Cumulative Flow is a visual representation of the flow of work items, such as user stories, tasks, or features, as they move through various stages in a project. It provides a dynamic chart that illustrates the rate at which work is added, completed, and remains in progress over time. Cumulative Flow diagrams typically have a time axis (horizontal) and a count axis (vertical) representing the number of work items.

The diagram’s main components include:

Backlog: The initial phase where work items are added to the project.
In Progress: The phase where work items are actively being worked on.
Done: The phase where completed work items are marked as done and ready for delivery.

Key Principles of Cumulative Flow

Understanding Cumulative Flow is guided by several key principles:

Visualization: Cumulative Flow visualizes the flow of work items, making it easy to spot trends, variations, and potential issues.
WIP Limits: Work in progress (WIP) limits are often applied to control the number of work items in the “In Progress” phase, preventing overloading and bottlenecks.
Cycle Time: Cycle time, the time it takes for a work item to move from “In Progress” to “Done,” is an essential metric derived from Cumulative Flow.

Creating and Interpreting Cumulative Flow Diagrams

Creating a Cumulative Flow Diagram

Creating a Cumulative Flow Diagram involves the following steps:

Data Collection: Gather data on work items, their start and end dates, and the current status of each item.
Data Entry: Input the data into a spreadsheet or a dedicated tool that supports Cumulative Flow chart creation.
Chart Configuration: Configure the chart to include the necessary phases, such as “Backlog,” “In Progress,” and “Done.” Set the time axis and count axis appropriately.
Plotting Data: Plot the data points on the chart, indicating the number of work items in each phase at different time intervals.

Interpreting a Cumulative Flow Diagram

Interpreting a Cumulative Flow Diagram involves the following key aspects:

Work Item Trends: Observe how the lines representing different phases (e.g., “Backlog,” “In Progress,” “Done”) fluctuate over time. A rising “In Progress” line may indicate a bottleneck, while a stable “Done” line suggests a steady completion rate.
WIP Limit Violations: Identify instances where the “In Progress” line exceeds the set WIP limit. This signifies a potential bottleneck or resource constraint.
Cycle Time Analysis: Calculate cycle times by tracking the time it takes for work items to move from “In Progress” to “Done.” Analyze cycle time trends and variations.
Identifying Patterns: Look for patterns, such as recurring spikes or plateaus, which may reveal issues or trends in the project’s workflow.
Bottleneck Detection: Bottlenecks are often represented by a widening gap between the “Backlog” and “In Progress” lines. Identifying bottlenecks helps in taking corrective actions.

Benefits and Importance of Cumulative Flow

Cumulative Flow offers numerous benefits and holds great importance in agile project management:

1. Real-Time Visibility

Cumulative Flow provides real-time visibility into a project’s workflow, allowing teams to monitor progress and make informed decisions.

Connected Agile & Lean Frameworks

AIOps

AIOps is the application of artificial intelligence to IT operations. It has become particularly useful for modern IT management in hybridized, distributed, and dynamic environments. AIOps has become a key operational component of modern digital-based organizations, built around software and algorithms.

AgileSHIFT

AgileSHIFT is a framework that prepares individuals for transformational change by creating a culture of agility.

Agile Methodology

Agile started as a lightweight development method compared to heavyweight software development, which is the core paradigm of the previous decades of software development. By 2001 the Manifesto for Agile Software Development was born as a set of principles that defined the new paradigm for software development as a continuous iteration. This would also influence the way of doing business.

Agile Program Management

Agile Program Management is a means of managing, planning, and coordinating interrelated work in such a way that value delivery is emphasized for all key stakeholders. Agile Program Management (AgilePgM) is a disciplined yet flexible agile approach to managing transformational change within an organization.

Agile Project Management

Agile project management (APM) is a strategy that breaks large projects into smaller, more manageable tasks. In the APM methodology, each project is completed in small sections – often referred to as iterations. Each iteration is completed according to its project life cycle, beginning with the initial design and progressing to testing and then quality assurance.

Agile Modeling

Agile Modeling (AM) is a methodology for modeling and documenting software-based systems. Agile Modeling is critical to the rapid and continuous delivery of software. It is a collection of values, principles, and practices that guide effective, lightweight software modeling.

Agile Business Analysis

Agile Business Analysis (AgileBA) is certification in the form of guidance and training for business analysts seeking to work in agile environments. To support this shift, AgileBA also helps the business analyst relate Agile projects to a wider organizational mission or strategy. To ensure that analysts have the necessary skills and expertise, AgileBA certification was developed.

Agile Leadership

Agile leadership is the embodiment of agile manifesto principles by a manager or management team. Agile leadership impacts two important levels of a business. The structural level defines the roles, responsibilities, and key performance indicators. The behavioral level describes the actions leaders exhibit to others based on agile principles.

Andon System

The andon system alerts managerial, maintenance, or other staff of a production process problem. The alert itself can be activated manually with a button or pull cord, but it can also be activated automatically by production equipment. Most Andon boards utilize three colored lights similar to a traffic signal: green (no errors), yellow or amber (problem identified, or quality check needed), and red (production stopped due to unidentified issue).

Bimodal Portfolio Management

Bimodal Portfolio Management (BimodalPfM) helps an organization manage both agile and traditional portfolios concurrently. Bimodal Portfolio Management – sometimes referred to as bimodal development – was coined by research and advisory company Gartner. The firm argued that many agile organizations still needed to run some aspects of their operations using traditional delivery models.

Business Innovation Matrix

Business innovation is about creating new opportunities for an organization to reinvent its core offerings, revenue streams, and enhance the value proposition for existing or new customers, thus renewing its whole business model. Business innovation springs by understanding the structure of the market, thus adapting or anticipating those changes.

Business Model Innovation

Business model innovation is about increasing the success of an organization with existing products and technologies by crafting a compelling value proposition able to propel a new business model to scale up customers and create a lasting competitive advantage. And it all starts by mastering the key customers.

Constructive Disruption

A consumer brand company like Procter & Gamble (P&G) defines “Constructive Disruption” as: a willingness to change, adapt, and create new trends and technologies that will shape our industry for the future. According to P&G, it moves around four pillars: lean innovation, brand building, supply chain, and digitalization & data analytics.

Continuous Innovation

That is a process that requires a continuous feedback loop to develop a valuable product and build a viable business model. Continuous innovation is a mindset where products and services are designed and delivered to tune them around the customers’ problem and not the technical solution of its founders.

Design Sprint

A design sprint is a proven five-day process where critical business questions are answered through speedy design and prototyping, focusing on the end-user. A design sprint starts with a weekly challenge that should finish with a prototype, test at the end, and therefore a lesson learned to be iterated.
