Intuit Confidential and Proprietary ‹#› We are on the Journey to Doing RESTful APIs Well (1) Opportunistic: We do things well locally a portion of the time but successes are not necessarily reproducible within teams nor across our organization. (2) Systematic: There are methods for the things we do well that enables repeatable success but methods are not available for all that we do and teams are still mastering what methods exist. (3) Enterprise: We have a comprehensive set of methods for the things we do that are well-understood and used across our entire organization, product quality is improved. (4) Measured: We measure outcomes effectively to drive execution improvements and we are successful at tuning whatever needs adjustment to be a better service delivery organization. Product quality continues to improve and execution becomes more efficient. (5) Industrialized: We regularly offer Intuit-leading methods to the enterprise and there are only small needs for organizational tuning. Products are consistently produced quickly and with high quality.
