The Impact of the Internet of Things on Business

The Internet of Things affects business by turning physical equipment, buildings and vehicles into sources of real-time data. That data supports predictive maintenance, energy savings, inventory visibility and safer workplaces. It also expands the attack surface, because every connected device is a potential entry point. The net impact depends on clear use cases, integration and security discipline.

Key takeaways

  • IoT value comes from decisions the data improves, not from the number of connected devices.
  • The biggest gains usually appear in maintenance, energy, asset tracking and safety.
  • Device security, patching and network segmentation must be planned before deployment.
  • Integration with existing systems (maintenance, ERP, workforce tools) decides whether insights lead to action.

What is the Internet of Things?

The Internet of Things (IoT) describes physical objects fitted with sensors, processing and software that exchange data with other devices and systems over the internet or other networks. In business, that includes machine sensors on production lines, smart thermostats and lighting in buildings, GPS units on vehicles, RFID tags on inventory, and wearable devices for worker safety.

Most enterprise IoT setups share four layers: devices that sense or act, connectivity (Wi-Fi, cellular, low-power networks), a platform that collects and processes data, and applications or dashboards where people make decisions.

Where does IoT have the most business impact?

AreaIoT useDecision it improves
ManufacturingVibration, temperature and runtime sensors on equipmentWhen to service a machine before it fails
FacilitiesOccupancy, lighting, HVAC and air quality sensorsHow to schedule cleaning, energy use and space
LogisticsGPS, telematics and cold chain temperature monitorsHow to route vehicles and protect sensitive goods
Retail and warehousingRFID and shelf sensorsWhen to replenish and where stock is located
HealthcareConnected medical devices and asset tagsWhere equipment is and whether it is available
Workforce safetyWearables and environmental sensorsWhen to alert workers about heat, gas or restricted zones

Smart buildings are one of the most visible uses, but they bring their own operational challenges. Our article on the challenges of smart facility management covers integration, cost and skills issues in more detail.

How does IoT change the way people work?

IoT shifts many roles from scheduled routines to data-triggered work. Maintenance technicians respond to sensor alerts instead of walking fixed inspection rounds. Facility teams clean rooms based on actual use. Dispatchers adjust routes in real time.

That change has HR and management implications:

  • New skills: technicians need to read dashboards and trust data, and IT teams need operational technology knowledge.
  • Clear policies: wearables or location tracking can feel like surveillance. Explain what is collected, why and who sees it.
  • Workflow integration: an alert that does not create a work order or reach the right person on shift is easy to ignore.

What are the security risks of IoT?

Many IoT devices ship with weak default credentials, limited update mechanisms and long lifespans. Once installed, they can stay on a network for years without patches. The NIST Cybersecurity for IoT Program publishes guidance, including the NISTIR 8259 series, describing baseline security capabilities manufacturers should build into devices and what organizations should expect.

IoT security checklist

  • Keep an inventory of every connected device, its owner and its firmware version.
  • Change default credentials and disable unused services.
  • Segment IoT devices onto separate networks away from business systems.
  • Confirm the vendor provides security updates and a support period in writing.
  • Monitor device traffic for unusual behavior.
  • Plan secure decommissioning, including data wiping.

Much IoT data ends up in cloud platforms, so cloud controls matter too. See our guide to cloud security techniques for HR and IT leaders.

How should a business plan an IoT project?

  1. Start with a decision. Name the decision you want to improve, such as reducing unplanned downtime on a specific line.
  2. Define the data needed. Identify what to measure, how often and with what accuracy.
  3. Check connectivity. Factories, warehouses and remote sites may need new network coverage. Advances in cellular networks matter here; our piece on digital transformation and 5G availability discusses the connectivity side.
  4. Plan integration. Decide which system receives alerts and who acts on them.
  5. Pilot small. Test on a limited set of assets, measure the result against a baseline and refine.
  6. Scale with governance. Standardize device approval, security reviews and data ownership.

Frequently Asked Questions

What is the difference between IoT and industrial IoT?

Industrial IoT (IIoT) refers to connected sensors and machines in industrial settings such as manufacturing, energy and utilities. It usually involves stricter requirements for reliability, safety and integration with operational technology like control systems. General IoT also includes consumer and commercial devices such as smart thermostats, wearables and building sensors.

Is IoT only for large enterprises?

No. Smaller organizations use IoT for vehicle tracking, energy management, refrigeration monitoring and security systems, often through subscription services. The same principles apply: start with a clear problem, confirm the vendor supports security updates, and make sure someone is responsible for acting on alerts.

How long does it take to see value from IoT?

It depends on the use case. Simple monitoring, such as temperature alerts for refrigeration, can show value quickly. Predictive maintenance often takes longer because models need historical data to learn normal patterns. Setting a baseline before deployment is the only reliable way to measure the impact in your own operation.

Next steps

Choose one operational problem where better real-time data would change a decision, inventory any connected devices you already have, and run a security review of them. Then pilot a focused IoT project with a clear owner, baseline and integration plan.

Why Workday Onboarding Breaks Down for Frontline Employees

Image
The Onboarding Gap Nobody Talks About Workday's onboarding module is well-designed for its intended audience: office-based, desk workers with reliable computer access, personal email addresses, and the digital literacy to navigate a web-based portal. For this population, Workday onboarding works well, it automates tasks, routes approvals, collects documents, and creates a reasonably smooth first-week experience. But most organizations using Workday have a substantial population of frontline workers: warehouse employees, retail staff, manufacturing workers, healthcare aides, food service workers, drivers. For this population, the standard Workday onboarding experience frequently fails in ways that are predictable, documented, and, crucially, fixable. Understanding why it breaks down and what actually works is increasingly urgent as labor market competition for frontline talent intensifies.

How to Improve the Customer Experience (CX)

Customer experience is the sum of every interaction a customer has with your company, from the first ad they see to the way a return gets handled years after the purchase. Companies that take this seriously outperform those that treat CX as a support function. The ones that struggle tend to confuse customer satisfaction scores with actual improvements, or fix the wrong things. Here's a practical look at what actually moves CX forward. Start with where customers actually struggle Most CX improvement programs begin with surveys. Surveys are useful but limited, they capture what customers are willing to articulate after the fact, which tends to under-report friction in the middle of an experience and over-index on the most recent interaction. The richer data comes from observing behavior directly: where do customers drop off in a purchase flow? Where do support tickets spike? What search queries are people entering on your site that suggest they can't find what they're loo...

How Do I Log In and Sign In to Workday HCM

Workday HCM is the system your organization uses to manage everything from your pay stubs and benefits to time off requests and performance reviews. Getting in is usually simple once you know where to go, but first-time login, password resets, and single sign-on setups can trip people up if no one has walked them through it. Here's what you need to know. How to find your Workday login URL Workday doesn't have one universal login page. Each organization has its own tenant, a dedicated instance with a unique URL. Your company's HR department or IT team should have provided the URL when you were onboarded. It usually looks something like your-company.workday.com or wd3.myworkday.com/yourcompany . If you weren't given the URL, check your onboarding email, your company's intranet, or ask HR directly. Some organizations also link to Workday from their internal HR portal. Don't try to guess the URL, there's no central directory, and guessing wrong just takes...

UKG Union Contract and Overtime Rules for Multi-Site Food Plants

Multi-site food manufacturers running UKG often struggle with one thing: each plant has its own union contract, shift pattern and overtime rules, while the timekeeping system is configured centrally. The fix: document every contract rule precisely, map it to UKG pay rules and work rules, test against real timecards, and handle true exceptions with add-ons rather than core customization. Disclosure: The author works at CloudApper, which makes the UKG add-ons discussed in this article. Why are union contracts so hard to configure in UKG? Federal law sets a floor. Under the Fair Labor Standards Act, non-exempt employees must receive at least one and a half times their regular rate for hours worked over 40 in a workweek. Collective bargaining agreements frequently go further, and food plants often have several agreements across locations. Common contract provisions include: Daily overtime after 8 hours, or after 10 on a four-day schedule. Double time on the seventh consecutive day o...

Infor HCM Software Engineer Jobs: Salary Factors and Skills

An Infor HCM software engineer's salary depends mostly on the type of employer, the depth of Infor platform knowledge, and location. Engineers who combine general software skills with hands-on experience in Infor CloudSuite HCM, Lawson, Infor ION integrations and payroll logic tend to command more than generalist developers, because that combination is scarce in the job market. What does an Infor HCM software engineer actually do? The title covers several different jobs, and pay follows the job more than the title. Broadly, these engineers build, configure, integrate and support the Infor human capital management stack, which includes core HR, payroll, benefits, talent management and workforce management. Many organizations still run the older on-premises Infor Lawson system alongside or instead of the cloud suite, so experience with both is common. Typical responsibilities include: Building and maintaining integrations between Infor HCM and payroll providers, benefits carrie...

ERP Solution Guide: How to Choose the Best ERP for You

What Is an ERP System and Why Does It Matter? An enterprise resource planning (ERP) system is software that integrates the core functions of a business — finance, inventory, procurement, human resources, manufacturing, and customer management — into a single, connected platform. Instead of data living in separate spreadsheets or standalone applications that don't talk to each other, an ERP creates one source of truth for the entire organization. For growing companies, the question is usually not whether they need an ERP but when and which one. Getting this decision right has long-term consequences. A poorly chosen ERP creates more problems than it solves — forcing teams to work around the system, creating data integrity issues, and consuming IT resources in an endless cycle of customization and maintenance. A well-chosen ERP, on the other hand, becomes the operational backbone that lets a company scale without proportionally growing its administrative overhead. Understandin...

The End of Remote Work: Why Companies Want You Back

Return to Office: The Trend Reshaping the Modern Workplace After years of celebrating the remote work revolution, a powerful counter-movement has taken hold. Amazon, JPMorgan Chase, Goldman Sachs, Disney, and hundreds of other organizations have issued return-to-office (RTO) mandates, some requiring full five-day-a-week presence. The era of near-universal remote work flexibility appears to be giving way to something more complicated, and HR leaders are at the center of navigating it. Why Companies Are Calling Employees Back Collaboration and Innovation: Many executives argue that the serendipitous interactions, the hallway conversation, the spontaneous whiteboard session, that drive breakthrough ideas simply cannot be replicated on Zoom. Studies from Stanford and MIT suggest that in-person collaboration produces measurably higher rates of novel idea generation. Culture and Cohesion: Building and sustaining organizational culture at a distance has proven harder than anticipated. N...

How to Search in Workday: Find Reqs, Reports, People and Tasks

To search in Workday, type into the global search bar at the top of any page, press Enter, then use the category filters on the left of the results to narrow to people, organizations, tasks and reports or other object types. Workday only returns items your security roles allow you to see, so missing results often mean an access issue rather than a typo. How does Workday search work? Workday uses a single global search box rather than separate menus for each module. Everything in the tenant, from a worker's profile to a job requisition to a custom report, is an object that search can find if you have permission to view it. Three points explain most search behavior: Security trimming. Results are filtered by your security groups. A recruiter and a payroll partner typing the same term will see different results. Categories. After you press Enter, results are grouped into categories that appear as filters. Clicking one hides everything else. Related actions. Once you open an...

New Apple Watch Health Features Will Be Available This Year, but Blood Pressure and Blood Sugar Sensors Will Not Be Available Until Next Year

Image
What Apple confirmed for its upcoming watch lineup Apple's annual health feature announcements for its Watch lineup continue to generate significant attention, both from health enthusiasts who track every new sensor addition and from the clinical research community that increasingly uses consumer wearables in studies. The pattern that has emerged over the past several product cycles is consistent: Apple confirms a set of features that will ship with the current year's model and acknowledges separately that other, more complex sensors are still in development and will not arrive on schedule. This year's announcement followed that pattern closely. Several new health monitoring capabilities are confirmed for the current Apple Watch generation, representing meaningful additions to what the device can track passively. At the same time, the two most anticipated sensor additions, continuous blood pressure monitoring and non-invasive blood glucose measurement, will not be availa...

Dollar General Store Walkout: Lessons for Retail HR

In March 2024, every employee at a Dollar General store in Mineral Point, Wisconsin, quit at once and posted "We quit" signs on the doors. They cited a lack of appreciation, being overworked and underpaid, and a dispute over a corporate rule limiting which unsold items could be donated. The store reopened about three hours later. Key takeaways The walkout was triggered by a policy change, but the notes employees left pointed to long-running frustration with workload, pay and recognition. Policies that clash with frontline values (such as throwing away usable goods) can become flashpoints when trust is already low. Explaining the reason behind a rule, and giving local teams a channel to push back, costs little compared with a full-store walkout. Retail and hourly employers should treat a mass resignation as a lagging indicator and track earlier warning signs. What happened at the Mineral Point store? According to reporting syndicated by Sinclair stations, customers ...
