code named Phoenix Project, is critical to the future of Parts Unlimited, but the project is massively over budget and very late. The CEO wants Bill to report directly to him and fix the mess in ninety

Pyramids h. ENSURE TESTS RUN QUICKLY (IN PARALLEL, IF NECESSARY) i. Design tests to run in parallel ii. Enable different test categories to run in parallel iii. Generally, limit manual testing if automated Enable and Practice Continuous Integration a. Branching – Pros & Cons i. Pro – Allows work in parallel while minimizing potential breaking impacts to trunk ii. Con – Branch work, in isolation, becomes environment, test, c. Swing traffic to new environment, Rollback by swinging traffic back 2. Database changes a. Create two DB – put one in read only mode, backup & restore to new environment, swing

and Operations throughout the software lifecycle, embracing a continuous monitoring approach in parallel instead of waiting to apply each skill set sequentially.  Security risks of the underlying infrastructure
