DevOps is one of those concepts that everyone talks about but very few understand completely or are able to implement it. As opposed to a tool or methodology, it is more of a culture that organisations can imbibe and incorporate between development and operations within a team. It involves a high degree of collaboration across roles focusing on the business than on departmental objectives.
Few misconceptions about DevOps culture are like, it’s a particular toolkit or software product, or it is about changing processes. It’s not. Instead, it’s based on trust, and high value placed on learning through experimentation.
However, questions usually arise, what are the common mistakes made by the team while trying to adopt DevOps culture? What are the modes of successful integration and adoption?
Let’s start from the beginning.
History of DevOps
When IT operations and software development communities started outbursting about the fatal level of dysfunction in the industry, the birth of DevOps movement was marked around 2008. The organisational and functional gap between the coding and deployment team as per the traditional model was in question and railed against.
As the operations of the team were separated by objectives, leadership and performance indicators, it resulted in long hours, rushed releases, and unhappy customers. The leaders in the industry recognised the pattern and took a step in the direction of DevOps. But DevOps isn’t some magic that can transform your business overnight. It starts with small, incremental changes with which your team can embark upon the DevOps journey. However, it’s easier said than done. Explore the mistakes that you are making and what are those changes.
Common Mistakes Your DevOps Team is Making
Even when a team is working towards a shared goal, there are challenges and barriers that can lead to these common mistakes:
While attempting to complete urgent deliveries, organisations ignore the lack of experience and knowledge of DevOps among the employees who struggle to produce outcomes. This results in low quality output and in turn affects struggle to keep up with the competition in the market.
Being a DevOps professional, you shouldn’t be rushing to get the job done and meet tight schedules only. The security issues and bugs that can come at a later stage should be thought for during the process of production.
It’s always advised to start small and it seems right to be following it in the very beginning. However, when it comes to adopting the DevOps culture, it shouldn’t mean that you stay small moving forward too. For example, not deploying at a higher frequency can lead to more issues as the right processes are not in place for optimised activities. Companies might experience factors like, higher costs, lower customer satisfaction, time taking developments, slower growth if they don’t utilise the DevOps methods more regularly.
The Old and the New
While adopting the DevOps culture, companies shouldn’t let go of the old practices and personnel. This model known as ‘Hybrid DevOps’, streamlines some parts of the processes whereas other parts can be continued at the traditional pace. However, the Hybrid model can backfire for the organisation as newer methods of working cannot always coexist with the age-old practices and might lead to disruptions and clashes between the teams. Thus, you need to check if they can or cannot coexist for your organisation or team.
It’s an organisational myth that DevOps processes and tools doesn’t need constant monitoring and overseeing. The role of DevOps engineers shouldn’t end with the release of the application or software. It is an absolute must to ensure constant availability of resources, goals, and budgets for smooth and continuous functioning of the software. A plan that never quits learning at any stage or hinders improvement along the way, is a perfect DevOps plan in the making.
Overcome Challenges to Get Your Team to the Other Side
Centred around collaborations and harnessed by culture, let’s explore the fundamental core of DevOps culture:
Learn to Say ‘No’
The first rule of eliminating roadblocks is by starting to say ‘’no’’ to anything that doesn’t add value to your work or business and should be the most important behaviour adopted by all. It preserves credibility, develops trust and spreads a clear message across about your values and standards of working. Having the ability to choose wisely and prioritise ruthlessly is the next thing that comes along with it. A delivery with flawless but unnecessary features is more of a failure for both the customers and the DevOps team.
The team should ensure that each member has a clear vision and is 100% ready to achieve the desired outcomes before committing on any project or task. Having an acceptance criteria of your work gives a sense of responsibility for its success and allows you to go all in on the chosen field. From small deliveries to completing bigger assignments, commitment adds customer value and invite accountability for customer satisfaction which is the ultimate measure of success.
Choosing DevOps isn’t a sure shot jackpot to success unless you accept that failures are a part of all process and a big learning in the end. Not always will you meet your own expectations along with those of your customers. However, picking up from where you fall, learning from the mistakes and moving on towards improvement is the key to adaptability. Organisations should welcome the changes as per requirements that can help in quick adaptation and frequent deliveries.
The above results by the Statistics portal, Statista, shows the extent to which developers worldwide have adopted DevOps in their workplace, in 2017 and 2018.
Organisations can start from building DevOps culture and teams within and initiate the process of identifying talent internally that can be trained for DevOps instead of hiring an entirely new team. As an already existing employee has a background knowledge of the company, the only investment is to align the DevOps changes with the organisational values and goals.
Regularity in Meetings
When a company implements the DevOps culture and tools, the team is impacted personally and professionally in terms of the working processes. Therefore, organising regular meetings with each member or entire teams can be a healthy way to ensure an effective implementation of the changes that are in the initial phase. It also becomes an affirmative way to strengthen the workforce and their technical skills.
Organisations should keep in mind that not every employee in the team comes with an IT background necessarily. Thus, organising or encouraging employees to attend industry conferences and meetups on DevOps and its related topics can give a better perspective about its objectives in the long run.
Sharing is Caring
When DevOps is employed among teams, you become a part of a larger community of like-minded individuals. The collective commitment of the group towards delivering quick customer satisfaction and building a better organisation brings out the desired outcomes. Thus, you should share your best and successful practices with others that can improve the pace and quality around you. The solicit expertise from your end can help others and in turn give remarkable effects to you in the process too.
Select the Right Tools
Lastly, DevOps culture and processes are incomplete without effective tools and applications in the projects. Organisations should invest in smart, new and advanced tools that are crucial to the implementation along with keeping the members interested in the process.
Let’s explore few such tools that can be adopted for best of practices in your organisation.
