To produce high quality Architectural or Engineering outcome, one needs to interview many and finally hire experienced architect(s) and engineer(s) which, in financial terms, means high salaries and much more direct and indirect expenses.
Imagine what would happen when the projects are over and therefore there is a gap without any income yet you should continue your compensation.
But with access to a reliable outsourcing body, your overhead expenses will be dramatically reduced. This means you will pay whenever you have another project. As far as your key human resource is concerned, there is an expense only when there is an income.
As much as you can reduce the number of people on your pay roll, your other indirect costs will also decrease. For example, you will need a relatively smaller office space, less number of computers and etc.
This means you will Pay Per Project rather than to Pay Per Payroll.
You hire a certain number of professional staff based on your average annual workload neither according to the peak nor to of its rock-bottom. Therefore, during the peak of your workload, you will encounter difficulties to deliver the projects within a normal schedule or even worse, you might miss the deadlines.
On top of that, during the peak, a great deal of your energy will be directed towards time management making sure that everyone is working and delivering according to the schedule.
Outsourcing will provide you with a scalable number of staff. In other words, if one project can be delivered in a matter of a week, 3 projects of similar size can also be delivered in the same period.
It also helps you to avoid over-times and other incentives to keep up your hired staff's motivation.
High Quality will only be achieved through highly trained professionals and everybody in the field knows the challenges of finding, hiring, maintaining and motivating the professionals.
A professional expects a relatively high salary and in order for him or her to grow, a diverse range of projects with a variety of technical challenges is needed. It doesn't make sense for one to hire a full time professional unless he or she is able to feed that person with a continuous flow of workload on a regular manner. Therefore, the times that your company is running with a low workload, the presence of your professionals is rather an obstacle to be dealt with.
Instead, an outsourcing partner, will distribute the workload among many professionals who are available at that certain time and enables you to be free of/ less dependent on the presence of full time professionals. This way, you have professionals at your service only when you need them and therefore your quality is always secured.
