Definition
Operational Ease describes the degree to which the application
attends to operational aspects, such as start-up, back-up, and
recovery processes.
Operational ease is a characteristic of the application. The
application minimizes the need for manual activities, such as tape
mounts, paper handling, and direct on-location manual intervention.

No special operational considerations other than the
normal back-up procedures were stated by the user. |
1 - 4 |
One, some, or all of the following items apply to the
application. Select all that apply. Each item has a point value
of one, except as noted otherwise.
- Start-up, back-up, and recovery processes were provided,
but human intervention is required.
- Start-up, back-up, and recovery processes were provided,
but no human intervention is required (count as two items)
- The application minimizes the need for tape mounts and/or
remote data access requiring human intervention
- The application minimizes the need for paper handling.
|
5 |
The application is designed for unattended operation.
Unattended operation means no human intervention is required to
operate the system other than to start up or shut down the
application. Automatic error recovery is a feature of the
application. |
Hints
- Application has the ability to perform start-up, back-up, and
recovery; however, human response is required to initiate the
function.
- Application has the ability to perform start-up, back-up, and
recovery; and no human response is required to initiate the
function.
- If the application has conversion and installation
requirements and installation guides were provided, and providing
these functions and guides were on the critical path of the
project, score a 3.
- The application minimizes the need to access data that is not
immediately available.
- This may include importing data from a distributed processor
to the local processor prior to execution to eliminate access
delays.
- The application has been designed to provide the user with
data in a condensed format or via a media other than paper.
- This could include elimination of detailed printed information
or access to on-line reports, inquiries, microfiche, CD, or other
such media.
- A score of 5 is assigned to an application that runs and
recovers automatically from errors, on its own – an unattended
operation.
- Unattended operation may include unmanned satellite, nuclear
reactor, or air traffic control.
Typically
Scoring is not platform dependent.
