What is Agile and why knowledge workers use it?

• For any Knowledge workers (software engineers,
  doctors, lawyers, accountants etc..) there are
  two important components they emphasize on
• Process
• Quality
• Since knowledge work is less structured and
  invisible, we as knowledge workers continuously
  learn, innovate and emphasize on changing things.
  This is when we adapt a process called Agile.
• Agile is a process that is iterative and
  incremental where small sections are completed
• for frequent inspections and adaptability.

Twelve Guiding Principles of Agile

• Highest priority is to satisfy the customer
  through early and continuous delivery of valuable
• software.
• Welcome changes, even late in development.
• Deliver working software frequently, from a
  couple of weeks to couple of months .
• Business people and developers must work together
  daily throughout the project.
• Build projects around motivated individual.
• The most efficient and effective method of
  conveying is face-to-face conversation.
• Working software is the primary measure of
  progress.
• Promoters sustainable development. The sponsors,
  developers and users should be able to maintain
  a constant pace indefinitely.
• Continuous attention to technical excellence and
  good design enhances agility.
• Simplicity.
• Self organizing teams.
• At regular intervals, the team reflects on how to
  become more effective, then tunes and adjusts
  its behavior accordingly.

Lean
Lean Product Development The entire reasons why
projects prefer to implement Agile is to reduce
waste. The main idea of Lean is to reduce
waste. 7 Principles of Lean Core Concepts 1.
Eliminate Waste Lean ideology is to eliminate
waste. Any value that does not either add or
benefit customer product is considered as waste.
Lets consider adding extra features to the
product beyond requested by customer is waste of
time, resources that could be useful on some
other projects and budget. There are Seven
wastes of Lean 1.1.Partially done work
2.2.Extra processes 3.3.Extra features 4.4.Task
switching 5.5.Waiting 6.6.Motion
7.7.Defects 2. Amplify Learning For knowledge
workers not just limited to people in the area of
technology, a medical practitioner or a teacher
should continuously upgrade their skills. Keep
themselves abreast with new dimensions in their
required fields. The best way is to communicate
and getting feedback and reflect on what we
learned or what we should learn.

1. Deliver Fast The entire reason for delivering
   the product as early is to get feedback. In Agile
   we go through multiple iterations of the product
   and each iteration as we know is a mini project.
   Feedback enhances us to incorporate any changes
   into next iteration. By doing this we continue
   to build high quality in the product.
2. Empower the team One of the core Agile
   principles says is to motivate people. By doing
   this we can assure the team that "am here to
   support us regardless of the outcome. Because
   removing the fear and giving them chance to
   explore options is very important. This build
   confidence in the team and empowers them.
3. Optimize the whole As the saying what we
   measure is what we get. To get the best out of
   everything not just limited to product quality
   but also team members, individual contractors,
   systems etc. anyone, anything involved needs to
   be measured or optimize as a whole to get
   maximum results.
4. Build quality in Again as per couple of
   principles, Agile enhances good design by
   continuous attention This is one of the reasons
   we go through multiple iterations delivering the
   product frequently for getting the feedback. Lean
   focuses in building high quality by implementing
   various techniques.
5. Defer decisions Lean encourages deferred
   decisions because some decisions that are
   irreversible can be done really late in the
   project. In this way we can eliminate risk in the
   project.

What is DevOps
DevOps is an idea that was sprouted in the
context of, the Agile movement. Its a term for a
group of concepts that had been catalyzed into a
movement and is rapidly spreading throughout the
technical community. It is a set of modern IT
practices that bring software developers and
operations staff to work more collaboratively.
Organizations approach Devops by applying lean
principles to continuously manage changes,
obtain feedback and deliver changes to users by,
Eliminating any activity that is not necessary.
