Activiti

是一个工作流引擎，activiti 可以将业务系统中复杂的业务流程抽取出来，使用专门的建模语言(BPMN20)进行定义，业务系统按照预先定义的流程进行执行，实现了业务系统的业务流程由activiti进行管理，减少业务系统由于流程变更进行系统升级改造的工作量，从而提高系统的健壮性，同时也减少了系统开发维护成本。

BMP

BPM ( Business Process Management)，即业务流程管理，是一种以规范化的构造端到端的卓越业务流程为中心，以持续的提高组织业务绩效为目的系统化方法，常见商业管理教育如EMBA、MBA等均将BPM包含在内。
企业流程管理主要是对企业内部改革，改变企业职能管理机构重叠、中间层次多、流程不闭环等，做到机构不重叠、业务不重复，达到缩短流程周期、节约运作资本、提高企业效益的作用。

BPMN

BPMN ( Business Process Model And Notation) .业务流程模型和符号是由BPMI ( Business Process Management Inigtive )开发的一套标准的业务流程建模符号，使用BPMN提供的符号可以创建业务流程。2004 年5月发布了BPMNI.0规范.BPMI于2005年9月并入OMG (The Object Management Group对象管理组织)组织。OMG于2011年1月发布BPMN2.0的最终版本。
