Avoiding Nightmares During the Handover

At the end of a project, the transfer of authority and control from one group to another is known as a handover. This is an integral part of the process for developing new software and must be carefully planned and executed in order to guarantee a successful conclusion to the project.

As software developers, much of our work involves collaborating on different teams and projects. To ensure we are able to work efficiently and effectively, it is essential to have an effective onboarding process in place. This process can be time-consuming and may present some challenges if not managed carefully. Therefore, it is important to take the necessary steps to ensure a smooth transition and integration into a new team or project.

These components consist of:

  • The project and its infrastructure are documented.
  • Project-related accounts and subscriptions.
  • Rules and regulations for the product, etc.

As engineers, we often dedicate a great deal of our efforts to the creation of new features and the enhancement of existing ones, without taking into consideration the ramifications of a potential handover in the future. This lack of foresight can lead to a challenging, and oftentimes undesirable, handover experience.

As a DevOps Engineer, I recently had the responsibility of overseeing a handover process, and I have been giving considerable consideration to the topic. My goal was to act as a facilitator to ensure a smooth transition with minimal disruptions. Unfortunately, there were some issues that could have been averted if the handover had been addressed earlier in the project.

In order to ensure a successful transition, I would like to provide you with some of the insights I have gained throughout this handover process and how they should be incorporated from the beginning of the development process. By doing so, I believe it will ensure a smoother and more efficient transfer.

Just keep it basic

As product scope increases, software architecture may become increasingly complex. Although this is an unavoidable result in some situations, it is important for engineers to make every effort to keep these complexities to a minimum.

It’s easy to overcomplicate anything; true innovation is in finding ways to make something really complex seem easy. – Charles Mingus

Overengineering can be detrimental to the success of a project, as it can cause an unnecessary expenditure of both time and money. If the scope of a project is starting to get out of control, it is advisable to divide it into more reasonable sections. Rather than attempting to reinvent the wheel, existing services or Application Programming Interfaces (APIs) can be utilized to assist in the development of the desired product.

When it comes to hosting and financial considerations for video conversations, it may be tempting to create your own service; however, this is not the most prudent choice. Alternatives such as Twilio or Google Hangouts already exist and have already been tested, meaning that you would save a significant amount of time, money, and effort by opting for one of these existing services. Ultimately, the second option is the more rational decision.

It’s important to keep detailed records on everything.

Software developers consistently emphasize the importance of comprehensive documentation. Generally, it is less challenging to comprehend and maintain a project if it has been thoroughly documented.

Without sufficient documentation, a new developer can quickly become overwhelmed when presented with a intricate codebase. It is unreasonable to assume that everyone will be able to interpret the thoughts of the original developer. Even experienced coders can struggle to understand their own code if it is not documented properly or the variable and function names are not self-explanatory. With proper documentation and descriptive variable and function names, it is much easier for a developer to navigate the codebase and identify and rectify any bugs.

It’s getting difficult to gain approval due to a lack of paperwork. – Wietse Venema

Working without documentation for a codebase is like being handed a raft with no compass and given an arbitrary deadline to reach land. To avoid this daunting task, it is essential to create a well-documented and organized codebase that is easy to understand. This will enable developers to quickly and efficiently identify and resolve any issues that may arise.

It is strongly recommended that any supplementary services you are utilizing should be included in your records. This will enable the new team assigned to the project to make modifications with a comprehensive understanding of any interdependent components that might be necessary.

Put into practise efficient methods of working and current standards.

Adhering to best practices and established procedures is essential for any programmer who uses a particular language or framework. Doing so serves both the purpose of enhancing efficiency and simplifying maintenance efforts. In order to ensure the consistent use of certain technologies, these procedures have been developed and are widely accepted.

Adhering to the processes and guidelines advocated by the development community can make it much easier for other developers to comprehend and collaborate on your codebase. While it is sometimes necessary to think outside the box when tackling a project, it is also important to ensure that the process is documented and remains consistent. This will ensure that all individuals involved in the project are able to work together efficiently.

It is essential that a clear set of rules and regulations be established and strictly adhered to from the outset of the development process through to the conclusion of deployment. This will guarantee excellent results as well as facilitate cooperative collaboration between all team members throughout the entire project.

It is recommended to utilize best practices in order to ensure that only high-quality code is released to users and that any required updates will not cause considerable interruptions in service. Adopting best practices will guarantee that users are provided with the most secure, reliable, and effective code. Additionally, it will minimize the chances of major disruptions to service when updates are necessary.

Make use of a “wall of separation”

Separation of Concerns (SOC) is a design concept in the field of computer science which promotes dividing a programme into discrete units that each address a separate issue. This approach allows for the development of a comprehensive system that is more easily maintained and modified as the requirements of the programme evolve.

As part of the regular development process of applications, this method will enable teams to divide the complicated tasks in an efficient manner, thus making it easier to manage the applications. This will result in smoother operation and no conflicts between teams.

Microservice architecture is an excellent example of the concept of separation of concerns, wherein a monolithic program is divided into smaller, independent components that can be combined to form a fully functional software system. An excellent illustration of this concept in practice is Django applications, which are written in the Python programming language.

The separation of concerns is highly beneficial when it comes to application hosting infrastructure. It is recommended that production funds be kept separate from research and development funds in order to eliminate the risk of contamination in the production environment, while also streamlining the management of both areas. This approach not only reduces risks, but also simplifies the administrative burden associated with managing both production and development funds.

Don’t use your own login info or accounts.

Nowadays, it is essential for any professional, but especially a DevOps Engineer, to practice continuous integration. We consider experimenting with various technologies related to monitoring, logging, deployment, testing, etc. to be of utmost importance, and in many cases, multiple accounts may need to be created if the service is not able to be hosted independently.

In general, we leverage a single account for all of our projects in order to prevent any issues from arising. This approach has its advantages, such as the centralized dashboard which allows for easier management; however, it can be less efficient when it comes to transitioning the projects to other parties.

Heroku provides a service that enables users to migrate their accounts. Unfortunately, this option is not available to everyone, meaning that they will have to go through the tedious and time-consuming process of creating new accounts and making the necessary adjustments to their associated services.

It is recommended that individual accounts be created for each project to avoid potential issues. By keeping credentials secure in digital vaults such as LastPass, it is easy to assign responsibility for individual accounts to team leaders or technical officers by simply providing them access to the necessary folders containing the credentials.

Try to automate as much as possible.

In today’s world, applications are increasingly reliant on a range of external services to keep them running smoothly. While manual maintenance of these services may be possible, it can often be a laborious and tedious task. Amazon Web Services (AWS) is a prime example of this, offering a variety of software development services that can be provisioned manually if necessary. However, this approach can be problematic in instances when the infrastructure suffers from failure or corruption, as it can be difficult to replicate the same environment, resulting in downtime and loss of productivity.

Amazon Web Services (AWS) has developed fantastic instruments that facilitate service provisioning using a configuration method, such as CloudFormation is a powerful service offered by Amazon Web Services that enables users to create and manage their cloud infrastructure as code. Leveraging Infrastructure as Code (IaC) techniques, users can easily create and manage production, development, and staging environments by executing scripts and commands. Moreover, the cloud service provider community has developed tools based on CloudFormation that further simplify infrastructure versioning and rollback.

Among the resources available to you are the following:

  • Ansible
  • SparkleFormation
  • Terraform
  • Chef
  • Puppet

Unfortunately, I must forewarn you: once you decide to automate anything, there is no going back.

And finally:

Produce high-quality code.

My colleagues and I often make the humorous comparison that writing code is comparable to writing poetry; it should be crafted with the purpose of impressing the computer. It should be clear and straightforward, and should have a structure that is easy to interpret.

Consider the reader of your code to be a psychopath who is aware of your whereabouts. – Unknown

In order to make handoffs as effortless as possible for both you and your team, it is essential to think ahead and design your applications with handoffs in mind from the outset. Below are some options to consider that can assist in this process: – Create an efficient system for communication between team members. – Utilize a shared project management system so that everyone is on the same page. – Implement a standardized development process. – Invest in the proper tools and technologies to ensure smooth handoffs. – Document all processes to ensure consistency. – Utilize automated testing to ensure quality.
