A Quick Checklist Before You Finalise
Before you sit down and spend hours researching which to pick as per your requirements, we are here to help you easy your task. You can use this list to filter and select the software development companies in UK and London easily-
Experience
- Look at their years of experience and the domain expertise. You can browse through the 4-5 case studies and look at their past work for your field.
Communication
- You can connect with the teams and question them about the communication process. Would they keep you in the loop? How frequently would you like to receive updates? Would there be transparency throughout the project?
QA testing
- From the initial stage to the launch, question them about the integration tests and automation, as at the time of launch, facing bugs is not something you want, right?
IP, ownership & licensing
- While communicating, ensure that you control your code and usage rights. After all, bespoke software solutions have this at their core- the right to ownership.
Post-Launch Support
- You can ask the professionals whether there will be any support after the launch. How and for how long would post-launch support be provided? Would it be included in the package? Would it be charged extra?
Guess what: all these requirements- domain expertise, transparency, QA testing, and post-launch support- are easily met by IIH Global.
