Final answer:
A disadvantage of building your own in-house software solution is the likelihood of incurring fewer software 'bugs' and longer development time. Additionally, training must be developed in-house, which requires additional resources A and B (option d)
Step-by-step explanation:
A disadvantage to building your own in-house software solution is that it can result in fewer software 'bugs' incurred. When developing software in-house, there is a higher likelihood of encountering software bugs due to limited testing and debugging resources. On the other hand, if a company chooses to outsource software development to a professional firm, they often have dedicated quality assurance teams and robust testing processes in place, reducing the number of bugs in the final product.
Another disadvantage is that it may lead to a longer development time compared to using pre-built software solutions or outsourcing the development to experts. Developing software from scratch requires significant time and effort to design, code, test, and iterate on the solution to meet the specific needs of the business. In contrast, pre-built solutions or outsourcing can save time by leveraging existing frameworks and expertise.
Lastly, training must be developed in-house when building custom software solutions. This means that the company needs to allocate resources for training employees on using and maintaining the software. On the contrary, with off-the-shelf software or outsourced development, training and support are often provided by the software vendors or development teams, which can be more convenient and cost-effective for the company.
Therefore, the correct option is D. A and B (fewer software 'bugs' incurred and shorter development time).
