Exams Pre-Requisites

Successful completion of the 2 core training courses, and 2 of 8 specialist modules (one from each of two groups). 

The BCS-ISEB Diploma is the best recognised senior level Business Analysis certification in the UK - and is also increasing in popularity worldwide.

It is aimed at Business Analysts, Change Managers and senior IT professionals.  The  higher level ISEB qualifications demonstrate a holistic view of the components of the subject and the interactions between these components.  They are an important stepping stone to Chartered IT Professional status (CITP).

The Diploma requires successful completion of 2 core modules and 2 specialist modules. Typically these individual components are from within the same discipline, but may include Foundation or Practitioner training qualifications from other areas as appropriate.

Why Business Analysis

Successful organisations today understand how to integrate their IT systems and broader business processes to deliver differentiated products and services to their customers. At one level it may simply be about incremental quality improvement and cost savings; it may also involve more profound business re-engineering to support a step change in business model.

The skills to achieve this are complex and multidisciplinary. Twenty years ago the “systems analyst” documented existing paper based processes and then automated these through computerised systems. Today’s “business analysts” can be vital agents for change. They help identify change needs; capture and communicate requirements; evaluate and optimise business processes in line with organisational objectives; ensure defined requirements are delivered by IT; and they support the implementation process across different functional departments through to final business acceptance.


Becoming a Business Analyst


The Business Analyst needs to build practical experience and formal training which spans the above areas:
- Business objectives and processes including sales, operations and finance
- Information Systems analysis, design and deployment
- Communications

Whilst most Business Analysts will have an IT background this is not strictly necessary. Change managers, project managers and those with more general business skills may well be positioned to enhance their understanding of the more technical systems development and modelling skills. Moreover, it is increasingly common for Business Analysts to be positioned outside of the IT department – reflecting the pervasive and integral role of IT within today’s organisations. There is also a strong and growing use of Business Analysts in consultancy and interim management roles.

Few Business Analysts have started their career in this role. Most will have a foundation in areas such as systems development, technical analysis, operational research, quality improvement, or financial analysis. The usual requirement is for individuals to extend best practice skills into a range of areas where they are less proficient. This calls for practical and modular training rather than highly academic input.

The range of courses developed by the ISEB meets this need – and the associated exams provide independent validation of your capabilities.



BCS-ISEB (the British Computer Society) specialises in training and exams for IT professionals. BCS-ISEB exams cover 10 major IS areas and over 250,000 exams have been delivered globally.

Business Analysis and IS Consultancy is one of the most popular ISEB categories.There are a series of short courses with exams which can be selected according to training requirement.

Courses involve 2 to 4 days of training and an exam can be taken – either as part of the course or at a separate session later. The benefit of this modular approach is:

- Flexibility to concentrate on the topics you require
- Training inputs run alongside your work based experience
- Each module provides a well regarded certification

Those pursuing a career as a Business Analyst are likely to seek the ISEB Business Analysis Diploma. This requires completion of 2 core modules and 2 specialist options. The compulsory courses are Business Analysis Essentials and Requirements Engineering. The specialist modules are divided into two groups and candidates choose one from each. Candidates will then sit an oral exam with the ISEB which tests their ability to communicate effectively and to apply knowledge to their own work environment


1 - Do I need to pass multiple exams to obtain my Certificate?

No. Each module provides its own BCS-ISEB certification. It is only if you want the BCS-ISEB Diploma in Business Analysis that you need to pass four modules and sit the oral exam.

2- Which order should I take the modules?

It is not essential to take the modules in a given order. Most people prefer to take Business Analysis Practice or Requirements Engineering first since they deliver very practical skills and help provide a framework for broader understanding of Business Analysis.

3 - Is the Foundation in Business Analysis a pre-requisite?

The Foundation is a good starting point for those with little background in Business Analysis but it is not a pre-requisite.

4 - Are there fast track routes to obtaining the BCS Diploma?

Yes. Focus offers a 10 day residential course which covers all 4 modules and the price includes the exam fees for the four written exams. We also have a 5 day course which covers the requirements and exams for both Business Analysis Essentials and Requirements Engineering. And there are regular opportunities to take all four certificates in two successive weeks on non residential courses in London.

5 - Is it cheaper to book a package of courses to obtain the Diploma?

Yes. You will significantly reduce the cost of your training and exams if you are able to book and pay for a series of modular courses in advance. The package price, course dates and scope will vary by provider. Contact Focus on enquiries@focus-ontraining.co.uk to find out what options are available.

6 - Why does the course duration differ for the same modular course?

The BCS-ISEB recommends a minimum number of hours training for a given syllabus but it is up to training providers to set the course length according to the needs of delegates. This means that course durations vary; the course content will be consistent and we recommend that if you have a choice, you select according to your confidence level in the subject matter.

7 - When is the Diploma exam taken?

The oral exam is taken once the appropriate modules have been completed. In most cases, this exam needs to be booked directly with the BCS. Please check the course details on the Focus website.

8 - Is the exam fee included in the price of a course?

The fee for the Diploma oral exam is generally not included in any course fee, but please check the course details on the Focus website

On the individual course modules, Focus prices include the exam fee (except where the exam is arranged as a separate event).
