When you work with local personnel using only the phone and email, gaps in understanding arise because of differences in values and sensitivity.
This results in work not progressing as expected.

For example...
During the telework period, we called local personnel and asked them to do an inventory check by the end of the month.
But the local personnel did not consider it to be an official instruction, did not do it, and an accountability issue resulted.

Even if you have a conversation on the phone, it may not register and may be forgotten.
Emailed instructions can also be ignored by excuses such as the personnel in question did not see the email or it was filtered into the spam folder.
So, be sure to prepare an environment that enables you to visualize progress as if you were working together in the office, whereby you can check the progress in detail and share online meeting documents.
 

In telework, more employees participate in BYOD (Bring Your Own Device),
and more confidential internal information being handled outside the office means higher security risks.
Local personnel tend to have less awareness or lack a common awareness of security.

For example...
A local staff member browsed a website privately on a private PC, which got infected with a virus.
Important information leaked, tainting our company's reputation.

Security risks are an issue faced by all staff members.
To avoid accidents such as information leaks, it is important to set and ensure awareness of security guidelines about taking and using documents outside the company.
You also need to set clear company policies on centrally managing devices and VPN access, and apply these policies to all employees.
 

When employees are prohibited from coming to work because of an official notice that bans commuting, operations that can only be processed at the office, such as procurement and ordering, get suspended.

For example...
Our inventory management and ordering system was accessible only from an internal network.
Because of this, we could not place our regular orders during the lockdown, which inconvenienced our customers.

Operations that occur regularly can be automated, though this depends on their content. You can use robots to automate such processes.
You can also prepare a connection to connect remotely from outside the office to connect to your office PC from home,
enabling you to do your regular work without coming into the office.
