First, give conclusions that can be used for decision-making
The failure may result from delivery defects, misperceptions of demand, client environment, data, third-party interfaces or inadequate online preparation. The technology should be either to resume operations or to return to the original version before locating the underlying cause; business should be based on needs, testing and responsibility records to make adjustments, changes or losses.
What conditions need to be identified before judgement is made?
The same question may have different answers under different business, data and project phases. It is suggested that the following conditions be checked and that the common findings on the web be incorporated into their own projects.
Suggested order of advance
First, we'll be clear about the target and the border.
Immediate preservation logs, data, versions and evidence on site.
Validation Key Dependence
Recovery of critical operations and completion of independent cause analysis.
Development of assessable outcomes
(b) The formation of a fine-tuning list, priority, duration and test sample.
Make sure you decide the next step with the real results.
After the review, the batch is set up and the final liability and legacy issues are recorded.
How do you understand it in the actual business?
The system is re-created after the order is created and the team cannot remove it manually and then claim resolution. The re-entry, backup data, analysis of the re-referral, etc., and re-test should be stopped before using real abnormal sample re-checking.
The easiest pit to step on.
Multiple unknown versions continued to be released during production failures
The parties discussed only responsibility, without first protecting data and operations
Renovation only for current cases, without additional return and monitoring
How should we end up receiving and confirming?
The review and acceptance should include the cause, scope of impact, data processing, code version, test and return, and release of the return and monitoring results.
When preparing to communicate with suppliers or internal teams, it is recommended that current processes, representative samples, existing systems, planning time and budget levels be brought. First, the unknown items are clearly marked, and then the decision is made to use diagnostics, PoC, fixed-range projects or ongoing research and development, which is usually more reliable than a direct demand for a price and duration without borders.
