Empirical Process Control In Scrum

Empirical Process Control

Empirical Process Control

It is often said that Scram is an Empirical Process, so the question is whether it is true and if so, what does it really mean?


This means that information is collected by viewing, experiencing or using the experiment.

Empirical Process

Is used to handle processes that are complex and are not very well understood.

So let’s see how it is defined.

An Empirical Process Control is seen as a black box and you have evaluated it and done it in output. This is done to define the checkpoints which should be on the predefined points.

So what do we have in the scrum?

We have sprints in the form of a black box, in the sense that the work that is done in Sprint should not be interrupted. We have backlog items which have not been initialized as input and have lost the backlog items in the form of output.

In the form of checkpoints in Scrum we have daily scripts, sprint planning meetings, sprint review meetings and sprint retrospective. Since each sprinting is boxed on time, the checkpoints are always at a predetermined time. Inspection is done at each checkpoint so that you can optimize the Empirical Process with information collected through observation, experience and experimentation.

Another important aspect of an Empirical Process is that the process model (which we work) comes directly from input and output data. So how to work out from the outside process, there should be no possibility of changing it. This is the reason that we do not add more backlog items in Sprint compared to the previous sprint, which proves that we can do this even though it is coming from high management. We need to be truthful and protect the scrum Empirical Process Control.

So now we know that the Scrum is an Empirical Process, but why is it so good? Why not use the defined process? It is very much estimated.

In order to answer this question, we need to look a bit deeper about what is facing the system while developing the system and what is the defined process.

Empirical Defined Process

A defined process has been taken from the first principles, which means science has to follow the rules of nature and other fundamental and well-defined laws.

A more understandable description was made by Ken Schwaber in Agile Software Development with Scrum.

“The defined Empirical Process Control model requires that every piece of work be fully understood. Given a well-defined set of input, each time the same output is produced. A defined process can be started and can be allowed to run till completion, with the same result every time. ”

This is theoretical truth but there will be a variance in the real world but will be held till a minimum. There is no need for feedback because you will always know what to do next.

So here is the variance of Ken Schwaber definition.

“A defined process is a quantity of tightly coupled steps where the output from one stage is input to the next stage and where no overview or evaluation of the process is done for the reaction. Once started, a defined process will run till the end of the stairs. The output should always be the same from the defined process or there should be a slight variance with the input similar to the process. ”

The Empirical Process can be very complicated but it needs to be well understood before execution.

It is typical for a “waterfall” like the process, where everything needs to be defined in the beginning and then you follow a cookbook such as the recipe and you should get a desired result. Therefore, if system development should fit in this process, then it should be highly anticipated, non-constructive and should not demand any ideas during the execution phase in Empirical Process Control.

It’s not that I or many of my colleagues think about system development. For us it is a highly creative and intellectual process that demands a higher level of thinking. We should expect unexpected and be able to take action on it in a complex environment.

Complexity in system development often happens with 3 key areas, needs, technology and people.

– Requirements are often not understood very well, they are transmitted badly and disappear.

– In a system development project we are working with at least 10 different techniques and it is in a small or medium sized project. For example: A bunch of Java, JavaScript (and other scripting languages), XML, SQL, XSLT, JSP, Spring, Web Services, Schema, Maven and other frameworks that we need to meet our needs.

And the people who can change anything in the other two, it means that we have very unpredictable complexity.

So a waterfall like this process is not good for the development of the system, but what about all the other repetition processes that are out there? Should not they work with scams?

To answer that question, we have to look at each of this Empirical Process and see if this is a Most Agile Processes.

How Empirical Process is controlled in Scrum Project?

Empirical Process Control

Generally, in the Scrum method of project management, decisions are taken based on observation and experimentation. There are three main ideas behind the application of Empirical Process: Transparency, inspection and adaptation.

  1. Transparency: It includes all the facets of Scrum process to be observed by everyone whosoever is interested to do so. This promotes an easy and transparent flow of information in the entire organization. This leads to open work culture. Transparency is measured through:
  1. Artifacts: Vision statement of the project, prioritized product backlog and planning schedule.
  1. Meetings: Regular standup meetings and Sprint review meetings.
  1. Information Radiators: Burndown charts and scrum boards.

After the transparency is measured, it is then inspected in the Scrum project using:

  1.     B) Inspection: It is revealed in Scrum through:
  • Use of a unique scrum board and other related scrum information radiators.
  • Collection of feedback from the customer and other stakeholders during the develop Epic and carry out release planning processes.
  • Inspection and approval of project deliverables by the Scrum Master and product owners and the customer in demonstrate and validate sprint scrum process.


  1. C) Adaptation: This happens as the Scrum core team and the stakeholders master the art through transparency. Inspect it and then adapt by making any required changes as well as improvements in the work they are doing.

The changes must match the project requirements and once these are done. One can see adaptation changes in the following ways:

  • Stand up meetings
  • Identifying constant risks
  • Changing the requests
  • Scrum Guidance
  • Check the sprint meeting
  • Check the project meeting

In this way, the entire Empirical Process is controlled in the Scrum project. These three factors determine the success of the entire process in the Scrum project. This is the unique feature of Scrum that makes it different from other scrum projects.

It is nothing but a creation of small sample of the product to check the end results. Empirical Process is an important part because in Scrum, product development is significant and with too many variations in the product groups, there’s a set of defined formulas for the entire process.

In order to support the entire process, it emphasizes on principles such as transparency and self managing teams. Appropriate process is required to generate transparency, inspection and adaptation cycle which is at the heart of Empirical Process.

The main aim of Scrum is to maintain transparency and emphasize on inspect adapt cycle so that groups can continuously enhance their own ways of working. These Scrum practices and Project structure make it easy to start. However, for some reasons, these are incomplete so that groups have space for learning for every situation and adaptation required in complex domains such as product development.

In a nutshell:

Do you feel Empirical Process is maintained properly in your organization in Scrum? If yes, it’s great. If no, find out what’s missing among the three factors. Make sure to cross check everything and then fix the issues to let the scrum process run smoothly.

Empirical Process Control and Scrum Overview

Empirical Process Control - Lean Agile Training

In the Scrum Guide of Ken Schwaber and Jeff Sutherland (the original two founders of Scrum), they describe it as “the framework for developing and sustaining complex products” with Empirical Process Control.

The scrip includes a self-organized, cross-functional team. In simple language, this means that teams have a set of people who have different skills in everyone, but they work together for the same result. A project manager does not control them, because their expertise gives them the power to make decisions for Empirical Process Control.

Teams work in reconstruction, allowing the business to change their needs, but it is definitely necessary for the development group to deliver part of the production work. This is a key thing that makes the script powerful.

Scrum takes its name equally to rugby, where one team works together in a chaotic environment to control one ball. To control the project, it can be compared to a team working together in a chaotic environment.

Empirical Process Control and Scrum Theory

History repeat it-self and unless you do something about Empirical Process Control

The structure is based on the Empirical Process Control principle. The idea is very simple so do not worry about the name. It has three principles: transparency, inspection and adaptation. The idea is that the Scrum team agreed to be transparent (honest) in all those made on the project.

Being transparent means that until the efficiency is ‘not completed’ it completes the development team’s definition of completion. Transparency builds trust among team members. Once the team agrees on transparency, then they constantly check on the progress (inspection) and they are upgraded (adapted) based on what they have seen. There may be improvements in these stereo, values, communication or otherwise sticky. This industry has powerful content, continuous observation and ability to adapt. This way they are improving time and time before, during and after production. This is something that is not possible with the Scrum Developmental Model.

Scam Skeleton

Scroll skeleton is a quick and easy way to explain someone’s process, so I’ll use it to explain the Empirical Process Control.

We start with Product Backlogs, which are nothing more than the list of all products (and their acceptance criteria) that the business wishes to produce. It’s a backlog subset, called Sprint Backlog, breaks into functions and works in a repeat called Sprint. Sprint is a period of less than 30 days and at that time, the team works on their works until it increases the performance of the product and Empirical Process.

Do I remember the small phase of the falls described earlier? Okay, all this happens in Empirical Process Control. There is a gathering and specification update for Sprint before, after the design, implementation and testing needs of some. Above the big Sprint Circle, you will see a small circle. It represents the fact that every day the team inspects the progress and accepts their plans for the day in the daily Scrum Meeting. At the end of Sprint, the potentially shipped increase of the product is delivered. Businesses can review the growth in Sprint’s review and then if they want they can release the new facility (s).

The team then discusses their progress (transparently) during Sprint’s observation, so that they can modify (adapt) things that require improvements or need to maintain good running things. Then the wheel starts again and repeats until the product owner has more to add to the product backlog in Empirical Process Control.
