forward, but changes not put back into version control. Focused on version control and automated environment creation – time reduced from 8 weeks to 1 day b. ENABLE ON-DEMAND CREATION OF DEV, TEST, AND PRODUCTION a production-like environment ii. Don’t just document the environment specifications 1. Create a common build mechanism to create it on demand 2. Codified in automated environment build process iii everything, everything is checked into version control 1. Application code & dependencies 2. Environment scripts & creation tools 3. DB scripts and reference data 4. Containers 5. Automated tests

m/postgresql-13.service #pg-13版本，修改systemd服 务文件，指定数据目录 #修改这行：Environment=PGDATA=/var/lib/pgsql/13/data/ 改为新的路径，如 下： Environment=PGDATA=/data_pg/data/ # systemctl daemon-reload # systemctl restart /usr/lib/systemd/system/postgresql.service #pg-10版本，修改systemd服务 文件，指定数据目录 #修改这行：Environment=PGDATA=/var/lib/pgsql/data/ 改为新的路径，如下： Environment=PGDATA=/data_pg/data/ # systemctl daemon-reload # systemctl restart

8 of the 10 exploits were over 10 years old. i. ENSURE SECURITY OF THE ENVIRONMENT i. Once a hardened, risk-reduced environment is put in place, it must be monitored to ensure it stays in known good resets 3. Email resets 4. PII or private changes l. CREATE SECURITY TELEMETRY IN OUR ENVIRONMENT i. Create environment telemetry 1. OS changes in production, build infrastructure, etc. 2. Security group

Open Discussion on Project Planning Planning in an Agile Environment Key Tenets  Planning should focus strongly on the near term  Eliminate waste caused by planning for eventualities that never come makers and other stakeholders to become more familiar and comfortable with processes in the Agile environment, which enables a more collaborative and productive review process.  Provide information to all more from the development sprints and releases. Cost Estimation  Cost estimation in an Agile environment is challenging  The challenge within DoD is often a resistance to allocate budget for a program

Planning: The idea that we should make a plan and then stick to it is a terrible idea in an environment of uncertainty and change. It has dominated the IT world because it appears to offer predictability quickly from requirements to deployment.  The developer uses a powerful integrated development environment (IDE) that centralizes the tools that help him or her do the job.  The code is built automatically viewed as a filter; a way of allocating scarce IT resources among many competing projects. In an environment where IT has a limited capacity and the company’s needs for IT are insatiable, governance provides

would get over there fix “their” problems.  Discovered, multiple teams involved in snowflake environment support.  The practice team wasn’t the same as the game time team.  Segregated technical and More opportunities to fail, iterate, and improve.  Incented innovation and optimization.  Environment homogenization and assimilation – no snowflakes  Deployment methodologies, automation, monitoring

application can be deployed into the production environment. Deployment frequency: how often a new release can be deployed into the production environment. Production failure rate: how often software fails

quarters to lead times measured in minutes, the constraint usually follows this progression: a. Environment creation: b. Code deployment: c. Test setup and run: d. Overly tight architecture: iv. ELIMINATE ensure functions as desired iv. Operations – the team responsible for maintaing the production environment and ensuring service levels are met v. Infosec – team responsible for securing systems and data

this approach can focus IT planning, reduce risk, eliminate waste, and provide a supportive environment for teams engaged in creating value. If you missed last month, you can find the handout for Part Chaos: I began this book posing the question of how senior IT leadership can play a role in an environment of autonomous teams working directly with product owners from the business. The answer, I think

“prosperous economy”; 3. Making Washington a national leader in sustainable energy and a clean environment; 4. Healthy and safe communities; 5. Efficient, effective, and accountable government. These
