Steve McConnell completes the series in which he describes the 28 key principles in his new book, More Effective Agile (Construx Press, 2019). The final principles described are: "Focus on Throughput, Not Activity." Similar to managing to outcomes, adding the nuance that busyness is not the objective—getting valuable work done is the objective. (See page 223 in the book.) "Plan Based on Measured Team Capacity." Agile is an empirical approach; teams and organizations should plan their work based on their measured performance. (See page 232.)"Decriminalize Mistakes." Decriminalize mistakes so that teams surface them without hesitation and you can learn from them. A mistake you don’t learn from penalizes your organization twice. (See page 227.)Make sure to check out the first 8 parts in this series to learn all the principles.
