizational powerover and above an actor's ability to generate dependencies throughresourceexchange.Such poweris attached to an actor's position in the network rather than derivedfrom a control of resourceswithinany particulardyadicrelationship.Of course, it is truethat degreeof access to multipleresourceflows will affect a subunit's ability to generate dependencies throughdyadicresourceexchange,but this overlappingdoes not erasethe analyticaldistinctionbetween the two sources of power. In this vein, Emerson (1976)refersto structuralpropertiesof location,such as networkcentrality,in termsof theircapacityfor 106 This content downloaded from 62.122.79.39 on Fri, 9 May 2014 20:36:24 PM All use subject to JSTOR Terms and Conditions of powerempiricallyinteresting.For example,Lehman's (1975) findings suggest that not only is the "distributionof resourcecontrol" important,but also importantis the "distributionof responsibility for decisionmaking." Similarly,Astley (1978)and Hambrick (1981) report that hierarchicallevelaccounts for largeproportionsof variancein decision makingpowerafter the effects of functionalexpertise andinterdependence areheldconstant.Gouldner (1954)has even utilizedthe distinctionbetweenformal and expertpower to posit the existenceof two types of bureaucracy:the "representativebureaucracy," which parallels Offe's "task-status continuous organization";and the "punishment-centered bureaucracy,"which parallelsOffe's "taskstatus discontinuousorganization."In Gouldner's study,moreover,it is particularlyinterestingthatthe representativebureaucracyis characterizedby an absenceof conflict,whereasthe punishment-centered bureaucracyis conflict-riddenbecauseof the tension producedby a lackof correspondence amongthe differentsourcesof power. This is the same sourceof tension that typicallyis highlightedby analysesof bureaucratic-professional conflict (Benson, 1973). creating "structural dependence" as opposed to dependence within a two-party exchange relation. Thuspowerderivesnot only fromresourcedependencies withinspecificexchangerelations,but also has a structuralcomponent,namelythe positionor location of theactorwithinthe exchangenetwork(Cook, 1977, p. 72). Pairwise Interactions Hierarchical authority, resource control, and network centrality appear together in organizational reality in interdependent configurations. Pairwise interactions among the three power sources pinpoint, systematically, instances in which they are mutually reinforcing, in which one dominated over another, in which tension is produced between them, and so on. HierarchicalAuthorityVersusResourceControl Although Weber (1947) recognizedthat hierarchicalpowerwas basedon formalauthority,he also understoodthat formal authoritywas substantially reinforced by the superior's ability to control resourcesupon whichthe subordinatedepends.This is reflected in what Gouldner has described as Weber's "biforked conception of bureaucracyas based on expertiseand on authoritariandiscipline" (1954, p. 219). That is, Weberassertedthat bureaucracyauthoritywas basednot only on formaldecree, Resource Control Versus Network Centrality Because the network analysis of organizations is still in its infancy (Fombrun, 1982; Tichy & Fom- but also on the superior's functional contributions of knowledge and expertise. One could say that Weber saw two sources of power stemming from the overall "rational-legal" legitimation of authority: authority based on incumbency in office (its "legal" component), and authority based on functional expertise (its "rational" component). Unfortunately, Weber's coupling of "rational" brun, 1979),thereis littleempiricalresearchdealing withthe interactionof resourcecontroland network centralityas sources of intraorganizationalpower. Thepresentauthorsareawareof only one study,that by Hinings,Hickson,Pennings,and Schneck(1974), that attemptsto look at this interaction.Even this studydid not self-consciouslyspellout the qualitative differencebetweenresourcecontrolandnetworkcentrality;it preferred,instead,to referto both of these simply as "strategiccontingencies."However, the study did succeedin comparingthe relativeeffects on subunit power of "coping with uncertainty" (which, as has been argued earlier, as a form of resourcecontrol)and "pervasiveness," definedas the extentto whicha positionis centrallyinterconnected to other positions. The authorsfound that possessionof each source of powerwas necessary,but not alone sufficient,for a subunitto gain a control of "strategiccontingencies" and therebymakeitself the dominantsubunit within the organization.Subunitsthat rankedhigh with "legal" impliesthat the institutionalizationof formalauthorityin a hierarchicaloffice alwaystends to correspondto the importanceof its functional role. Much of the time, however, such correspondence will be far less than perfect. Offe (1978) characterizesthis situation as "task-statusdiscontinuous organization" in contrast to "task-status continuous organization," in which formal authority and functional expertise do correspond; and he contends that the former is becoming increasingly prevalentin contemporarysociety. A numberof studieshave, in fact, indicatedthat formalauthorityand functionalexpertisedo not always coexist, and it is this that makesthe differentiation of hierarchicalauthorityas a discretesource on both coping with uncertainty and pervasiveness wereableto amassgreaterpowerthanweresubunits 107 This content downloaded from 62.122.79.39 on Fri, 9 May 2014 20:36:24 PM All use subject to JSTOR Terms and Conditions that ranked high on only one of these factors. Moreover, a regression analysis pointed to interactive effects between the two variables, indicating that it is important to analyze the two power sources within a single theoretical framework. some way by the presence or absence of the third source of power. Consider, first, the relationship between resource control and hierarchical authority. Parsons (1960) and Thompson (1967) have suggested the existence of a positive relationship between these two sources of power. Differentiating among three organizational functions-"technical," "managerial," and "institutional"-Thompson (1967) states that the technical function is mostly closed to the environment (closed off in the technical core); that the institutional function is largely responsible for articulating the organization's rights to command outside resources and is thus mostly open to the environment; and that the managerial function, because it procures outside resources for internal use in the technical core, is intermediate with respect to environmental openness. At the same time, these functions are located at "three distinct levels of responsibility and control" (Thompson, 1967, p. 10), which implies a positive relationship between hierarchical authority and resource control. Despite this, however, it seems clear that some control of environmental resources typically is also available at lower hierarchical levels, in which case the two power sources would be inverselyrelated. The empirical appearance of such a negative association appears best exemplified by the typical customer relations department of an industrialorganization, which normally would have little formal authority but would perform a great deal of boundary spanning activity and be responsible for the control and mediation of resources in the form of information about customers. It is suggested here that the direction of the relationship between resource control and hierarchical level in any particular organizational situation typically is also related to a subunit's score for the third source of power: network centrality. Thus, the closer a subunit is to the apex of the hierarchy, the more likely it will be centrally located in the organization's workflow in the sense that it typically will perform a centralized coordinating role in channeling the flow of environmentallyderived resources to multiple other subunits. In this situation its contacts with the environment tend to be critical, because it is located in a key position for safeguarding the continued functioning of units throughout the organization. It therefore is necessary to match its functional importance with formal authority to ensure that its performance is successfully undertaken. On the other hand, for subunits such as customer relations departments, which are not so centrally connected to multi- Network Centrality Versus Hierarchical Authority A major limitation of the Hinings et al. (1974) study was that its sample of subunits was drawn from the same level of hierarchy, so that pervasiveness, as an operationalization of network centrality, was correspondingly allowed only to vary in a horizontal dimension, and not vertically across levels. This limitation, however, was overcome by Tichy and Fombrun's (1979) analysis of interaction and influence data in three organizations. These authors make a distinction between "prescribed" and "emergent" networks. Prescribed networks are operationalized as aspects of "formal structure"they were "derived from organization charts" and were based on the hierarchical differentiation of "formal status." In other words, Tichy and Fombrun's prescribed network is a surrogate for what is referred to here as the hierarchy of authority. Emergent networks, on the other hand, were operationalized by sociometric measures of interaction generated by "work matters," and thus correspond to the network of workflow interaction. Prescribed and emergent networks were seen to be interdependent: Metaphorically, we assume that the prescribed organization provides the pegs upon which the emergentnetworkshang. Variationsin these pegs, therefore, alter the form of the emergentnetwork (Tichy& Fombrun, 1979, p. 929). However, with regard to this hypothesized correspondence between prescribedstructureand emergent network, the analysis found that the three organizations studied were quite different. In two of the organizations, which were described as "mechanistic," a reasonably high degree of "fit" existed between prescribedstructureand emergent network, indicating that hierarchicalauthority was reinforced by network centrality. On the other hand, in the third organization studied, described as "organic," the degree of "fit" was zero, indicating that the two sources of power varied independently. Again, this indicates the possibility of tension between different facets of organizational power, and it highlights the need for systematic investigation of such divergences. Three-Way Interactions It is contended that the relationship between each of the pairs discussed above typically is mediated in 108 This content downloaded from 62.122.79.39 on Fri, 9 May 2014 20:36:24 PM All use subject to JSTOR Terms and Conditions Figure 1 Network Centralityand Resource Control across TechnicalCore and BoundarySpanning Units ple units throughout the organization, responsibility for the procurement of environmental resources can be delegated to their lower hierarchical level because the immediate effects of any unsuccessful performance are restricted to a localized area. This interpretation is consonant with Hambrick's (1981) interpretation of the finding that "general managers" are more powerful than "external relations executives." Both categories of managers spanned organizational boundaries. General managers performed the organization's institutional function by "formulating and implementing overall policy; overall goal setting; [and] reporting to the board of trustees" (1981, p. 273). External relations executives were concerned with "public relations, fund raising, governmental relations, etc." (1981, p. 273). General managers naturally tended to be located at higher levels than did external relations executives, but even after controlling for hierarchical level, the former were much more powerful than the latter. Hambrick suggests, therefore, that "centrality" acted as an additional critical factor because general managers, "who typically span and integrate a variety of functions, have high centrality and, hence, high power" (1981, p. 267); and external relations executives, who "are not directly involved in the mainstream tasks, have low centrality and low power" (1981, p. 267). Consider the relationship between resource control and network centrality. This relationship also is mediated by the third source of power-in this case, hierarchical authority. At lower levels, a clear differentiation typically emerges between the technical core and boundary spanning units, which buffer the technical core from direct contact with the environment. One consequence of this differentiation is that boundary spanners, with direct access to the environment, exercise dominance in the form of resource control over the technical core positions, which are linked only indirectly to the environment. On the other hand, because boundary spanning units are located in a peripheral position, they typically have less workflow connections with other units than does the technical core, which is buffered by all of the boundary spanning units simultaneously. Thus, at lower hierarchical levels there is likely to be an inverse relationship between resource control and network centrality, as Figure 1 suggests. At upper levels of the hierarchy, however, there is no similar differentiation between boundary spanning and technical core subunits; thus, the same inverse relationship does not hold. Part of the reason for this is obvious. Decreasing Resource Control/ < A, ~~Centrality - Boundary Spanning Units Fewer people are located at higher than at lower levels, so there is less opportunity for differentiation to emerge. However, there also are additional factors to be considered, factors that are related to the kind of work that is performed at upper and lower levels. In this respect, a consideration of the differences between administrative and nonadministrative work is helpful. It is at the lower levels of the hierarchy that organizations perform their directly productive work in the "primary workflow" (Rice, 1958). This is where organizations introduce horizontal differentiation in order to create homogeneous duties within specialized subunits (Blau & Schoenherr, 1971). In other words, at lower hierarchical levels, the task of resource acquisition becomes specialized in boundary subunits, whereas the intricate technological interdependencies that enhance efficiency become specialized in the technical core subunits, where they can be sheltered from environmental intrusion. Specialization thus gives subunits highly specific functions and restricts their acquisition of power to a single source. Consequently, if a subunit controls resources because of its location at the boundary, it does not also gain centrality from its immersion within the technical core, and vice versa. This proposition is consonant with Thompson's contention that organizational power structures are adjusted in response to two sources of change: "internally from technological developments, and externally based on changes in task-environment elements" (1967. p. 129). Technology, in other words, 109 This content downloaded from 62.122.79.39 on Fri, 9 May 2014 20:36:24 PM All use subject to JSTOR Terms and Conditions 2(a) and Figure 2(b), representedby the arrows, would completelyalter the power situation. As the source of all resourcesin the network, Position A clearlywouldhavegreatestpowerin Figure2(a), but wouldbe a dependentrecipientof resourcesin Figure 2(b) and weak becauseof this. This seems obvious, but the importantpointis thatthe situationof Figure 2(a) would occur when Position A is located close to the apex of the hierarchy,wherecontactwith the environmentwouldgiveit controloverimportantorganizationalresources.The situationof Figure2(b) would occurwhenPosition A is locatedin the heart of the technicalcore,whereit wouldbe isolatedfrom environmentalcontact and thus bereft of resource control. affects patternsof interdependencein the technical core,andenvironmentaffectspatternsof dependence at the organization'sboundary.Whatis significant for Thompson is that these two sources of dependence are segmented"into self-sufficientclusters" so that "dependencetendsto be confinedto that domain" (1967, p. 129). Moreover, it is clear that Thompsonhereis referringto lowerhierarchicallevels, becauseit is the localizationof dependencein selfsufficient clusters that permits decentralization. "Decentralizationdilutes the power structureby creatingmorepowerpositionsbut limitingthe organization's dependenceon each" (1967, p. 129). This furtherimplies that if functions cannot be segmentedinto self-containedclusters,they will remain centralizedat the top of the hierarchy.Thus, at higher levels of the hierarchyduties are general ratherthanspecific,becauseadministrative workcuts acrossspecializedfunctions.Locatedat the centerof allocativedecisionmaking,administratorsmust acquire and control importantresourcesbut simultaneously be centrallypositionedto achieveeffective coordinationof the allocationprocess.Higherlevels of the hierarchytherefore are characterizedby a positive relationshipbetween resourcecontrol and networkcentrality,ratherthanthe negativerelationship found at lower levels. Finally,considerthe relationshipbetweennetwork centralityand hierarchicallevel. The mediationof this relationshipby resourcecontrol is particularly interestingbecauseit seemsto qualifythe widelyaccepted conclusions of Bavelas (1950) and Leavitt (1951)regardingcentralityin interactionnetworks. These researchersfound that when faced with the need to solve problemsjointly, the structureof interactionamongindividualswithingroupsinevitably led to centrallylocated membersacting as decision makers and peripherallylocated members acting merelyas information-relayers.In other words, the responsibilityfor making decisions, which can be regardedas a progenitorto hierarchicalauthority, was a direct consequenceof networkcentrality. The emergenceof a positiverelationshipbetween hierarchicalauthorityand networkcentralityis conditioned,however,by resourcecontrol.To illustrate why this may be the case, considerFigure2. According to the Bavelasand Leavittexperiments,Position A scores higherin termsof networkcentralitythan do positions B, C, D, and E and thereforeshould have more powerin decisionmaking.However,the changein directionof resourceflows betweenFigure Conclusion The organizationalliteraturedealingwith power quite rightly has differentiatedthe concept into a numberof analyticallydistinctdimensions.Poweris a multifacetedphenomenonand must be analyzed as such.

An examinationof the processesby which certain goalsareset in place,anddefinedas criticaland functional, permitsthe question:Criticaland functional for whom? (Astley & Rosen, 1983). Finally,sucha radicalapproachcan be linkedprofitablyto the extensionof poweranalysisin another direction:to extraorganizational structuresof power. AstleyandVande Ven(1983)havearguedthatpower relationswithin organizationscan be satisfactorily analyzedonly by referenceto the prioritiesand interestsof powerfulstakeholdersoutsidethe organization. Intraorganizational powerrelationscanbe seen, in part,as "epiphenomena"of forcesthat permeate in a broadersocial context. Thus it becomesnecessary, followingHickson,Astley, Butler,and Wilson (1981),to linkstructuresof intraorganizational power to the power structureof the wider environment itself. does not focus on the dynamicprocessesthat produceand, overtime, changetheseconfigurations.In this respectmuch can be gained by integratingthe presentstructuralapproachwith the organizational behaviorliteraturedealingwithindividualand group processes,becausethese are relevantto poweranalysis. Second, researchon the individualand groupdynamicsunderlyingthe productionof powerstructures also can shed light on the dialectical processes throughwhichparticularpowerregimesareinstituted (Benson, 1977a, 1977b).
