Integration of the practice of mindfulness within action learning as an added component within a post graduate leadership programme: an account of practice

This account of practice provides a practical example of the use of mindfulness practice within action learning which was a component of a bespoke UK Business School post-graduate leadership development programme commissioned by an English NHS Mental Health Trust aimed at improving the leadership capacity of mid-level managers through work-based learning. The article discusses background and context of the programme followed by how application of mindfulness exercises was integrated within the action learning process to encourage participants to be ‘in the moment’ as an added component of their leadership development. The aim of the paper is to share examples of practice applied within action learning. Finally, the paper asserts that the application of mindfulness exercises helped to enhance the action learning process by creating a calm, focused space for individual and collective reflections, enhancing the quality of engagement and enabling action learning members to take a more pragmatic approach to addressing the work issues raised within the action learning sets.     

A Multipart Project Planning and Tracking Exercise

Project Management is an important skill for business students to develop. Although project‐oriented activity is very common, the success rate for projects is poor. Many projects fail due to poor planning. This article describes a multipart class exercise used to teach elements of a project management methodology to undergraduate and graduate business students. Over the course of the eight‐part exercise, student teams iteratively develop a project plan and Gantt chart, an initial and detailed project charter, a variance analysis model, and a status report. Students are taught an iterative top‐down planning process using a technique we term the ODW (Objectives–Deliverables–Workplan) model. Students are introduced to Microsoft Project and use the tool to develop a project plan that becomes part of a more detailed Project Charter. In the final stages of the exercise, students collect results, update their plan, and produce a project status report.
