Today, IBM i applications are facing several challenges. IBM i \/ AS400 systems, many of which were originally written in RPG or COBOL, are robust and reliable, but they often lack the capabilities today\u2019s users expect. <\/p>\n
Over the years, IBM iSeries applications have been adapted to meet new business requirements. Software engineers have not only fixed bugs but also updated IBM i systems to meet new regulations as well as improve their performance. These adaptations happened over decades leading in many cases led to a complex and hard-to-maintain codebase. Often, there is no or minimum documentation about an app, as developers that originally developed an IBM i application have already retired or will retire within the current decade. This makes it hard for new software developers to fully understand the code and make user-driven changes without breaking the whole system. Eventually, the cost to maintain IBM i \/ AS400 applications has gotten quite high: in some cases, over 80% of IT budgets<\/a> have been allocated to software maintenance activities instead of to delivering new customer-facing solutions. <\/p>\n\n\t\t\t\t
