      Happiness Planet
      Support System for Promoting Management Objectives in Partnership
      with Employees

      While it is the role of management to formulate and pursue objectives for the future of
      the company, simply announcing these is not enough on its own to gain buy-in from
      employees. This is a consequence of the inevitable gap between these objectives and
      employees’ existing work, making it difficult for them to act on their own initiative.
      Hitachi developed Happiness Planet as a solution for achieving three prerequisites that
      it has identified as necessary for achieving management objectives: the breaking down
      of objectives, proactive participation by employees, and risk monitoring. The solution is
      made up of a smartphone app for employees and a web application for management.
      The benefits of the solution have been demonstrated in a public PoC trial involving
      4,300 participants across 83 companies and Hitachi now plans to roll out the solution
      for commercial use.

      A feature of this approach is that it works from both the top down and the bottom up. The key is for individual employees to select for themselves which
      action they want to perform, taking into consideration their work for the day and the organizational goals. This ensures that management objectives
      permeate all corners of the organization and are carried out in a way that suits the particular circumstances of each workplace.

Figure 4 — Psychological Weather Chart (Management Tool)
      The chart provides a weather report on how employees are getting on. On the basis of social happiness index statistics from a group of people who are
      closely involved with one another at work, the chart shows fine weather when relationships with others are positive and rain when negative. This provides
      early warning of when subordinates are in need of support.
