Achieving transparency is at the core of a lot of what I do in the fields of demand chain development, strategic alignment, and mentoring leaders. Transparency enables emerging problems and issues to be identified, and addressed quickly, efficiently, and with a minimum of waste in the process, and for opportunities to be grabbed.
However, the downside that sometimes evolves, particularly in closely defined cultures, is that it also enables blame to be pinned on an individual or team, and this is hugely counter productive.
Once transparency is used as a finger pointing exercise, it will not get a second chance, as people learn quickly that it will be counter productive to bring problems to the notice of others, when they run a risk of being the messenger that gets shot.
