Responsive strategy, being and doing Agile are keys to effective adaptive leadership within an Agile organization. Jim Highsmith spoke recently at the AgileAustin hosted event about adaptive leadership and how it can accelerate and sustain the organizational agility. He said that agile leaders should focus on aspects like quality and speed to value as executive levers to achieve business goals.
The leaders should create an Agile business strategy with focus on responsiveness over efficiency and develop an IT Agility roadmap. The strategy should also include a continuous delivery of the software products. IT teams shouldn't just limit their process to Continuous Development or Continuous Integration but enhance it to include the Continuous Delivery (which includes all three phases, Continuous Development, Integration and Deployment). Jim talked about different levels of agility in organizations like operational, portfolio, and strategic level agility. Everyone should start looking at the areas within their companies where responsiveness and agility could be strategic as well as tactical/operational to the business.
The adaptive leadership is two dimensional which includes doing Agile and being Agile. Doing Agile requires leaders to understand strategic agility from a business perspective as well as specific principles and practices to help build Agile organizations that can weather business turbulence. Agile leaders should use the following execution levers to achieve business goals of responsiveness (agility), profitability, market share and customer satisfaction.
The second dimension of adaptive leadership is “Being Agile”, which is based on values and principles, requires leaders to realize how practices like continuous delivery and a mind set of sustainable agility combine to create highly responsive IT organizations.
Adaptive leadership behaviors are different from the traditional leadership ones. A traditional manager focuses on following the plan with minimal changes, whereas an agile leader focuses on adapting successfully to inevitable changes. Jim also mentioned other agile leadership characteristics like being adaptable versus predictable. Agile leaders also follow an Envision-Explore approach rather than a Plan-Do approach. They are facilitative in nature and encourage a collaborative engagement among the agile team members. He said that self-organizing doesn't mean anarchy and adaptive leadership doesn't mean no leadership. As a leader, it's ok to be wrong but it's not ok to be uncertain.
Jim concluded the discussion by saying that all models (Waterfall, PMI, CMMI, Deming, Scrum, XP, Kanban, and Lean) have some limitations but all of them are potentially useful and the best agile implementations are usually "hybrid" implementations. We should improve the effectiveness of each model based on the situation.
