The course objectives and subsequently the module objectives in this course are built around the DASA Competence Framework. So, before you learn about the objectives of the course, it is important to understand the DASA Competence Framework.

Knowledge Areas and Skill AreasThe DASA Competence Framework identifies (8) Knowledge Areas and (4) Skill Areas that are relevant in DevOps.

Knowledge Areas Skills Areas

The following points suggest what is meant by each skill area: � Courage covers more than just having the confidence to act.

It is also about trusting team members, being open, and being prepared to speak out.

� Teambuilding focuses on ensuring the team bonds to a set of people that interact effectively in a common cause. In the course of doing so, they hold each other accountable and support each other.

� Devops Leadership is not reserved for management or other formal leadership positions. It is fundamentally about facilitating teams to reach at high performance through formal and informal leaders.

� Continuous Improvement is a built-in desire to do better today than the team did yesterday. At the same time, it includes recognizing successes and failures, celebrating both for what they are/or opportunities to learn. This skill is also the basis for creating an autonomous team with all the knowledge necessary to serve the customer.

The following points suggest what is meant by each knowledge area: � Business value optimization is to look at the use of the IT

service in real life. The DevOps team should know about the usage of their IT service in practice and its impact on the further development of the service. It is vital to understand the business process the IT service supports to be able to build a business case for improvements.

� Business Analysis is to analyze data and processes to determine what improvements have the maximum effect on the business. It is about detailing the requirements but also doing Value Stream Mapping. It also includes the ability to refine the backlog of desired improvements.

� Architecture and Design encompasses, principally, the overall design of the IT service including creating a view of the direction in which the service is developing. In other words, it involves defining architectural scenarios.

� programming is the core knowledge area for all DevOps team members. Programming is essential to develop applications. However, with the creation of infrastructure as code, programming has found its way into the infrastructure domain. In both the cases, application and infrastructure, it is crucial for people managing the Production environment to have strong programming knowledge.

� Continuous Delivery covers the central DevOps process of getting the newly developed code from the development environment into production using a solid set of tests with reliable version control.

� Test Specification is closely related to Business Value Optimization and Business Analysis. Developing a set of tests is a good way to specify the functionality to be developed. Test Driven Development (TDD) is an example of a method that

promotes this way of developing applications, i.e. describe the required business value in terms of the tests that need to be passed and then develop the code.

� Infrastructure engineering includes knowledge of load balancing and other such performance management aspects. It also means building effective monitoring solutions that work as predictors for incidents or problems. Capacity and availability management are part of this knowledge area.

� Security, risk, and Compliance is vital for all IT products and services. It is essential to integrate this knowledge into the DevOps team rather than relying on outside knowledge. This knowledge area plays a vital role in building Quality at the Source.

Competence Framework in PracticeDASA’s Competence Framework guides organizations to develop high performing teams.

Every individual operating in a DevOps team should be at: � Level 2 - Competent in the (8) Knowledge Areas;

� Level 3 - Proficient in the (4) Skill Areas.

DevOps teams should strive for � Level 4 - expert level in all 12 Areas.

As you will learn later in the course, DevOps strives for autonomous teams that need to have complete set of competencies and skills to build and maintain software quickly and successfully. So, it is important to assess what competencies and skills are required and what are the areas in which the team need to improve. The team’s capabilities can be assessed by performing the assessment of each team member.

An example of the assessment for each member of a team is depicted in the preceding figure. When you roll up each individual’s assessment, you will get a team chart. This chart shows an example of the capabilities on the skills and knowledge areas for a specific DevOps team.

Course Objectives � At the end of this course, you will be able to:

� Discuss the drivers responsible for the emergence of DevOps.

� Define and discuss the key concepts and principles of DevOps.

� List and explain the business benefits of DevOps and continuous delivery.

� Describe the Service Delivery process.

� Explain the automation concepts for the software delivery process.

� Describe how DevOps relates to Lean and Agile methodologies.

DASA: Mastering DevOps in Practice (Knowledge and Skills)DASA Competence Framework recognizes five maturity levels, as shown in the following figure.

DASA recognizes five maturity levels ranging from Novice to Master. The intent of DASA certifications is to bring IT professionals from level 1, that is, Novice to level 4, that is Expert.

� The DevOps Fundamentals certification leads to level 2 maturity that is “Competent” on all skill and knowledge areas.

� The DevOps Practitioner training adds level 3 maturity that is “Proficient” on all the skill areas.

� The three specialization modules lead to level 4 maturity, that is, “Expert” on various parts of the competence framework.

� Level 5 is out of scope for DASA and requires much more than just DevOps specific trainings.

In many organizations, IT continues to be a road blocker than a business enabler. The key challenges faced by organizations are manual releases, low quality of software, sporadic releases, and product backlog resulting in cost escalation. It becomes imperative for the organization to find a solution to these challenges to survive in an extremely competitive and dynamic environment.

The two key teams involved in software development and delivery, Development and Operations, work with contradicting objectives which results in the creation of wall of confusion.

need for Change and stability Causes tension

The typical challenge that traditional IT organizations face is to deal with the wall of confusion between Development and Operations.

Need for Change and Stability Causes Tension

What is the key goal of the Development team?

Wall of confusion

Change Stability

Development Operations

What is the function of Operations team?

Is the Development and the Operations teams connected to each other?

Development is more focussed toward creating new functionalities (Realizing functional requirements / Utility aspects of a service), while Operations is more focussed toward creating a stable environment with a high level of Availability, Security, Capacity, and Continuity (Nonfuntional requirements / Warranty aspects of a service).

The wall of confusion is a combination of conflicting motivations, processes, and tooling. It can result in the following problems in production:

� In the absence of a procedural transition from Development to Operations, the Operations team faces challenges in the production. It gets back to the Development team for solutions resulting in delay.

� The Operations team is involved in managing the Production environment and can share relevant information which can help the Development team. However, lack of communication results in loss of sharing.

� The knowledge articles play an important role in building the cohesiveness between Development and Operations teams.

Wall of ConfusionThink of the wall of confusion as a solid brick wall where no communication is possible between the people standing on either side. They cooperate by sharing something physical, such as a note written on a piece of paper. The traditional way of developing software works the same way. If the Development team is working on an application, they hand it over to the Operations team only when it is complete. This approach has many loopholes and ultimately results in severe problems in production that causes blast like situation.
