Potential Risks

The test manager is also responsible for identification of  Potential Risks that might impact testing. Some of the primary testing risks include:

Not Enough Training/Lack of Test Competency
The majority of IT personnel have not been formally trained in testing, and only about half of full-time independent testing personnel have been trained in testing techniques. This causes a great deal of misunderstanding and misapplication of testing techniques.

Us versus Them Mentality
This common problem arises when developers and testers are on opposite sides of the testing issue. Each feels that it is “out to get” the other. Often, the political infighting takes up energy, sidetracks the project, and accomplishes little except to negatively impact relationships.

Lack of Test Tools
IT management may have the attitude that test tools are a luxury. Manual testing can be an overwhelming task. Although more than just tools are needed, trying to test effectively without tools is like trying to dig a trench with a spoon.

Lack of Management Understanding and Support of Testing
Support for testing must come from the top, otherwise staff will not take the job seriously and testers’ morale will suffer. Management support goes beyond financial provisions; management must also make the tough calls to deliver the software on time with defects or take a little longer and do the job right.

Lack of Customer and User Involvement
Users and customers may be shut out of the testing process, or perhaps they don’t want to be involved. Users and customers play one of the most critical roles in testing; making sure the software works from a business perspective.

Not Enough Schedule or Budget for Testing
This is a common complaint. The challenge is to prioritize the plan to test the right things in the given time.

Over Reliance on Independent Testers
Sometimes called the “throw it over the wall” syndrome, developers know that independent testers will check their work, so they focus on coding and let the testers do the testing. Unfortunately, this results in higher defect levels and longer testing times.

Rapid Change
 In some technologies, especially Rapid Application Development (RAD), the software is created and modified faster than the testers can test it. This highlights the need for automation, but also for version and release management.

Testers are in A Lose-Lose Situation
On the one hand, if the testers report too many defects, they are blamed for delaying the project. Conversely, if the testers do not find the critical defects, they are blamed for poor quality.

Having to Say “No”
Having to say, “No, the software is not ready for production,” is the single toughest dilemma for testers. Nobody on the project likes to hear that and frequently testers succumb to the pressures of schedule and cost.

Test Environment
The work environment is not conducive to effective and efficient testing.

New technology
The new focus on client/server, Intranet, and Internet applications has introduced even more risk to the test process. These multi-tiered systems are more complex than traditional mainframe systems, and therefore have a higher level of risk associated with their testing and implementation. Security, performance, availability, complex component integration, and a team new to the technology are just a few of these new risk factors.

New developmental processes
Along with these new delivery platforms come new methods for software development. Project teams have moved away from traditional “waterfall” methods, and follow a much more iterative approach to development and delivery. An integral part of this iterative approach is that testing activities are more integrated across the development cycle than before. Traditional system testing is not just conducted at the end of development, but may be conducted multiple times throughout the project for major components, and then completed once all development is complete.
