Gordon Skinner at techPortal – Agile Smells:

“There are a number of problems, or 'smells', we have identified in the Agile process that could be having a negative impact on all your good intentions.”

These are the ones I recognize from our Scrum practice: “Hit By A Bus”, “Fuzzy Definition Of Done”, “Anonymous Author’s Task”, “Premature Architecture”, “Ramble On”, “Turn Up, Tune In, Drop Out”, “Hidden Impediment”, “Off Topic”, “Memory Problems”, “Problem Solving”, “Pulling the thread”, “Scope Creep”, “Practising Insanity”…
