The papers in this two-part special issue examine from a range of perspectives the challenges and opportunities in tracking and demonstrating the impact of managing knowledge both inside the walls (in organizations) and outside the walls (in the broader development context). Due to the high number of papers selected, they were divided into two issues, based on their completion dates. We would like to thank all Guest Editors who reviewed and provided feedback on the abstracts and papers, as well as other colleagues who kindly agreed to peer review papers and provide feedback to the authors. We would also like to thank the contributing authors for their papers and for their patience –it has taken considerably longer than we had anticipated to finalize this issue. Finally, we would like to recognize the dedication and hard work of the Editor-in-Chief, Sarah Cummings. It has been a pleasure to work with her on this issue and we look forward to contributing to and supporting the Journal well into the future as members of the team of Senior Editors.
