Modeling in Color

5 minutes 5 Questions

Modeling in Color is a technique used in FDD for visualizing and documenting domain models. This approach uses four colors to represent different aspects of the model: pink for Moment-Interval, yellow for Role, green for Party-Place-Thing and blue for Description. Each one has a different semantic …

Modeling in Color Guide & Exam Tips

What is Modeling in Color:
Modeling in Color is a technique used in Feature Driven Development (FDD), an agile project management methodology. It focuses on creating a system of color-coded models, each representing a different aspect or entity of a project. This allows teams to visually represent and understand complex systems in a simplified and intuitive manner.

Why is it Important:
Modeling in Color is important as it provides a unified language to express complex ideas, making them easier to understand and align. This simplifies collaboration, problem-solving, and decision-making within the team. It also enables the easy identification of potential issues and dependencies.

How it Works:
Each color represents a different domain thing such as person, place, event, and role. These 'things' are mapped to a color (usually four colors) allowing teams to visually represent their system or process. Each color-coded model often consists of classes and interactions that depict scenarios within the domain.

Exam Tips: Answering Questions on Modeling in Color:
1. Understand the purpose: Knowing why and how Modeling in Color is used can help deduce the correct answers.
2. Know the colors and their corresponding domain 'things': This can help answer questions about the application and interpretation of color-coded models.
3. Apply scenario-based thinking: Many exam questions may present a scenario and ask you to apply the Modeling in Color technique. Remember the colors and their meanings to decide the best approach for the circumstances given in the question.

PMI-ACP - Modeling in Color Example Questions

Test your knowledge of Modeling in Color

Question 1

During a Modeling in Color session with your Agile team for a new software project, a crucial stakeholder insists on adding a new color to the primary color spectrum to represent a job role that doesn't exist in traditional modeling. How should this be handled?

Add the new color to appease the stakeholder without considering the consequences. Abruptly reject the suggestion as it deviates from the norm. Ignore the suggestion and proceed without addressing the issue. Politely explain that the modeling in color scheme is standardized and adding a new color could lead to confusion and inconsistencies.

Correct Answer: Politely explain that the modeling in color scheme is standardized and adding a new color could lead to confusion and inconsistencies.

In a Modeling in Color session, colors are predetermined to symbolize certain aspects of the model. This standardization helps the team follow a consistent approach, ensuring everyone understands the model in the same way. Adding a new color to represent a non-traditional job role could lead to confusion and misunderstandings, as this break from the norm may not be universally understood. It's best to communicate this politely to key stakeholders. Abruptly rejecting the suggestion does not encourage an open, collaborative environment. Adding the new color without considering potential implications can lead to confusion and miscommunication. And finally, ignoring the suggestion without addressing the issue not only dismisses the stakeholder's input but could also lead to unresolved issues in the model.

Question 2

In a project using Modeling in Color, one team member consistently proposes solutions that fall out of the agreed color spectrum, disturbing the uniformity of the model. What approach should you take?

Dismiss the team member's proposals without any explanation. Silently correct the team member's proposals without bringing the issue to their attention. Address the issue openly with the team member, reinforcing the importance of adhering to the Modeling in Color spectrum for consistency. Allow the team member to continue with their proposals, assuming others will correct it later.

Correct Answer: Address the issue openly with the team member, reinforcing the importance of adhering to the Modeling in Color spectrum for consistency.

The best approach in case a team member consistently proposes solutions that fall out of the agreed color spectrum, disturbing the uniformity of the model in a project using Modeling in Color, is to address the issue openly with the team member, reinforcing the importance of adhering to the Modeling in Color spectrum for consistency. This allows the team member to understand the issue at hand and gives them a chance to correct their approach. Dismissing the team member's proposals without any explanation does not help them understand the problem and improve. Silently correcting the proposals also does not provide the necessary feedback for the member to learn and improve. While allowing the team member to continue with their proposals, assuming others will correct it later may seem like an easy option, it can lead to confusion and inefficiency in the project. Therefore it is not the recommended approach.

Question 3

While using Modeling in Color, your Agile team encounters an issue where the formed model seems overly complex and hard to understand. How should you tackle this problem?

Refactor the model, breaking down complex elements into simpler ones ensuring they still adhere to the Modeling in Color spectrum. Ignore the complexity, assuming that it will be dealt with during the implementation phase. Add new colors to simplify the model. Completely discard the model and start again from scratch without considering the problematic elements.

Correct Answer: Refactor the model, breaking down complex elements into simpler ones ensuring they still adhere to the Modeling in Color spectrum.

The most effective way to tackle an overly complex model while using Modeling in Color in Agile is to refactor the model - this involves breaking down the complex elements into simpler ones while ensuring that they still adhere to the Modeling in Color spectrum. This approach is beneficial as it aims to reduce the complexity while preserving the essence of the model. On the other hand, ignoring the complexity under the assumption that it will be addressed during the implementation phase is not effective, as it may lead to future complications and miscommunications in the team. Adding new colors to simplify the model also fails to address the root cause of the complexity. Moreover, discarding the model and starting from scratch without considering the problematic elements is a drastic action that could potentially waste the valuable resources and time invested in the initial model, making it the least recommended choice.
