Loan Application Process Flow

All arriving input loan application forms $($hereafter $$forms$)$ to a process undergo a task T$1(3$ minutes$)$ performed by Staff A$.$ The forms after the task T$1$ is separated into two parts Ia$,$ Ib$.$ Staff B performs T$2(2$ minutes$)$ on Ia and Staff C performs task T$3(4$ minutes$)$ on Ib$.$ After T$2$ and T$3,$ Ia and Ib are joined and goes through task T$4$ which can be performed either by Staff D or Staff E$.$ Staff D takes $5$ minutes while Staff E takes $4$minutes to perform task T$4.$ After T$4,$ the input is again re$-$separated into Ia and Ib$.$ Staff F performs T$5(2$ minutes$)$ on Ia and Staff G performs task T$6(5$ minutes$)$ on Ib$.$ After T$5$ and T$6,$ Ia and Ib are joined and the combined form leaves the process. What is the cycle time $($in minutes$)$ for the process?
