Facing a complex engineering challenge? – Use a Spike!

In agile software development, a spike is a time-boxed investigation into a specific technical issue or problem. The goal of a spike is to gather information and explore possible solutions to the issue, in order to provide the team with a better understanding of the problem and potential approaches to addressing it.

Spikes are typically used when the team is facing an uncertain or complex technical challenge, and needs more information in order to make informed decisions about how to proceed. For example, a spike might be used to explore a new technology or approach, or to conduct a proof of concept for a particular solution.

To use a spike, the team first identifies the specific technical issue or challenge that they are facing. The team then sets a time box for the spike, typically ranging from a few hours to a few days, depending on the complexity and scope of the issue. During the spike, the team members who are working on the spike focus exclusively on exploring the issue and gathering information, without being interrupted by other work.

At the end of the spike, the team reviews the information and insights that have been gathered, and uses this information to make informed decisions about how to proceed. This may involve selecting a specific solution to implement, or deciding to conduct additional spikes to explore other options.

Spikes are a valuable tool for agile teams that are facing complex or uncertain technical challenges. By providing a focused and time-boxed investigation into these challenges, spikes can help teams to gather the information and insights they need to make informed decisions and move forward with confidence.

When does manual testing still provide value?

Manual testing is still required for software in some cases, even when automated testing tools are available. There are several situations where manual testing may be necessary, including the following:

Exploratory testing:
Manual testing can be useful for exploratory testing, where the goal is to test the software in an unstructured and open-ended manner. This can help to identify unexpected or hidden issues with the software, and can provide valuable insights into its behavior and functionality.
Usability testing:
Manual testing can also be useful for usability testing, where the goal is to evaluate the user experience of the software. This can involve testing the software with real users, and observing how they interact with the software in order to identify areas for improvement.
Regression testing:
In some cases, manual testing may be necessary for regression testing, where the goal is to ensure that changes to the software have not introduced new bugs or issues. This can be particularly important when changes to the software have a significant impact on its behavior or functionality, and automated testing may not be able to adequately cover all scenarios.

While automated testing can be a valuable tool for software development, there are still some situations where manual testing is necessary. By considering the specific needs and circumstances of the project, teams can determine when manual testing is required, and can use it effectively to improve the quality and functionality of the software.

Do you know how to Toggle?

Toggles, also known as feature flags or feature switches, can help agile teams in several ways. First, they allow teams to quickly and easily enable or disable specific features or functionality without having to do a full deployment. This can be useful for testing new features or for rolling back changes that cause problems.

Second, toggles can help teams experiment and test different variations of a feature to see which one performs best. This can be done through A/B testing, where different versions of a feature are shown to different users, and the team can then analyze the results to determine which version is most effective.

Third, toggles can help teams manage the deployment of complex features that may take a long time to develop and test. By using toggles, teams can gradually roll out the feature to a small group of users, monitor its performance, and then gradually expand its use to more users. This can help teams avoid the risks associated with deploying a complex feature to all users at once.

Toggles can help agile teams be more flexible and responsive to changing needs, and can make it easier to test and deploy new features and functionality.

Coping with change control in an agile environment

Control boards and change approval boards are processes that are used to review and approve changes to a project or product. In an agile environment, these processes can slow down the development and deployment of new features and functionality because they add an additional layer of review and approval that must be completed before a change can be made.

To address this, teams can take a number of steps to streamline control boards and change approval boards without sacrificing the benefits of having a review and approval process in place. For example, teams can:

Set clear criteria for what types of changes require review and approval, and which ones can be made without going through the control board or change approval board.
Use automated tools to help manage the review and approval process, which can speed up the flow of information and reduce the need for face-to-face meetings.
Establish clear roles and responsibilities for members of the control board or change approval board, and ensure that they have the necessary training and support to do their jobs effectively.
Regularly review and evaluate the effectiveness of the control board or change approval board, and make changes as needed to improve their efficiency and effectiveness.

It is important for teams to strike a balance between the need for review and approval processes and the need for agility and speed in an agile environment. By taking a proactive and thoughtful approach to managing control boards and change approval boards, teams can minimize their impact on agile development without sacrificing the benefits they provide.

6 Easy steps to replace your monolith incrementally

Here are some tips for replacing your monolith incrementally:

Start by identifying the parts of your monolith that can be replaced first. This could be a standalone component or a group of related components that can be extracted and replaced without disrupting the rest of the monolith.
Create a plan for how you will extract and replace the selected components. This should include details about the technologies and approaches you will use, as well as any dependencies or challenges you may encounter.
Communicate your plan to the rest of your organization and get buy-in from key stakeholders. This will help ensure that everyone is on board and understands the implications of the changes you’re making.
Begin extracting and replacing the selected components according to your plan. This should be done carefully and incrementally, to minimize disruption and ensure that the monolith continues to function properly during the transition.
Monitor and test the extracted components to ensure they are functioning properly and meeting the organization’s needs. This will help you identify any issues or challenges that need to be addressed before proceeding with the next phase of the replacement.
Continue extracting and replacing components until the entire monolith has been replaced. This may take some time, depending on the size and complexity of your monolith, but the end result will be a more modular, scalable, and maintainable system.

By following these steps, you can replace your monolith incrementally and minimize the disruption and risk associated with such a major change. This will help ensure a successful transition and enable your organization to reap the benefits of a more modular, agile architecture.

Have you implemented continuous testing?

In the Agile software development approach, continuous testing is the practice of integrating testing activities into the development process in a way that allows teams to identify and fix defects as early as possible in the development lifecycle. This approach helps teams to deliver high-quality software faster and with fewer defects, as testing is integrated into the development process rather than being treated as a separate phase.

Continuous testing typically involves the use of automated testing tools and techniques, such as unit tests, integration tests, and functional tests, to ensure that the software is working as intended at all times. This can include running tests continuously in the background as code is being developed, as well as running tests before and after code is deployed to production.

One key benefit of continuous testing is that it helps teams to catch defects early in the development process, when they are easier and less expensive to fix. This can significantly reduce the time and effort required to fix defects, and it can also help to improve the overall quality of the software. Additionally, by integrating testing into the development process, teams can get faster feedback on the quality of their software, which can help them to identify and address issues more quickly.

Heat Mapping – where is your software system fragile?

Heat mapping is a technique that can be used to visually represent the distribution and intensity of defects in a software system. This is typically done by creating a heat map that represents different parts of the system using different colors, with warmer colors indicating a higher concentration of defects.

Heat mapping engineering defects can help in a number of ways. First, it can provide a visual representation of the distribution and intensity of defects in the system, which can help teams to identify areas of the system that may be more prone to defects. This can be particularly useful for identifying patterns or trends that may not be immediately apparent from looking at individual defects.

Second, heat mapping can help teams to prioritize their efforts by identifying areas of the system that are most in need of attention. For example, if a particular component of the system has a high concentration of defects, it may be a good candidate for further investigation or refactoring.

Finally, heat mapping can help teams to track the progress of their efforts to reduce defects over time. By comparing heat maps from different points in time, teams can see if their efforts are having the desired impact and make adjustments as needed.

Addressing Software Fragility

In software development, “fragility” refers to the susceptibility of a system to break or malfunction when changes are made to it. A fragile system is one that is prone to unexpected errors or failures when modifications are made, even if those changes are minor or unrelated to the parts of the system that are breaking.

Fragility can be caused by a variety of factors, including poor design, a lack of testing, and a lack of separation between different components of the system. It can also be caused by a lack of modularity, where changes to one part of the system have unintended consequences on other parts of the system.

To address fragility in software, it is important to design systems with modularity and separation of concerns in mind, and to thoroughly test the system to ensure that it is robust and can withstand changes. It is also important to continuously monitor and maintain the system to identify and fix any potential issues that may arise.

Long-term application supportability

There are several reasons why software systems can become difficult to support over time. Some common reasons include:

Lack of documentation:

If the software system was not well-documented, it can be difficult for support staff to understand how the system works and how to troubleshoot problems.

Complexity:

Complex software systems can be more difficult to support because they may have many different components and integrations, making it harder to identify and fix issues.

Outdated technology:

As technology advances, software systems that rely on older technologies may become more difficult to support because the necessary skills and resources may no longer be readily available.

Customization:

Customized software systems can be more difficult to support because they may be unique and not well-understood by support staff.

Poor quality:

Poorly-designed or implemented software systems can be more difficult to support because they may be prone to errors and glitches, making it harder to identify and fix issues.

It’s important for organizations to carefully consider the long-term supportability of software systems when choosing and implementing them, in order to minimize the difficulties and costs associated with supporting them over time.

Get specific about NFRs

Non-functional requirements (NFRs) are software requirements that specify how a system should behave, rather than what it should do. They describe the system’s quality attributes, such as reliability, performance, security, and usability. Here are some examples of non-functional requirements for software:

1. Performance

This includes requirements related to the speed, efficiency, and scalability of the system. Examples might include response time goals for specific actions, the maximum number of users the system can handle, and the ability to scale up or down as needed.

2. Security

These are requirements related to protecting the system and its data from unauthorized access or tampering. Examples might include requirements for encryption, authentication, and access control.

3. Usability

These are requirements related to the ease of use and understandability of the system. Examples might include requirements for user-friendly interfaces, clear error messages, and the ability to easily navigate the system.

4. Reliability

These are requirements related to the stability and dependability of the system. Examples might include requirements for uptime, the ability to recover from errors or failures, and the ability to handle unexpected input or conditions.

5. Maintainability

These are requirements related to the ease of maintaining and updating the system over time. Examples might include requirements for clear documentation, modular design, and the ability to easily test and deploy changes.

Non-functional requirements are important because they ensure that the system meets the quality standards that are necessary for it to be effective and usable.

DevOps is the Backbone of Agile

DevOps is a set of practices that aims to improve collaboration and communication between software development and operations teams, with the goal of delivering software more frequently and reliably. It is often considered the backbone of agile because it supports and enables the principles and practices of agile development.

One of the key benefits of DevOps is the ability to deliver software quickly and frequently, which is a key aspect of agile development. By automating many of the processes involved in software delivery, DevOps enables teams to iterate and deploy code faster, which allows for faster feedback and the ability to respond to changing business needs.

In addition, DevOps promotes a culture of collaboration and continuous improvement, which is essential for agile teams. By bringing development and operations teams together and fostering a culture of continuous learning, DevOps helps teams to identify and eliminate bottlenecks, improve efficiency, and deliver value to customers more quickly.

DevOps is a key aspect of agile development because it enables teams to deliver software faster, more reliably, and with higher quality, which is essential for organizations that are looking to respond to changing business needs in a flexible and efficient manner.

Help your application support team establish classes of service

An application support team could use classes of service to prioritize and manage the work that they do. By establishing different classes of service, the team can ensure that they are focusing their efforts on the most important and urgent tasks first, while still addressing lower-priority tasks as time allows.

To use classes of service, the application support team would need to define the criteria for each class of service, such as the severity of the issue, the impact on users, or the urgency of the request. They could then use these criteria to assign incoming requests to the appropriate class of service.

For example, the team might define a “critical” class of service for issues that are preventing users from accessing the application, a “high” class of service for issues that are impacting a large number of users or have a significant impact on business operations, and a “low” class of service for issues that are minor or have a limited impact on users.

The team could use different visual indicators, such as different colors or shapes of cards or stickers, to represent the different classes of service and help them prioritize their work. They might also use a kanban board or other tool to visualize and manage the work in their workflow.

Using classes of service can help the application support team to be more efficient and effective in their work, by ensuring that they are addressing the most important issues first and providing a clear understanding of the priority of each task.
