IT has become part of your employees’ daily life
Your employees have become
computer literate. And reviewed or
rated apps are available 24/7.

Your employees are creative and involved
Trying to stop our employees from
creatively managing their work is like
pushing water uphill with a rake.

3. API’s
4. Security
5. Privacy
6. Vendor lock-in

2. Data and file formats
• Prezi is a great tool, but can you REALLY
combine it with Powerpoint (corporate standard)?
• Your home-baked customer switching app is
great, but does it connect to (the Dutch legally
obliged) EDINE messaging services?
• Are you sure that the transactional integrity in the
ERP part of your BigSQL back-end is OK?

3. API’s

Quote from James Governor, RedMonk for TechTarget / Search SOA
‘it is like API management is the new SOA’

4. Security = goal - risk

Counter measure 1: complexity reduction
Adaptation of material from Roger Sessions, Object Watch. Productivity comparison: ISBSG
Total system complexity is a function of the number of
business functions, the number of system connections and
complexity of the platform. Calculation: bf3.1+ sc3.1+ pc3.1 16

Counter measure 4: stop fortification, be resilient
19
Resilience can be obtained by moving away from typical barrier enhancement
risk-measures. Consider the following options:
• Ignore, the ostrich ‘see-no-evil-hear-no-evil’ tactic;
• Accept, the potential impact of some risks may be deemed acceptable to your organization;
• Reduce, e.g. the potential impact or probability of occurrence of a risk, like the banking app;
• Transfer, use insurance or subcontracting to transfer potential consequences of risk;
• Avoid, not entering the type of business that may incur potential risk impact deemed too high;
• Exploit, risk is also an opportunity and high risk investments may yield high returns.

Counter measure 5: Educate

You cannot stop water from flowing, but you CAN
educate staff on privacy concerns.
