12. The waterfall model is a sequential design process, used in software develop-
ment processes. Progress is seen as flowing steadily downwards (like a
waterfall) through the phases of conception, initiation, analysis, design,
construction, testing, production/implementation and maintenance.
The waterfall development model originates in the manufacturing and con-
struction industries: highly structured physical environments in which
after-the-fact changes are prohibitively costly, if not impossible. Since no formal
software development methodologies existed at the time, this hardware-oriented
model was simply adapted for software development.
METHODOLOGIES
About our processes
AGILE (SCRUM)
WATERFALL MODEL
Scrum is a team process that begins when a client needs a product. The Scrum
team includes three roles: product owner, ScrumMaster, and members of the
development team. The product is built incrementally over a series of short time
periods - sprints. A sprint is a fixed period, up to four weeks long but with a
preference toward shorter intervals.
During each sprint, the Scrum team builds and delivers a product increment.
Each increment is a recognizable, visibly improved, operating subset of the
product. It meets understood acceptance criteria and is built to a level of quality
referred to as the Definition of Done.

13. PRICING MODELS
How we work
FIXED PRICE TIME & MATERIAL DEDICATED TEAM
IDEAL FOR
Small- and mid-sized projects with no unknowns and
clearly defined deadlines.
Such a model is used when the customer does not
want to delve into technical details of the project and
plans to get ready-made solution within the
determined project budget and timeline.
IDEAL FOR
Medium and large projects with many unknowns
and flexible project scope or for the projects in their
maintenance phase.
This business model is quite flexible and highly
efficient when it is hard to predict the final cost of
the project and when the customer's requirements
depend on different factors.
IDEAL FOR
Projects constantly innovating and developing and
having own project management staff. If you have
your own management team and well-defined project
idea, GNS can provide you with dedicated team of
designers, developers and QA who will work
particularly on your project from its very start up to
release.
This low-risk model assures that the final
solution will match the requirements and
correspond the agreed scope. At the same
time we meet the expected timelines and
deliverables offering you reasonable project
cost.
There is a certain risk for the client in case:
- it is hard to predict the precise cost, time
limits, efforts to be spent;
- the development process needs control and
improvement at any stage.
It means Time & Material or Dedicated Team
Business Model is more desirable.
Time & Material is one of the most efficient
pricing models. It offers enormous flexibility
and control over your budget. Utilizing this
model with consumer-oriented projects
enables you to:
- quickly and efficiently respond to the
market trends;
- deliver solution with minimum time-to-
market.
If you want to get more control over
the project budget or define the time limits
more clearly, you should choose another
pricing model: Dedicated Team or Fixed
Price.
Dedicated Team engagement model allows
you to manage our engineering team as
your own development department or as an
extension to it.
We either form your team out of our
development staff or provide a team with an
experienced project manager.

Electronic platform for transparent trade negotiation for Over-The-
Counter (OTC) transactions
Result:
• High available, autoscale and guarantee delivery WCF services: like in
all systems related to finance sphere services must be close as much
as possible to 100% work time and even no single message might be
missed. Due to highly loading of services they should be scalable to
satisfy performance needs.
• Distributed database on different engines: our app works with data that
sometimes stored in multiple databases like main database on SQL
Server, clients’ databases that might be any database and local
database on sqlite. Operations should go within single transaction
between all DBs to keep data in consistent state.
• Real-time data delivery: it’s important for trades operations like bids
and asks that must be shown to all users in real-time.

and communicate through secure channel only. To achieve this we
use Windows Identity Foundation that was fully integrated into .net 4.5.
