When an urgent change must be made quickly, what approach is typically taken regarding requirements and design documentation?

All other work stops until requirements and design documents are fully revised

The system is taken offline permanently until a complete redesign is finished

A new contract is signed with an external vendor before any code is touched

An emergency fix is made directly to the program rather than first updating the requirements and design

Risk of Documentation Drift

1 pts

volume_mute

What is the danger described when emergency fixes accumulate over time without updating documentation?

Customers will automatically receive a refund for undocumented changes

The compiler will refuse to build the software after three undocumented fixes

The original change may eventually be forgotten and the system documentation and code never realigned

Emergency fixes are illegal under most national software regulations

Minimal Documentation Argument

1 pts

volume_mute

How does the problem of maintaining multiple representations of a system (requirements, design, code) relate to agile development philosophy?

It demonstrates that documentation should always be written before any code

It shows that only plan-based methods can avoid emergency fixes

It is one of the arguments for minimal documentation, which is fundamental to agile development processes

It proves that agile development never produces any usable software

Emergency Repairs and Software Ageing

1 pts

volume_mute

How do emergency system repairs typically affect the long-term maintainability of a software system?

They always improve system structure because they force code review

They permanently fix all related issues so no further changes are needed in that area

They tend to accelerate the process of software ageing, making future changes progressively more difficult and increasing maintenance costs

They have no measurable effect on the system's future maintainability
