What is Clean Code and Why it Matters?

What is Clean Code and Why it Matters

Clean code is a reader intensive development style that produces software that is easy to read, write and maintain. Developers are often tempted to consider their work complete when the application operates as expected. But we are not merely writing code for computer consumption.

We all know that programming is the art of telling another human what one wants the computer to do.

Clean code is about knowing that your audience is not just a computer, but real-life humans! With this norm in mind, let’s review some simple reasons to why clean code matters.

1. You’re an author

An author is someone who practices writing as a career. Developers write all day long. However, it is easy to forget that each line of code we write is expected to be recited 10 or more times by humans. These humans are our fellow co-workers, who are busy fixing bugs and adding features.

Great authors are known for writing books that tell clear, compelling stories. They use tools like chapters, headings, and paragraphs to clearly organize their thoughts evidently and guide their reader. Developers work in a very comparable system, by using different jargon of namespaces, methods and classes.

Clean coders use these tools intelligently to manage the complexities and tell a clear story.

2. It is foundational

In the recent years, software practices like professional refactoring and unit testing have received immense attention. These practices hoist code quality and maintainability. Executing clean code principles is an opening skill that pays off, especially well when it is time to refactor a code or bring a code under test. Clean code principles produce highly modular source codes which are easier to read and test. If you entertain these practices as part of a house, clean code is the foundation of it.

3. Justify your technique

Imagine yourself sitting in a technical interview. If you are asked about the quality of your code, can you provide a professional and a rational justification? Or would this be just you?

If that is all you can say about writing clean code, then it’s a bad sign. If you have never systematically considered the quality of your coding style, there is ample amount of opportunity for improvement. The developers who write clean code are able to carry many solid patterns, activities and techniques used to keep a code clean. Nevertheless, clean code doesn’t come about by accident. It requires a thoughtful and steady focus on clearly transmitting intent.

Structuring a vocabulary around clean code is not just useful for interviews and enriching your own code quality. It also nurtures level-headed conversations in code reviews by starting a common terminology and framework for discussing the readability of the code.

4. Reading is hard

Professional software companies often pride themselves for their knack to solve difficult problems. However, writing code is relatively easier than reading. This is why so many developers are attracted to drafting rather than doing the hard work of reading and twigging the existing code. Since reading code is challenging, if you write code that you are barely able to follow as you write it, you will be unable to comprehend it later. Professional developers write so many codes, that after a few weeks of their separation, most of the structure and design choices fall out of remembrance. It is like investigating a project with a fresh viewpoint. Not being able to realize your own code after a few weeks can be a really disheartening situation.

5. Technical debt is depressing

Writing confusing and sloppy codes inject technical debt into projects. And while it can be useful when considered in context, too much of technical debt is discouraging and pushes talent away from the organization. When easy things start becoming hard, developers often start to vote with their feet and go somewhere else. Developers derive more job satisfaction out of the quality of their work than the quantity. Technical debt decreases the chance of reprocessing and sets a low bar for quality all through the rest of the code base.

6. You are Lazy

Professional developers endeavor to be the good kind of lazy. This sluggishness is based on laying extra care onto the code so that it is not so hard to write honestly, and is easier to work with in future. Writing clean code doesn’t take long. And once you comprehend the principles, you can actually code more quickly because brief and expressive codes are easier to manage.

When stressed, it’s tempting to cut the corners and ignore the best practices. However, being sloppy eventually slows us down in the long-term, as a result of the increased rate of bugs and the long-term costs of future maintenance. History is evident; it is unlikely that you will find time to clean it up later, so why doesn’t do it right in the first place itself?

7. Don’t be a verb

While the other reasons are solid, this one is the clincher: Everyone is aware of the former developer whose name became a verb to define the dirty code.

Comments like this are a kiss of death for long-term employment prospects. Being acknowledged in writing clean code is an inordinate way to assure that your co-workers look forward to work with you and your code henceforward.

Summing up:

There are three essential principles to write clean code:

a) Select the right tool for the job

b) Enhance the signal-to-noise ratio

c) Try writing self-documenting code

Why Should You Adopt Agile Software Delivery Approach?

Why Should You Adopt Agile Software Delivery Approach

‘Delivering Quality at Speed’ is the success chant in today’s highly-competitive business world. The customary approaches for software development have divided development and testing into two diverse steps- developers build a feature and the QA team tests it for defects.

With the eventual growth of the product, the testing time and efforts also grow exponentially. This welcomes a cold choice for the project managers- either to delay the release or refuse to test. ‘Agile’ was born in need for a better software development approach that allows developers and testers to decrease the number of bugs in the code and to identify bugs early in the code in that order.

The agile approach helps organizations manage predictability while driving alliance and transparency across teams, and adopt a different outlook to be successful. The development cycles, in agile environment, break tasks into small increments. It supports teams to deliver working software more cooperatively and with improved quality.

The agile software development approach offers momentous benefits to the business- better competitive differentiation, accelerated time to market, high-quality software that enhances customer gratification.

The 10th Annual State Agile Survey makes it clear that agile software development has grown progressively over the last decade. The number of organizations, comprising both the startups and large enterprises, accepting agile continues to increase each year.

We here have a quick snapshot of the top 10 reasons (as stated in the 10th Annual State of Agile Survey) to embrace agile software delivery:

1. Speeding Product Delivery – the agile development approach allows the enterprise to deliver high-quality software within fast release cycles that is more in line with the needs of the user.

Shorter sprints in agile development approach are gaining thrust to keep up the speed of the development process constantly with the business goals.

2. Enhance abilities to manage the varying priorities Agile software development not only requires teams to develop and test rapidly but also to deliver developments to the products and services faster to the customers.

Guaranteeing that enhancements and changes required by customers in a reliable and usable manner required to take an agile approach through every step of the project.

3. Increase efficiency Organizations ought to be on a continuous lookout to achieve better business consequences. They require a better way to improve the methodologies and skills that IT staff practices to deliver  software.

The agile methodology allows increased productivity through more effective communication while being highly reactive to the ever-changing demands of the customers.

4. Improve software quality In an agile environment, the development and QA teams work together aiming to develop software rapidly in close collaboration with the customer.  Agile techniques assess and improve the software quality while offering increased customer value.

The development and Testing teams cooperate quite well in an agile environment, and also aim to develop software rapidly in close collaboration with the customer.

5. Enhance delivery expectedness – Something clients usually care the most about is predictability. They want teams to be good at making and keeping promises, reliably deliver work that is efficiently tested, amended codes at the end of each sprint. Stable predictable programs are not possible without predictable and reliable teams, particularly when there are numerous dependencies among the teams.

Using an agile approach for software delivery teams can plan, coordinate and deliver enough predictability along with a release level commitment.

6. Improve business/IT placement Organizations need to mend the business and IT placements to achieve higher value for their business. An organization needs to be effective and efficient to be competitive. The fast changing business environment calls for invention and agility. Organizations need to focus on IT to implement the right systems in the right way to meet the needs of the business. It should step towards business/ IT alignment by aiming on a process to be improved while considering the technology and infrastructure.

An agile approach empowers the association of all the IT operational processes: Change – Problem – Incidents – IT Operations perfectly. Furthermore, it focuses on reduction in time and effort, cost and investments in designing, recording, dis-positioning and testing.

7. Improve Visibility of the Project Visibility is the key to quickly adapt to the needed change. In the lack of project visibility, it is difficult to track and measure improvements in productivity. As much as the top management of an organization needs to know, the teams associated with the development and delivery of software should also know which direction they are heading towards.

Numerous development, testing and operation teams must be aware of the present-day state, the performance and the objective of the project and the organization. Refining the leadership and team visibility through agile approach provides customer value early and often.

8. Decrease project risk – Agile is considered an effective approach for software development that characteristically reduces the risks in software development. Software development in sprints consists of agile techniques such as sprint retrospective, sprint review etc. All these techniques provide continuous feedback which helps prevent deviations between expectations and the completed software.

Using agile, the scrum teams prioritize the highest value and highest risk requirements first. They use current agile artifacts and meanings to manage risk.

9. Improve team optimism – Agile approach emphasizes on better communication and cooperation among different teams. The nature of the agile approach is to keep the team motivated about the challenges in the future. The scrum meetings, retrospectives, prioritization, feedback mechanisms keep the team environment dynamic and up-to-the-minute. The inherent characteristics of the agile approach include Seamless communication, self-organization, high association, project visibility to all the stakeholders etc. which brings a positive change and keeps the team motivated.

Also, the communication through various forums and discussion boards are the basic fundamentals of the agile approach. The approach demands an organization to listen to its employees, communicate its strategies with employees and identify employees for their determinations and accomplishments.

10. Improve engineering discipline Proper adoption and implementation of the principles and practices of the agile approach empower the team members to achieve and enhance the quality of software rather than just completing the work. An important component of the high-quality product is always a good and accessible design and architecture. When an organization plans to adopt the agile principles with a goal of delivering high-quality product, they should also embrace sound engineering discipline.

An impressive design, perfect configuration management and effective testing strategies are crucial to make the best use of the agility approach.
