Hi, I am working as a technical architect with around 15 years of experience in the IT industry. I also have more than 3 years of managerial experience.
At the moment, I feel that I have hit a glass ceiling in terms of my career progression and want to explore the option of doing an Executive MBA in London. The aim is to gain knowledge and skills (specially in finance and accounting as they are my weak areas), develop a network and climb corporate ladder.

Based on my research, it looks like that LBS is possibly the best program out there in London. However If I have to choose between Warwick and Cass, what would be your recommendation? Are there any other programs you recommend?

Thanks.

LBS is absolutely the best EMBA in the UK. Chicago and ESCP are also strong options in London. The City EMBA [remember, the Cass name is gone] is better than Warwick for most people. Is the Warwick cohort even happening in London? Their campus in the Shard seems very hard to reopen with the current COVID restrictions, while City has a much larger estate.

What roles are you targeting? Do you want to become a CIO for example? For senior managerial roles in IT, strategy and marketing would probably be better areas to focus on than finance and accounting. Leadership skills are very important too.

Thanks for your input aslamo. In the long run, I am targetting for a C level position. If strategy, marketing and leadership are more critical skills, which business school would be the best to gain them?

What's your budget? The FT Exec MBA rankings have LBS, Oxford and Cambridge as the best schools in the UK followed by Warwick and City. The first three cost from £70-100k. 
I have a broadly similar background to you and aiming to be a CIO within 2-3 years. I decided on going down the MOOC route so am doing Oxford's Exec Leadership programme plus both the Maryland Core MBA and a Digital Leadership Micromasters with Boston University via EdX. Total cost is less than £5k. My approach isn't suitable for everyone but I suggest you consider whether you really need an actual MBA degree to be a CIO. I know a very large number of CIOs and less than 15% have an MBA. 

Yes, fair point - I've usually mentioned it in other posts. I don't really need the networking or career services as I have a big network of people in my sector including headhunters. I'm in my early 50s so am not going to get a massive salary jump even if I become a CIO. If you get an exec MBA from LBS, I'm sure it will open up lots of doors for you. I'm not familiar with their programme but take a look and see what their offering is in areas like soft skills development and leadership coaching. That is what will largely differentiate you as you rise in the IT ranks to senior management level.
