I don't want to follow suit in the argument which is more difficult between IT and Accounting. But I can't help myself but to defend accounting. I'm handling an Asisstant Managerial role in a Foreign Multinational Company doing business here in the Philiippines. My section is handling Business Process Improvement and I have an IT person reporting to me. Also, I have an Accountant who handles the administration of one of our Financial Reporting System (e.g. updating of business rules using VB Script, creating webforms, etc.). On top of that we also assist in difference Accounting and Financial Analysis using different models (e.g. Statistical model from simple regression to Structural Time Series Model. For example SWDA, Price Elasticity, Optimization Model).
My take on this is "Accounting and Finance" is very difficult. When I say difficult I mean the higher accounting and finance subject. It involves Statistics and Calculus. For example, how would you know the highest profit attainable if you don't know quantitative techniques such as Simplex Model or if you don't know Derivative Calculus? Hope someone can reply to this. But I can't say that IT is also not difficult. I can say I'm good in programming and IT folks need Accounting or Fianance People in doing System's Analysis. But we accounting people also needs IT, otherwise imagine the tons of data we need to analyze and we need their logical skills in coming up with a quicker solutions. Hope my take on this will help in this forum.
P.S. By the way, there are other areas of Finance and Accounting that needs knowledge of law including its interpretation. For example Tax. There are also areas of IT that needs higher mathematical skills. So I guess its like comparing an apple to an orange. In the end, they need each other and almost always overlapping. They are like an apple and an orange needed in one particular recipe.
