精益敏捷转型听起来很容易,但做起来很难,很多组织在数字化转型的过程的早期,一到两个团队作为试点团队进行敏捷转型,都能获得不错的转型效果。
随着转型的持续推进,涉及到越来越多的团队转型,这时就会暴露出早期没有发现的一些问题。
我们经常说量变引起质变,如何保证组织转型过程中,大团队从传统的瀑布式开发转变到精益敏捷模式的开发呢?今天我们不谈理论,不谈框架(SAFe,LeSS),我想从一个实操的方面来剖析一些我们实际遇到的困难和一些应对策略。
我们从以下4个方面来分析:产品规划多开发团队的协同集成与测试上线交付我们知道在传统瀑布模式下会产生如下的一些问题产品规划:规划流程长耗时,反馈慢,交接成本高,用户价值

在日常工作中,钉钉打卡成了我生活中不可或缺的一部分。然而,有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚,我总是得牢记打开钉钉应用,点击"工作台",再找到"考勤打卡"进行签到。有时候因为工作忙碌,会忘记打卡,导致考勤异常,影响当月的工作评价。而且,由于我使用的是苹果手机,有时候系统更新后,钉钉的某些功能会出现异常,使得打卡变得更加麻烦。 另外,我的家人使用的是安卓手机,他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说,每次打卡都是一次挑战。他们总是担心自己会操作失误,导致打卡失败。 为了解决这些烦恼,我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习,我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
