› “Increasing complexity in networks”
› "Most of the Company’s R&D
investment is in software
development. With smarter
software, algorithms, processes and
designs, Ericsson secures that its
networks and solutions have the
industry’s best performance.”

Where to use to ASD:Suite?

What is New?
› Compared to earlier Model Driven Development attempts with “automated” code generation techniques the ASD:Suite
› Offers error free software by verification based on
formal methods – Where the formal methods are hidden from the
developers
› Works with legacy software based on it’s interface modeling technique
– No need to first model the complete system, just start small
› Proven to work in the Ericsson environment with products deployed at customers !
– And the engineers like it !!!
10
› First ASD project (VPN-IMS
GW), ready 1 month earlier
– 4 months instead of 5 months
– 20% lead time reduction
› All later projects, delivery on
time and earlier than
conventional methods
Time-to-Market
On Time Delivery
-20% lead time
11
Predictability
› Improved precision on effort and cost
estimation, by a factor 2 (at least)
› Measurable process:
– Alternative to man-hour estimates based on
eLoCs
– Fast and easy comparison between number of
events and event sources between projects
› ASD forces an early grip on requirements,
leading to a faster knowledge build-up in
the early phase of the project

› Faster results with maximum design freedom
– ASD enables us to rapidly explore architecture & design alternatives,
allowing us to find the most optimal & effective overall design for the
product

› ASD proves to be a strong motivation
– Abstract approach and focus on architecture
and design
– Immediate feedback on design
› With a relatively small team, drive for fast
and illustrative results
– Maintain design freedom and full creativity,
keeping the creative work (core IP)
– Improved ability to outsource non-core
components
› Having fun and being able to make a
difference
