There is a growing recognition of the increasing importance of 'local leadership' practice within multi-unit service contexts, given the threat to costly land-based retail infrastructures from smart technologies. Multi-site organizations are economically significant, but currently under-researched and poorly understood. In Effective Multi-Unit Leadership, Chris Edger looks at that key managerial cohort in the retail, hospitality and service sectors operating between the centre and unit - the Multi-Unit Leader (MUL). This district, area or regional manager, is tasked with maximising revenue and profit from a complex and ambiguous positional space, being sandwiched between the centre and unit, facing the MUL how do they motivate unit managers and team members to provide great service whilst simultaneously fulfilling the Centre's compliance agenda? Based on extensive case study research across a range of multi-unit service organisations, Edger advances an Integrated Model of MUL that elucidates how key activities (sales-led service, systems and standards - 3Ss) are driven through behavioural practices (commitment, control and change - 3Cs) underpinned by MUL personal characteristics (expertise, emotional intelligence and energy - 3Es). Central to this model is the notion of 'portfolio optimisation through social exchange' (POSE) where MULs apply 'local leadership', leveraging their portfolios through the deft application of exchange-based currencies. Replete with case studies, Effective Multi-Unit Leadership will appeal to high potential unit managers; existing multi-unit leaders who want to improve their performance levels; and retail service directors wishing to train and coach their direct reports; as well as business educators and those with an academic interest in organisational studies.
