Concepts
Working on a single product with multiple teams presents numerous challenges ranging from communication overhead, integration issues, coding standard discrepancies, and timeline inconsistencies. However, all is not lost; there are ways to circumvent these hurdles and still deliver quality products. This article will discuss three notable methods that Developers could adopt to address these challenges.
1. Adopting a Shared Coding Standard:
Abiding by a shared coding standard facilitates uniformity of code across the development teams. This not only makes the code readable and understandable by everyone but also helps detect errors and bugs during code reviews quickly. When the coding style is consistent across the teams, it is easier to integrate and merge the code from different teams into a single product.
For example, in Python coding, PEP8 provides a set of conventions for developers. When developers from different teams are using this coding standard, any member of any team can understand, review, and debug the code, facilitating better cooperation between teams. Regardless of the programming language used, adhering to a commonly agreed-upon coding standard is crucial in multi-team development.
2. Utilizing Continuous Integration (CI) and Continuous Delivery (CD):
CI/CD frameworks help address the challenges of integration, testing, and deployment. Continuous Integration encourages the integration of code into a shared repository frequently, ideally several times a day. Every integration is then verified by an automated build, enabling early detection of integration bugs.
Continuous Delivery extends Continuous Integration by ensuring the codebase is always in a deployable state. It allows all developers from all teams to merge their changes into a shared mainline repository several times a day.
A great example of a CI/CD service is Jenkins. It offers numerous plugins to support building and testing virtually any project, making it an excellent tool for multi-team development.
3. Implementing Agile methodologies and Scrum Framework:
Agile fosters a culture of collaboration and shared accountability, lending itself perfectly to multi-team development. It encourages the timely and efficient resolution of issues, which are inevitable in a multi-team environment. Scrum, an Agile development framework, promotes a self-organizing, cross-functional approach where teams can work on different aspects of the product in an integrated manner.
For instance, in the Scrum daily stand-up meetings, representatives from each team can discuss their progress, the challenges they face, and their plan for the day. These meetings can aid in identifying bottlenecks and resolving them promptly.
| Perks | Example | |
|---|---|---|
| Shared Standard | Facilitates uniformity, easier debugging and integration | PEP8 in Python |
| CI/CD | Frequent integration, early detection of bugs, faster release | Jenkins |
| Agile & Scrum | Collaborative, resolves issues promptly, self-organizing | Daily Stand-ups |
While these methods immensely help when working with multiple teams on one product, it ultimately comes down to the teams’ collaboration, communication, respect for the agreed-upon standards, and commitment towards continuous learning and improvement. Professional certifications like Advanced Certified Scrum Developer (A-CSD) equip the developers not only with a deep understanding of these methodologies and approaches but also play a critical role in enhancing the skill set and efficiency of the developers in handling real-world multi-team projects.
Answer the Questions in Comment Section
True/False: Developers can use the “Scrum of Scrums” method to address challenges associated with multiple teams working on one product.
- True
- False
Answer: True
Explanation: The “Scrum of Scrums” approach creates a wider network to facilitate communication and coordination among different teams. This can help to effectively address challenges that arise when multiple teams are working on the same product.
Which of the following are methods developers could use to address challenges arising when working with multiple teams on one product?
- A. Scrum of Scrums
- B. Agile Chartering
- C. The Waterfall Model
- D. Contract negotiation
Answer: A, B, D
Explanation: Agile Chartering, Scrum of Scrums, and Contract negotiation are methods that could be used. The Waterfall Model, though a project management approach, is not typically used to address challenges associated with multiple teams.
True/False: Context switching is an effective method to handle the challenges that may arise when multiple teams work on a single product.
- True
- False
Answer: False
Explanation: Context switching, or the process of shifting from one task to another, often reduces productivity and accuracy, and isn’t an effective method to handle such challenges.
Which of the following is not a method for addressing challenges when Developers work with multiple teams on one product?
- A. Feature toggles
- B. Championing a blame culture
- C. Work decoupling
- D. Interface contracts
Answer: B
Explanation: A blame culture causes defensiveness, fear, and conflict among teams which is not conducive to tackling challenges. The other options (feature toggles, Work decoupling, Interface contracts) are strategies to mitigate risks and align multiple teams working on one product.
True/False: Introducing interface contracts between teams can improve communication and coordination when multiple teams are working on one product.
- True
- False
Answer: True
Explanation: Interface contracts define how different software components will interact, which can reduce the likelihood of misunderstandings and conflicts between teams.
Single select: Which of the following is the least suitable method for Developers to address challenges when working with multiple teams on one product?
- A. Agile Chartering
- B. Scrum of Scrums
- C. Working in silos
- D. Using feature toggles
Answer: C
Explanation: Working in silos undermines cross-team collaboration, which can lead to inconsistencies and miscommunication, thereby exacerbating challenges when multiple teams are working on the same product.
True/False: Agile Chartering involves creating a physical or digital charter to visualize the project’s timeline, activities, and dependencies, which can address challenges when multiple teams are working on one product.
- True
- False
Answer: True
Explanation: Agile Chartering provides a shared vision and objectives for all the teams involved, which helps to align them and reduce potential misconceptions or conflicts.
Feature toggles can’t be used to manage challenges of working with multiple teams on a single product.
- True
- False
Answer: False
Explanation: Feature toggles can be reliably used to manage different aspects of a product being delivered by various teams, enabling seamless integration and reducing risks.
Contract negotiation is a relevant strategy for managing challenges arising from multiple teams working on a product. True or False?
- True
- False
Answer: True
Explanation: Contract negotiation can define the terms of inter-team dependencies, clear role expectation and help to prevent misunderstanding, thereby eliminating potential problems.
The method where teams work independently and integrate their changes regularly to the main branch is called:
- A. Scrum of Scrums
- B. Work decoupling
- C. Continuous Integration
- D. Lean Programming
Answer: C
Explanation: Continuous Integration is a DevOps practice where developers regularly merge their changes to the main branch, ensuring team’s work is integrated regularly and can detect problems early.
One method developers could use is establishing a clear communication plan. This would ensure everyone is on the same page and reduce misunderstandings.
Thanks for the useful blog post!
Developers can use version control systems like Git to manage code changes efficiently across multiple teams.
Great post on tackling inter-team challenges!
Using a microservices architecture can also be an effective method. It allows teams to work on separate components independently.
Appreciate the insights provided in this post.
I think adopting a shared vision through documentation also helps bind multiple teams together.
Useful post for Advanced Certified Scrum Developer exam prep!
