On somewhat aside, While it&#x27;s true that most &quot;Traditional Project Management&quot; implies waterfall, it&#x27;s not quite true that &quot;Water can&#x27;t flow up the waterwall&quot;. At least for the last few editions, PMBOOK explicitly indicated that planning, execution, and monitoring are iterative and feed into each other.<p>There needs to be, and is, more to Agile than just the idea that you can (re-)plan during execution - no sane traditional&#x2F;waterfall framework would insist on an unalterable &quot;steady as she goes&quot;. There&#x27;s always the urge to learn and improve from execution experience as early as possible.<p>To Article&#x27;s point then, if your organization&#x27;s issue is that you&#x27;re not learning or implementing lessons, TPM is not the only problem. There&#x27;s something in your company&#x27;s organization or culture that prohibits it - and will continue to do so.
