1. Executive Summary & Purpose

This Standard Operating Procedure (SOP) defines the institutional engineering standard for designing, reviewing, versioning, and deploying standardized timesheet templates across Template Registry. The purpose of this document is to eliminate billing variance, ensure regulatory compliance with international labor standards, and provide an immutable audit trail for resource allocation and capital expenditure (CapEx) tracking. Compliance with this SOP is mandatory for all engineering, finance, and human resources units.

2. Scope & Prerequisites

2.1 Scope

This protocol applies to all internal and external personnel submitting time, billable hours, or project allocations via the Template Registry ecosystem. It governs templates deployed across Microsoft Excel, Google Sheets, Jira Work Management, and the native Enterprise Time and Attendance Portal (ETAP).

2.2 Prerequisites & Tooling

• Software Requirements:
  • Microsoft Office 365 (Excel Version 2308+) with Data Validation and VBA macros disabled unless cryptographically signed.
  • Google Workspace Enterprise (Sheets with Apps Script restricted to whitelist).
  • Template Registry Core CLI (tr-cli v2.14.0+).
• Access Control:
  • Active Directory (AD) security group membership: sec-grp-payroll-architects.
  • GitHub Enterprise write access to template-registry/financial-artifacts.
• Hardware / Physical Equipment: Standard enterprise workstation (no specialized PPE required; purely administrative systems engineering workflow).

3. Roles & Responsibilities (RACI Matrix)

• Responsible: Executes the step-by-step procedures.
• Accountable: Owns the accuracy, validity, and audit readiness of the artifact.
• Consulted: Provides domain input on tax, labor laws, and accounting integrations.
• Informed: Receives deployment notifications and change logs.

4. Step-by-Step Procedure

Phase 1: Schema Design & Version Control

• 1.1 Clone the master repository branch containing the schema definition:

  git clone https://github.com/template-registry/financial-artifacts.git
  cd financial-artifacts/timesheet-core
  

• 1.2 Validate that the JSON schema (schema.timesheet.v4.json) includes mandatory metadata fields: Employee_ID, Cost_Center_Code, Project_WBS, Regular_Hours, Overtime_Hours, and PTO_Hours.
• 1.3 Increment the version number in the metadata header using Semantic Versioning (SemVer).

Phase 2: Template Assembly & Formatting

• 2.1 Open the base template file in the designated authoring software (Excel/Sheets).
• 2.2 Enforce cell locking and formula protection on all calculation engines (e.g., Gross Pay, Overtime Multipliers) to prevent local user tampering.
• 2.3 Implement strict Data Validation rules on input ranges:
  • Hours per day: 0 <= x <= 24
  • WBS Codes: Regex match ^[A-Z]{3}-\d{4}-\d{2}$
• 2.4 Apply the mandatory Template Registry visual hierarchy (Monospace font for numerical data, system color palette #1F2937 for primary headers).

Phase 3: Integration & Validation Testing

• 3.1 Execute the automated validation test suite via the CLI:

  tr-cli validate --template ./dist/Timesheet_Template_v4.2.xlsx --schema ./schema.timesheet.v4.json
  

• 3.2 Perform a dry-run data ingestion into the staging ERP environment to verify API payload mapping.
• 3.3 Confirm that error-handling cells output standardized error codes (#ERR_WBS_INVALID, #ERR_HOURS_EXCEEDED) rather than raw stack traces.

Phase 4: Deployment & Distribution

• 4.1 Export the finalized template artifact to the secure S3 storage bucket:

  aws s3 cp ./dist/Timesheet_Template_v4.2.xlsx s3://tr-enterprise-templates/finance/current/
  

• 4.2 Update the registry-manifest.json file to point all automated ingestion pipelines to the new version hash.
• 4.3 Issue a system notification via the internal broadcast tool directing users to download the updated documentation package.

5. Quality Assurance & Pro-Tips

5.1 Best Practices

• Immutability: Never overwrite an existing production timesheet template. Always increment the minor or major version to preserve historical audit data.
• Formula Isolation: Keep UI presentation layers strictly separated from calculation engines. Hardcoding values into formula cells is a critical audit violation.

5.2 Common Pitfalls

• Timezone Drift: Ensure all date-time stamps inside the template metadata default to UTC to prevent discrepancies for distributed teams.
• Macro Bloat: Avoid embedding unverified VBA or Apps Script macros; use native formula logic wherever possible to minimize security attack vectors.

5.3 Metric Thresholds

• Ingestion Error Rate: Must remain $< 0.05%$ across all automated batch processing runs.
• Template Render Latency: Local file recalculation must complete in $< 250\text{ms}$ on standard hardware configurations.

6. Frequently Asked Questions (FAQ)

Q1: What happens if an employee submits a timesheet using a deprecated template version?
A: The automated ingestion pipeline will reject the payload with an error code #ERR_DEPRECATED_SCHEMA. The system will automatically route a notification to the user containing a link to download the current production-grade template (v4.2.0).

Q2: How are retroactive corrections handled for locked timesheets?
A: Locked timesheets cannot be edited locally. The employee's direct supervisor and the Cost Center Manager must submit a signed SOP-TR-FIN-012 Variance Adjustment Form directly to payroll, which executes an audited manual database override.

Q3: Can custom project codes be added locally by department leads?
A: No. All Work Breakdown Structure (WBS) codes are dynamically pulled via API from the central Enterprise Resource Planning (ERP) database. Local manual entry of project codes is blocked by cell-level input validation.
