Rescue or redesign software? Decision aid

• *Your software project is in a deep crisis. ** Dates are torn, costs explode and quality is in the basement. You are facing a fundamental decision with far-reaching consequences: try to save the sinking ship or give it up and start with a complete new development? This decision should not be taken out of the abdomen. It requires a cool, data-based analysis.

The idea of a new development is often tempting. A green meadow where you can work with the latest technologies and without the old loads of the failed project.

But this path is paved with considerable risks, which are often underestimated.

• Low initial investment

• Faster time-to-market

• Consistent knowledge is preserved

• Risk often more calculable

• *40-60% cheaper *

New development

• High initial investment

• Longer development time

• Risk of loss of knowledge

• danger of repeating identical errors

• chance of modern technology

The underestimated power of salvation

Short: A professional software review aims to maximize the investments already made.

A professional software review aims to maximize the investments already made. Industry analyses show that a rescue ** can save up to 40-60% of the cost of a new development**.

The focus is to consider the existing code as a valuable asset that can be saved and improved.

The rescue score: A quantitative decision-making aid

Short: To make a more objective decision, you can use the following checklist.

To make a more objective decision, you can use the following checklist. Rate each factor on a scale of 1 (does not apply) to 5 (does fully apply).

Score 30-40: A rescue is most likely the better option. Score 20-29: The decision is not clear. A detailed analysis is necessary.

Score 8-19: A new development could be the more sensible alternative.
