The context

The following technology drivers:

Hand-held wireless computing,

Global connectivity (real-timeinternet access) and

Collaborative analytics

are changing the way in which plant

maintenance is carried out


3/20

Study objective

To analyse how tablet and smartphone technologies can

be applied to increase the efficiency and effectiveness of

maintenance planning and scheduling.


4/20

Methodology

The major capabilities of hand-held devices are mapped

against the steps required to plan and schedule

maintenance jobs.

These capabilities evaluated and ranked according to

five main value drivers:

cost,

speed,

quality,

safety and

environment.

Labor productivity

Time-on-tools varied between a low of 20% and a high of55%, with average value of 36% across all industry sectors.

Principal reported losses include:

time spent on non-routine work;

partially reported work hours,

gaps between recorded hours and best practice;

poor inventory management;

rework;

misapplication of machinery;

losses in parts, tools, instructions and

travel, procedural delays; punctuality and tool preparedness.

E-Maintenance Value drivers

Five value drivers were identified for improving the

maintenance planning and execution processes;

Speed

Quality

Cost

Safety, and

Environment

Opportunities Planning

Embedding photos and/or video frames of actual

equipment and site conditions can convey information to

the planner beyond the capability of words

Time and resource requirements for each task can be

determined with reference to historical work order

records

Tracking of job completion times using the GPS and

clock functions


13/20

Opportunities - Scheduling

Resource status (spares, tools, labour) can be checked

using hand held devices.

Barcode readers installed on smartphones could assistidentification of parts and assessment of available

spares.

Safety and competence certification of personnel can bechecked using GPS location of personnel in relation to

work zones

Opportunities Close out

Voice recognition software provides for a means of more

accurately recording the work performed during repairs.

Photos and video frames taken during the repair job canbe stored for later repair reference.


16/20

Conclusions

Hand-held computing capabilities were evaluated and

ranked according to five main value drivers: cost, speed,

quality, safety and environment.

High value leverage points were identified as:

embedding photos and videos in work orders; scanning

of barcodes in order to display spare part status.

E-maintenance has the potential to significantly lift

maintenance labour productivity
