To Avoid Failing in Back Office Operations and System Implementation — 4 Common Pitfalls and Tips for Solutions

  • NEW
  • OTHER

Caught up in daily input, approval, and checks, I want to improve but can't find the time to consider it. In back offices, which tend to fall into such a "negative loop," it's understood that system implementation can be a breakthrough, but the burden of the implementation itself is often significant, leading to new sources of concern. During the consideration phase, it takes time to request materials and compare demos, and even if the differences are clear, there is no certainty about whether it will fit the company. After implementation, issues often arise in operations, such as not being able to connect to support or having multiple inquiry points that cause confusion. Therefore, while organizing common failure cases, we have summarized key points for practical staff to proceed with a selection that is "smooth," "thorough," and "without regret." Common failure case 1: The purpose is vague, and "systematization" becomes the goal. Common failure case 2: It does not match the company's operations. Common failure case 3: Realizing it is "difficult" after starting to use it. Common failure case 4: Total costs balloon. You can read more without needing to input personal information.

[Please introduce this to the management and general affairs department] Update on the introduction case of the attendance management system! We've moved away from manual input of attendance data! With biometric authentication for attendance management, we can now ensure transparency and accuracy.

  • NEW
  • OTHER

An article has been published regarding the case study of the attendance management system "KING OF TIME" implemented at Nichirei Industrial Co., Ltd. ~ In the case of Nichirei Industrial ~ The workload related to attendance management has decreased. With the transition from analog tasks to automated aggregation of working hours and granting of annual leave, we can now focus on our work with peace of mind. Particularly regarding the "punching method," we utilize fingerprint and facial recognition. By using biometric authentication, impersonation is not possible, and I believe the accuracy of attendance has significantly improved. Transparency has been ensured. 【Case Overview】 ■Challenges Before Implementation - Handwritten attendance sheets were used, resulting in input tasks to incorporate data into the payroll system. ■Key Points of Implementation - Systematization has reduced input tasks. Biometric authentication prevents impersonation. *For more details, please refer to the related links or feel free to contact us.
