What is “big data” in the HR context?
Big data is the huge volume of diverse, fast-moving data (from systems, devices, social media, etc.) that organizations can capture and analyze to see patterns, predict outcomes, and support evidence-based HR and business decisions.
What are the three “V” features of big data, and why do they matter for HR?
Volume – massive amounts of data.
Velocity – data generated and updated very quickly.
Variety – many formats (numbers, text, images, audio, sensor data).
They drive the need for scalable systems and analytics so HR can turn raw data into useful insights.
What are the three ways big data can help HR, according to SHRM?
Collecting new data – about how, when, and where employees work to improve processes and reduce errors.
Using existing data more effectively – understanding engagement, motivation, and why employees behave as they do.
Better strategic analysis – mapping information flows and work relationships to support more strategic decisions.
What must HR do to really capitalize on big data?
Partner with IT to gather the right data at the right intervals.
Use systems that can take in diverse data formats and refresh them.
Ensure systems are scalable and include strong analytics tools so value comes from analysis, not just database size.
Give two practical HR examples of how big data can be used.
Analyze employee profiles to link performance/tenure with variables (education, location, assessments) to improve selection and retention.
Detect issues, such as turnover spikes in one location, and forecast workforce surpluses/shortages by role or competency.
What is an information system (IS) in simple terms?
An IS is a way to collect, organize, store, analyze, and share data so the organization can support operations, decision-making, and communication.
What are the four basic tiers (layers) of an information system?
Presentation tier – what the user sees and interacts with (screens, UI).
Logic tier – the rules and business logic that drive operations.
Data tier – where data is stored and managed.
Communications tier – how data moves across internal and external networks.
In the context of IS, what does integration mean and why is it important?
Integration is the extent to which users share the same data across systems. High integration reduces duplication, errors, and manual work, and supports consistent, real-time information across functions
What is an ERP system, and what problem does it solve?
Enterprise Resource Planning (ERP): an integrated suite that lets different parts of the organization (finance, HR, operations, etc.) access a common data set.
It reduces silos, supports cross-functional coordination, and improves process efficiency
What is an HRIS, and how does it relate to ERP?
HRIS (HR information system): technology that supports HR functions and enables HR to gather, store, maintain, retrieve, analyze, and report HR data.
It can be a module within an ERP or a stand-alone solution that connects to the enterprise data environment
What are “best of breed” (BoB) HR systems, and what is the key trade-off?
BoB systems are specialized HR tech products designed to solve a specific HR need very well (e.g., recruiting, learning).
Trade-off: strong functional depth but potential integration and data-sharing challenges with the main ERP and other systems; may require interfaces or manual work.
In technology management, what is scalability, and why does HR care?
Scalability is a system’s ability to handle more data, users, and transactions without performance degradation. HR cares because data, automation, and self-service keep expanding, and systems must grow without slowing down or becoming too expensive
What are the main benefit dimensions of cloud computing mentioned in the SHRM slides?
Flexibility – easy to scale up or down.
Economy – pay-for-use; less investment in hardware.
Control – can vary depending on on-prem vs private vs public cloud.
Security – must be carefully evaluated in vendor selection
Why is cloud computing attractive for HR technology?
Provides on-demand capacity without buying servers.
Simplifies access for mobile and global users.
Shifts hardware and maintenance responsibilities to the vendor.
Often lowers upfront costs compared to on-prem solutions.
What three key security steps does SHRM highlight for HR tech?
Ensure confidence in security of purchased systems and software.
Assign appropriate user security levels (role-based access).
Implement governance policies and processes to ensure transparency and accountability
What are four general things HR software products can do?
Automate complex processes (e.g., recruiting, onboarding).
Produce data that can feed other applications (e.g., skill profiles into workforce planning).
Support data analysis and dashboards.
Support compliance-related activities (reports, audits, legal tracking).
What is Software as a Service (SaaS) in the HR tech context?
SaaS is software that is owned, delivered, and managed remotely by a provider, accessed over the Internet, usually via subscription or pay-for-use, with updates handled by the vendor rather than installed locally
What are key advantages of SaaS for HR?
No need to install/maintain software on internal servers.
Scalable capacity and ability to add features.
Frequent updates and enhancements included.
Often faster implementation and lower upfront costs
What is artificial intelligence (AI) as used in HR technologies?
AI is the ability of a computer system to imitate human thought and behavior, such as understanding patterns, making predictions, and interacting with users through self-learning, speech/optical recognition, and virtual “assistants.
Give two examples of how AI can enhance HR technologies.
Self-learning chatbots that improve help-desk or candidate support based on user interactions.
Virtual representatives (avatars/voice bots) that guide employees through HR processes (benefits enrollment, policy questions)
How is machine learning (ML) related to AI in HR tech?
ML is a subset of AI focused on systems that can learn from data and gradually improve accuracy of predictions or classifications (e.g., predicting attrition, matching candidates to jobs)
What are employee self-service (ESS) technologies?
ESS tools let employees view and update their own HR data and complete HR-related transactions (time off, benefits enrollment, personal information, performance docs) via portals, often 24/7
What are manager self-service (MSS) technologies, and why do they matter?
MSS tools give managers direct access to employee data and HR transactions (approve leave, pay changes, promotions, performance reviews, succession information), reducing e-mail back-and-forth, increasing efficiency, and freeing HR for more strategic work
What are the four big steps in purchasing HR technology shown on the SHRM slide?
Assess needs and prioritize requirements.
Identify and assess providers.
Create a business case.
Implement and assess the selected technology.
