HRISとは何か。メリットと適切な製品の選び方
FEB 12, 2026
An HRIS is the operational backbone of a modern HR function. This guide explains what it does, why it matters, and how to select the right platform for your organisation.
HRISの定義
A Human Resources Information System (HRIS) is a software platform that stores, manages, and automates the core data and processes of an HR function. At minimum, it maintains an employee database with employment records, personal details, and organisational structure. Most modern HRIS platforms extend to self-service for employees and managers, absence and leave management, document storage, onboarding workflows, and reporting. Some include payroll, performance management, and recruitment as native modules or integrate with best-of-breed specialist tools.
Why every organisation above 50 employees needs one
Below 50 employees, a well-maintained spreadsheet and a shared drive can manage the basics, though even at this size the limitations are starting to show. Above 50, the volume of employee changes, leave requests, documents, and compliance tasks becomes unmanageable without a dedicated system. Above 100, self-service capability becomes essential: managers need to approve leave without emailing HR, and employees need to access their own records without submitting requests. Above 250, the reporting, analytics, and audit trail requirements of growing organisations demand a platform rather than a collection of spreadsheets.
確認すべき主要機能
When evaluating HRIS platforms, prioritise: a reliable employee database with a clean user interface, configurable leave management that handles all the leave types your organisation offers, document management with electronic signature, self-service for employees and managers, a reporting engine that allows you to build custom reports without IT support, and an open API for integration with payroll and other systems. Avoid platforms that require professional services fees for every report or integration change.
選定プロセスの進め方
まず、最も時間のかかるHR管理業務10項目と、最も重要なデータ・報告ニーズ5項目を書き出してください。これらを基に要件書を作成します。それを3～5社のベンダーに提示してください。ベンダーの標準デモ台本ではなく、御社独自のデータシナリオを使ったデモを必ず求めてください。同規模・同業種の組織に対してリファレンスチェックを行ってください。導入、トレーニング、年額費用を含む総所有コストを、従業員1人あたり月額価格だけでなく3年間で評価してください。
