1.精益模型：
精益是一种有效的方法论，它通过不断改进和为客户创造价值来相信价值流向客户。它优化了可用资源，以创建稳定的工作流程，将客户的需求放在中心。亨利·福特(Henry Ford)在1450年代的威尼斯发现了精益技术。它通常是指专门称为精益制造的一组知识。这侧重于基于需求而非供应的生产。它包含5条原则。
精益模型的好处：
- 提高产品质量
- 提供更高的员工满意度
- 增强利益相关者的可见性
- 可预测地交付客户价值
- 更有效的业务流程
2.敏捷模型：
敏捷是一种众所周知的开发方法，也是许多开发团队(尤其是那些希望创建连续交付环境的开发团队)的最佳方法。它着重于迭代开发，周期短，获得反馈并适应新要求。通过自组织跨职能团队之间的互动来开发解决方案。敏捷是2001年发布的《敏捷宣言》的一种心态，其中包含12条原则和17个软件开发人员编写的4个价值观。
敏捷模型的好处：
- 更好的客户满意度
- 快速开发和交付
- 更加重视最终用户
- 业务与开发团队之间的紧密合作
- 允许后期和进一步的更改

LEAN MODEL |
| 01. | Agile is more focused on continuous delivery through the self organizing cross-functional teams. | Lean is focused on flow of value to the customer. |
| 02. | Agile is always adaptive to change. | Lean is about stable workflow and meeting the customer’s demands. |
| 03. | Agile is designed using different frameworks like scrum, Kanban etc. | Lean is designed using transitions from manufacturing processes. |
| 04. | Agile came out in 2001 and was designed by 17 software developers. | Lean was found in 1450s Venice by Henry Ford. |
| 05. | Agile consists of 12 principles and 4 values. | Lean consists of 7 principles. |
| 06. | Agile delivers products in a dynamic manner in small parts rather than whole products at once. | Lean is used to develop both the quality of the product and the delivery speed as well. |
| 07. | Agile can not be used to cut costs. | Lean can be used to cut costs. |
| 08. | Agile is easier to use for dynamic requirement changes. | Lean is not flexible when the requirements are changed. |
| 09. | Agile believes in end results through responses and feedbacks. | Lean follows a systematic plan for development by eliminating unnecessary things like meetings, documentation etc. |
