Types of Data Management
Database Management: Uses RDBMS (Relational Database Management Systems) for structured data or NoSQL for flexible semi-structured data.
Master Data Management (MDM): Harmonizes critical business data (customer/product) to create a single authoritative source.
Document Management: Organizing and tracking electronic documents via a DMS.
Metadata Management: Managing the "data about data" to help users understand context.
Data Quality Management: Uses profiling, cleansing, and validation to ensure accuracy and completeness.
Data Governance: Establishes the policies, procedures, and roles (e.g., Data Stewards) to manage data assets.
Data Security Management: Focuses on confidentiality, integrity, and availability (CIA).
Data Integration: Combines data from different sources via ETL (Extract, Transform, Load) processes.
Data Warehousing: Centralizes large volumes of data to support BI and reporting.
Big Data Management: Deals with massive volumes in distributed computing environments.
Data Lifecycle Management: Manages data from creation through storage and archiving to disposal.
Data Management Strategy Development Steps
Define Business Objectives: Understand goals and the specific data required to support them.
Assess Current State: Evaluate existing infrastructure and capabilities.
Establish Governance Framework: Define policies, roles, and responsibilities.
Create Data Inventory: Categorize all assets based on usage and sensitivity.
Ensure Data Quality: Implement tools for profiling, cleansing, and validation.
Enhance Security: Implement encryption, access controls, and audits.
Implement Integration Architecture: Design for scalability and interoperability.
Foster Data-Driven Culture: Promote data literacy and collaboration between IT and business teams.
Invest in Scalable Technology: Select tools that align with business goals.
Establish Lifecycle Management: Define plans for archiving and disposal.
Monitor Performance: Set KPIs to measure strategy effectiveness.
Continuous Improvement: Update strategies based on new regulations or technologies.
Sources and Collection Processes for HR Data
Human Resources Information System (HRIS) Sources: - Recruiting Data: Captured via ATS (Applicant Tracking Systems); includes funnel metrics and sources. - Demographic Data: Found in employee records (ID, gender, position, department). - Performance Management Data: Reviews and ratings within a PMS. - Learning Management Data: Training progress and course offerings in an LMS. - Job Architecture: Definitions of salary scales, bands, and grades. - Compensation & Benefits: Details on salary, bonuses, and secondary benefits. - Succession Planning: Leadership development data and bench strength metrics. - Exit Interview Data: Reasons for turnover to analyze retention.
Secondary/Other Sources: - Business Data: CRM data (customer satisfaction/NPS), Sales data (per store/department), Financial data (ROI for training, cost per person). - Other HR Data: Mentoring challenges/outcomes, engagement surveys, wellness initiatives (work-life balance).
Validity Principles in HR Data Collection: - Content Validity: Ensuring instruments cover all relevant aspects of the skill being assessed. - Criterion Validity: Checking if data correlates with performance outcomes (e.g., correlating evaluation scores with actual sales figures). - Construct Validity: Measuring underlying theoretical attributes correctly. - Expert Review: Feedback from HR subject matter experts. - Pilot Testing: Identifying issues before full-scale implementation.
Gartner's ABCD Framework for HR Data Quality: - Accuracy: Is every detail correct? Can the data be trusted? - Breadth: Is the data complete or are there missing gaps? - Consistency: Is the standard applied uniformly across formats and methodologies? - Depth: Is the data granular enough to target specific business units or individuals?
Data Preparation and Cleaning
Statistics on Prep Time: Data scientists spend 45\% 60\% extreme values0.951.05\text{Total Revenue} / \text{Number of Employees}(\text{Number of absent days} / \text{Total working days}) \times 100110$$.
ROI for Training: The financial gain an organization realizes from a specific training program.
Ethical Information Management
Business Ethics: Moral principles, policies, and values governing business conduct beyond legal requirements.
Legislative Frameworks (South Africa): - POPIA (Protection of Personal Information Act): Regulates lawful processing of personal data and privacy rights. - ECTA (Electronic Communications and Transactions Act): Legal framework for electronic transactions and data integrity. - LRA (Labour Relations Act): Guidelines for handling employee info within employment contracts and disciplinary records.
Professional Code of Conduct (5 Pillars): 1. Integrity. 2. Objectivity. 3. Competence. 4. Confidentiality. 5. Professionalism.
10 Principles for Successful Info Management Projects: 1. Recognize and manage complexity. 2. Focus on adoption (change management). 3. Deliver tangible and visible benefits. 4. Prioritize based on business needs. 5. "Journey of a thousand steps" (many small updates rather than one massive project). 6. Provide strong leadership. 7. Mitigate risks (early pilots). 8. Communicate extensively. 9. Strive for a seamless DEX (Digital Employee Experience). 10. Choose the first project very carefully (must be a catalyst).
Effective Business Communication and Reporting
Communication Directions: - Upward: Subordinate to manager (feedback, suggestions). - Downward: Supervisor to subordinate (policy, goals, delegation). - Lateral: Between peers of equal rank (collaboration, coordination). - External: Between organization and outside parties (clients, vendors).
Report Elements: - ToR (Terms of Reference): Defines what the report is about, why it is necessary, and its purpose. - Findings: Presentation of data interpretation. - Recommendations: Suggested courses of action based on evidence.
Effective Writing Steps: 1. Decide on Terms of Reference. 2. Conduct Research. 3. Create an Outline (Title page, Intro, Findings, etc.). 4. Write First Draft (don't worry about perfection). 5. Analyze Data and Record Findings. 6. Recommend Course of Action. 7. Edit and Distribute.
