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.

Software Recovery

• 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

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).

Review checklist

FactorFr. Code quality Is it stable, well written parts in the code? Architecture Is the basic architecture still viable? Domain knowledge Does complex business logic in the code? Team knowledge Is it team members with deep understanding? Investition Wurde is already investing a lot of budget? Time-to-Market Is a fast launch critical? Data Does it contain critical data whose migration is complex?

Is the software deeply integrated into other systems?

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

A detailed review is needed. Score 8-19: A new development could be the more sensible alternative.
