In an era where climate change is one of the main challenges for our future, it is crucial for companies to apply favorable environmental practices. Customers look for eco-friendly businesses and employees want to work for ethical companies.
At the same time as companies embark on their sustainable journeys, data analytics is emerging as a transformative force in business. Both concepts may seem to have nothing in common, but there has been an increasing number of organizations applying big data to improve their sustainability. Data analytics allows companies to measure their environmental impact, optimize resources and drive impactful environmental changes.
These past months I have been working for a pioneer company in adopting sustainable IT practices to measure and reduce its impact on the environment. Since 2021, it has been voted every year the world’s most sustainable coffee company.
Thus, I would like to take this opportunity to talk about how Big Data and analytic tools are used to improve sustainability. This article explores diverse ways in which data analytics empowers companies to become more sustainable.
Energy efficiency and resource management
One of the primary applications of data analytics in sustainability is improving energy efficiency. These tools allow organizations to collect and process multiple data related to resource consumption and carbon footprint to identify which elements of the company are responsible for the most emissions. This way they can implement actions to reduce energy consumption, carbon footprint and develop predictive environmental models.
For example, Google uses data analytics to manage its data centers’ energy consumption. They use machine learning algorithms to analyze vast amounts of operational data from its data centers. These models process data on temperatures, power usage, cooling efficiency and workload distribution, which allow them to apply the most energy-efficient configurations. With this approach Google has reduced energy usage by predicting the optimal cooling configurations, resulting in an important reduction in energy needed for cooling.
Supply chain optimization
Supply chain is a significant area where data analytics can drive sustainability. Through data analysis, companies can track the efficiency of the different steps in their supply chain. They can optimize inventory management by providing real-time insights into demand patterns, inventory levels and lead times. This data also allows them to optimize transportation routes and identify the best paths of transportation, resulting in critical reductions in emissions, fuel consumption and transportation costs.
Walmart employs data analytics to optimize its supply chain reducing greenhouse gas emissions. They use advanced algorithms and GPS devices to gather data related to delivery schedules, traffic patterns and fuel consumption. In addition, their real-time inventory management system allows them to track inventory levels, sales patterns and demand forecast. By analyzing all this data Walmart has been able to improve fuel efficiency, reduce overproduction and excess inventory, and decrease its carbon footprint significantly.
Sustainable product design
The design of environmentally friendly products is one of the areas in which most industries are focusing their efforts. Data analytics plays a key role in evaluating the environmental impact on products throughout their entire life cycle. By evaluating data on materials, energy consumption and waste generation, organizations can take actions related to product design and development. The use of these tools helps businesses to create more sustainable products, use biodegradable materials and reduce excess packaging.
Nike uses data analytics to design sustainable products, such as Flyknit line of shoes. First, advanced analytics helped them to gather and analyze biomedical data from athletes, including foot movements, pressure points and performance metrics. Then they used data analytics tools to analyze material usage and waste patterns in traditional shoe manufacturing, allowing them to detect inefficiencies in material cutting and assembly processes. With all these insights they were able to design and create a lighter shoe with less environmental impact. The result is that Flyknit manufacturing process reduces material waste by about 60% compared to traditional methods.
Sustainability, goal setting and tracking
Setting and tracking sustainability goals is essential for continuous improvement. By gathering, collecting and measuring data from multiple sources, data analytics tools enable real time monitoring of the company’s environmental impact, allowing organizations to make fast and data driven decisions. Thus, this approach ensures accountability and facilitates continuous improvement in sustainability practices.
For example, Johnson & Johnson uses data analytics to track its progress towards sustainability goals. They use sensors and Internet of Things (IoT) devices to gather data on energy consumption and carbon emissions, feeding this data into analytical models that suggest optimization actions. With this approach they can adjust their strategies, adopt new technologies and refine their goals to ensure ongoing progress.
Environmental trends forecast
The environmental impact of the company should not only affect current processes, but should also take into account future predictions. Data analytics can assist with accurate forecasts by analyzing market trends and historical data. Thus, the optimization of ecological processes involves the application of data-based predictive models that can identify potential environmental problems before they occur, allowing organizations to take actions to ensure that certain risks do not occur in the future or at least minimize their impact.
IBM’s Environmental Intelligence Suite uses data analytics to forecast environmental trends, such as extreme weather events, and assess risks to operations and supply chains. On- demand historical weather data provides access to past weather data to inform predictive models. This allows the company to prepare and mitigate the impact of environmental changes, ensuring business continuity and reducing potential environmental harm.
Final conclusions
Data analytics has emerged as a crucial tool for companies to become more sustainable by providing actionable insights into energy usage, waste management, supply chain efficiency and more. By harnessing the power of data, organizations can gain valuable insights into their operations and market trends. And through predictive modeling and data-driven strategies, businesses can optimize resource allocation, reduce waste and contribute to environmental management.
It is true that integrating data analytics presents several challenges that can vary depending on the size and resources of a company. The complexity and the financial investment required to implement these tools are significant and these costs can be a major barrier for
most businesses. In addition, they require an advanced level of expertise to interpret data and translate it into actionable insights. Thus, the integration of data analytics into sustainability should be done as a strategic investment that aligns with business objectives, ensuring that the benefits justify the costs and complexities involved. This not only benefits the environment but also drives cost savings and improves their competitive advantage.

In this previous post, I shared what I called The four cardinal points every senior software engineer must follow to progress in their career. One of these is Prioritization by Business Value, which invite you to take decisions driven by their impact on the business, simplicity and flexible are key to do it.
The More Flexible, the More Value
“A good architecture makes the system easy to change, in all the ways that it must change, by leaving options open.”
— Robert C. Martin, Clean Architecture
A flexible architecture allows you to deliver early and long-term business value more easily. One tip for your career as an Agile Software Architect is to prioritize decisions that enable you to delay defining specific architectural details. This includes delaying choices related to frameworks, protocols, databases, configurations, message brokers, and other external dependencies.
By delaying these decisions, you leave room for better choices when you have more information, avoiding premature commitments to technologies that could limit your solution’s adaptability in the future. Clean architecture, for example, helps you abstract these details and focus on core business logic without being tightly coupled to specific technologies early on.
The Simpler, the More Value
“Everything should be made as simple as possible, but not simpler.”
— Albert Einstein
As Agile Software Architects, our goal is to deliver value in the simplest way possible. Design decisions should focus on reducing unnecessary complexity, especially early in a project. For instance, instead of diving straight into complex architectures like microservices, consider simpler solutions that meet current needs and allow for easy evolution over time.
In my experience, I’ve seen projects that started with microservices from the beginning and failed because this architecture introduced unnecessary complexity. Managing service coordination, network overhead, and data consistency added more challenges than benefits at that stage. A simpler approach, like a monolithic architecture, would have saved time and resources, allowing the team to focus on delivering value earlier.
While microservices are great for scaling when necessary, starting simple and evolving as your system grows keeps your architecture flexible and easier to manage. By avoiding premature decisions, you prevent technical debt and ensure smoother progress.
Let me know your thoughts about this.
-Carlos.G
In our previous article, we emphasized that software architects working within an Agile framework need to be receptive to ongoing changes and continuous feedback. This necessity arises primarily from one central focus – the delivery of continuous value.
Delivering Value with Agile
Adopting an Agile approach means our primary objective is to deliver continuous value, which isn’t always in the form of a completed feature. For instance, suppose there’s uncertainty about the feasibility of a task. In that case, we can formulate and test a hypothesis to gain insights into the issue. This investigative process delivers value to stakeholders. The insights derived from the research inform us whether a task is achievable or not, thereby enabling us to make data-driven decisions and take informed actions.
Initiation and Conclusion of the Design
In order to answer the question of when to initiate and conclude our design phase for maximizing value delivery, let’s revisit the Software Development Life Cycle (SDLC). Typically, it’s segmented into six primary phases: planning, requirement analysis, design, development, testing, deployment, and maintenance. Within the Agile framework, we cycle through these stages repeatedly since we incrementally implement solutions. Consequently, we are continually engaged in the design process as we add new features. The design phase concludes when the solution is either complete (if such a point exists) or ceases to add value.
Divide and conquer
“The secret of getting ahead is getting started. The secret of getting started is breaking your complex overwhelming tasks into small manageable tasks, and then starting on the first one.”
Mark Twain
Drawing from my experience, customer-expressed problems often carry an element of ambiguity, which may be attributed to the scale of the issue. Frequently, the identified problem is expansive. In such instances, it’s beneficial to break it down into smaller, more manageable sub-problems. This approach not only simplifies the resolution process but also ensures accuracy in our efforts. Moreover, it allows us to adopt an incremental problem-solving strategy, enabling us to gain feedback with each resolved sub-problem.
Designing involves not only resolving problems but often identifying them as well. My recommendation is to first accurately pinpoint the problem, which necessitates validating the identified requirements. Once done, select the crucial requirements that the design solution will address. These chosen requirements will guide your architectural decisions effectively. The elicited requirements should be chosen based on the scope of the current iteration, meaning different requirements will be addressed in each iteration. In upcoming posts, we will delve deeper into this process of identifying and selecting the correct architectural drivers for each iteration.
Join the Conversation: Share, Learn, and Grow
As we continue to explore the nuances of software design within an Agile framework, your insights and experiences can enrich the conversation. I invite you to share your thoughts, ideas, or questions in the comments section below. Have you faced similar challenges in your projects? How have you addressed them?
