| Release — Coordinate releases, schedule release approvals, release automation. | =====Monitoring ====== |
| |
| Configure — Infrastructure configuration, management, and provisioning databases and networks. | Project managers monitor the progress of a project. Three levels of monitoring include: activity levels (daily progress), status reports (weekly progress) , and milestone analysis (monthly progress). Each of these levels helps keep each member of the team and its leaders aware of the project's progress and current status. If one of the levels reveals an inconsistency or a deviation from the project's end goal, the team leader can use that information to steer their team back in the right direction. |

| •A/B Testing ("Split testing")- Used in applied marketing and business intelligence for assessing conversion rate optimization strategies. Executed by delivering unique content to similar user groups to determine the most appropriate conveyance of information. EXP: User group G a is split into pools X and Y. Group X is delivered landing page J, while group Y is delivered landing page K. Exit rates for landing pages J and K are 20% and 50% respectively. The A/B test has shown that landing page J is more effective at retaining users, and therefore should be delivered to users in group G. | |

| •Canaries - A canary test is a push of programming code changes to a small group of end users who are unaware that they are receiving new code. Since the new code is only sent to a small subset of users, a problem in the code will not have a huge impact. Chrome Canary is an example, new code is pushed constantly. | ===== Canaries ===== |

| Triage - Triage is the act of analyzing, understanding, and categorizing a specific set of defects, in preparation for making a repair scheduling decision. For a given set of defects, you need to determine how to act on them and proceed with repairs. The more serious defects, those with the highest priorities, receive action first, usually because of their import or because they are blocking further project activity.
