IV@2015ProjectManagementInstituteBusinessAnalysisforPractitioners:APracticeGuide前言■前言《商业分析实践指南》是PMI基本标准的一个补充。
本指南提供有关如何将有效的商业分析实践应用于项目集和项目的指导,以实现成功的商业成果。
本指南为那些对商业分析学科感兴趣并致力于实践的组织和从业者提供了以下指导广泛收集了历史悠久和最新的商业分析技术和实践,并由经验丰富的商业分析专家和从业人员定义和解释。
描述了这些技术和实践如何使用,并包括许多具体的实例。
本指南将帮助读者获取以下信息:思考哪些实践和技术适用于自己的组织。
思考在不影响他们所支持的商业分析的质量前提下,如何适应和调整技术和实践来满足组织和文化需求。
o2015ProjectManagementInstituteBusinessAnalysisforPractitioners:APracticeGuide■商业分析实践指南本指南旨在鼓励探讨相关领域的实践,这些领域或许尚未达成共识。
商业分析学科及其关联角色不断演进。
该演进最显著的一些驱动因素有:提升对于适应快速变化能力的业务聚焦。
●尽可能有效地提升对于项目交付价值的关注。
●新的和持续发展的方法使干系人和项目团队成员相互协作,以达成实现商业价值的项目成功。
此外,商业分析实践的方法组织如何定制化所选择的实施方法高度依赖于组织、文化和方法论准则。
这些选择也受到组织愿意和能接受变化的程度影响。
并不期望每一位商业分析的实践者使用本指南中提到的所有技术,例如:有些实践者可能认为一些技术是传统的,因此过于受限。
PM认识到敏捷实践者可能期望更多的自适应技术。
●其他实践者可能发现一些技术太新,会有潜在的风险或复杂性。
考虑到所有这些因素,《商业分析实践指南》提供了这些实践作为起点,来确定思维过程和方法,从而改善组织和从业者的方法,并实现有效的商业分析。
PMI引入本指南的目的是确定与PMI基本标准相集成的有效方法。
实践指南是由业界领先的专家编写,本指南也不例外。
实践指南使用相对较新的过程,提供可靠的信息,同时减少编写和分发所需的时间。
PM定义实践指南为标准产品,为PM标准的应用提供支持性的补充信息和指导。
V@2015ProjectManagementInstitute.BusinessAnalysisforPractitioners:APracticeGuide前言■指南并不是完全达成共识的标准,不通过征求意见稿过程。
然而,由此产生的工作可能在后续形成一个完整的共识标准,如果这样,就要遵循PMI标准的记录编写过程。

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。
