Vacanti. For me a must read to get a deep insight in metrics for agile environments.  \nWith this blog post I summarize my highlights and key learnings. It’s just a fast overview and maybe provides already some ideas for you too, what to read next 􀁾 Predictability is of high importance! As an important question from our customers, we need to answer: When will it be done?  \n“The only metrics that entrepreneurs should invest in are those that help them make decisions”( Eric Ries – e.g. on Vanity Metrics vs. Actionable Metrics )  \n“If a metric does not offer predictive power, capturing that metric is waste”(Troy Magennis)  \n1 – Definitions  \nFor me after a longer journey on the web a simple, speaking and coherent definition for cycle time, WIP, throughput and flow efficiency.  \nFLOW: Flow is the movement and delivery of customer value through a process –(as we build for the customer) therefore our whole process should be oriented around optimizing flow.  \nACTIONABLE METRICS: The set of metrics that will suggest specific interventions that will result in the outcomes you are expecting  \nARRIVAL POINT: A specific point where a unit of work transforms from being just some arbitrary idea into being a legitimate work item that is to immediately be acted on and  \ncompleted.  \nDEPARTURE POINT: Defined as delivery to an actual end user or delivery to some other downstream team or process  \nWORK: Any direct or indirect discrete unit of work of customer value is a candidate of work – named as work item (story, epic, feature, requirement, use case, enhancement,…) WORK IN PROGRESS – WIP: The total count of items currently being worked on; the number of items that we are working on at any given time; all discrete units of customer value that have entered a given process but have not exited.  \n predictor of over overall system performance  \n all work items between arrival point and departure point  \n can be segmented across different types  \nCYCLE TIME: The amount of elapsed time that a work item spends as Work in Progress.  \n How long it takes each of those items to get through our process?  \n How long to complete?  \n When will it be done?  \n Can also be used as a predictor of cost  \n The amount of time it takes to get customer feedback  \nUnpredictability lies it the time an items spends waiting to be worked on – that’s why it’sthe elapsed time that is important.  \nTHROUGHPUT: The amount of WIP completed per unit of time.  \n How many of those items complete per unit of time?  \n How many features am I going to get in the next release  \nUnderstanding throughput at each step will help to identify the constraints in the workflow – find spots for process improvements  \nFLOW EFFICIENCY: Ratio of total elapsed time that an item was actively worked on to the total elapsed time that it took for an item to complete.  \n not actively worked = waiting to be pulled, waiting for feedback  \n often a starting point of 15% flow efficiency  \nLITTLE’S LAW:  \nAverage cycle time (CT) = Average WIP (WIP)/Average Throughput (TH) TH = WIP/CT  \nWIP = CT*TH  \nimplies that increasing WIP leads to a higher CT and vice versa – check to reduce WIP to increase CT … in order to get stuff done faster, you need to work on less (on average)  \nAverage items in queue = Average Arrival Rate * Average Wait Time L = lambda * W  \n L = average number of items in the queuing system  \n l","cbCaiggJvJJ7Pd3B","https://ap.wps.com/l/cbCaiggJvJJ7Pd3B","pdf",2067023,"English","# Definitions\n## Cycle time, WIP, throughput, and flow efficiency\n## Little’s Law\n# Cumulative Flow Diagrams (CFD)\n## What CFDs show\n## Important properties and assumptions","[{\"question\":\"What is predictability in agile, and what question should teams answer?\",\"answer\":\"Predictability is about understanding when work will be done.
