AI development
If your challenging tech initiative may take a significant amount of time, it is better to hire a dedicated development team as a strategic partner to mitigate any risks.
Design services
Unclear IT project paths and conflicting requirements are a serious threat. Mitigate these risks with an Agile development team from Andersen that you can assemble and manage.
Legacy modernization
IT initiatives involving several tech stacks are hard to implement unless you have a dedicated software development team possessing a mastery of all tools required and working under your in-house guidance.
MVP development
Rapidly changing requirements, constantly shifting priorities, and an unstable overall environment make minimum viable product delivery projects risky without a highly skilled dedicated development team you can rely on.

FAQ
The main potential problems with off-the-shelf solutions are self-evident. First, although obtaining and starting to use such software is quicker than waiting for a custom suite to be finalized, you will either have to tailor an off-the-shelf product to your business processes or adapt workflows to the product. Both options are time-consuming and costly, nullifying the advantages of off-the-shelf software. Second, by investing resources in custom software solutions, you assume full ownership of them. Off-the-shelf suites imply license payments, subscription fees, and other extra expenditures. Finally, if you opt for custom software, there will be no significant limits in terms of scaling it and integrating it with other digital products, both already existing and future ones. In the case of off-the-shelf software, restrictions imposed by its vendor will always remain in place.
