Having testers engaged throughout every stage of the

project benefits the business in many ways providing

a different focus and insight, which allows issues to

be addressed early and consequently cheaply!

Benefits of testing Results of poor

test engagementProblems found during roll

out:• Delays if issues arise in training

and site implementation when

users find functionality is missing,

wrong or has bugs

• Delays in implementation in the

field while problem are investigated

and resolved

• independent check on the

development life cycle from

business case to live operation

• Find issues early to reduce cost

• Reduce risk leakage between

phases

• Ensuring adequate entry and exit

criteria are set and observed at

each stage of development and

testing

Problems found in

live operation:•Reputational damage to

IT eroding trust and

adversely affecting

confidence in future

work

•Significant additional

project or support

costs while issues are

resolved

•Additional manual work

in the business or IT

support to implement

workarounds

•Disruption to other

development projects

due to support

requests

•Delayed and/or

reduced Return on

Investment

•Risk of investigation of

the issues by auditors

and/or regulatory

bodies (especially if

issues arise in billing

or poor treatment of

consumers).

• Prevent the costs of risk

mitigation slipping to

later stage of projects

• Improve the quality of

requirements and design

• Assure

business/functional

requirements are

unambiguous,

measureable and testable

• Testers can also help

review designs

(architecture, database

structures) and even

code

• Be the “glue” across the

project. Testers have to

engage with a project

from start to finish. No-

one else gets that

detailed end-to-end view

or can add value to all

activities.
