ITK Method

Methodology to evaluate complexity and cost of developing and maintaining application software for creating information systems (Method CETIN) - this is an algorithmic model assessment value software, developed by a consortium of Kazakh IT companies: Kazakhstan Association of IT-companies Company System Studies "Factor" and JSC "National Information Technologies.
Method allows assessment of complexity and cost of development of oftwarein the early stages and is based on an assessment of the functional size of software.

History

The first edition of the Kazakh techniques appeared in 1994 as in "Methods of assessing complexity of information systems of the Ministry of Finance of the Republic of Kazakhstan". The principal method was based on the standardization work on a project (the creation of the queue system, the development and implementation of the project functional complex tasks, linking projects, project monitoring, the use of a PC for debugging and commissioning). The disadvantages were the methods use the principle of a cascade model of the software lifecycle and experience of a single developer.

In 2005 in NIT with Research Institute of Economy and Informatization of transport, telecommunications have developed a "methodology to assess the complexity and cost of developing and maintaining information systems." The method was based on 2005 edition of evaluating the functional size of a model of UML-diagrams of the information system, assessment of functional complexity of the size and development time estimates based on the model COCOMO. The main drawback of techniques, from whom she has not received Shirokova distribution is that technique was not adopted as a single regulatory document cost estimates for public IP razrabokti organmov. Another drawback was the lack of research on the collection of statistical databases based on IT development in Kazakhstan to confirm the partial adjustment factors.

In early 2010 and were re-work continued to refine techniques. Then at the second congress of IT-companies of Kazakhstan in the report Gabbasov M Pustovoitenko V have been identified requirements for the new version of the Methodology.

Work continued on methods companies JSC "National Information Technologies, Kazakhstan Association of IT-companies and Company System Studies "Factor". Reworked version techniques presented in August 2011 as well.

Order assessing complexity of software development

Procedure for evaluating the development of middleware complexity represented by the following steps:
1. Evaluation of the functional size of the developed IP;
2. Assessment of the basic design complexity of the PES;
3. Determining the values of correction factors labor development and maintenance of fire suppression;
4. Calculation of complexity, taking into account the development of the PES adjustment factors;
5. Estimation of the development of middleware;
6. Adjustment of labor in developing middleware reduction of development;
7. Assessment of the cost of developing the middleware.

Evaluation of the functional size of the developed IP

Evaluation of the functional size of the IP is based on a model of information system and functional requirements of users.
Functional size of IP given by a set of five elements, each element of which is the appropriate functional unit.
Functional units:
* The number of use cases - C
* Number of object types - E
* The number of properties of object types - T
* The number of interactions between types of objects - I
* The number of node types - N

Functional size is designated - SIZE =

Assessment basic labor

Basic complexity of software development is based on the evaluation of complexity of each software development process. As the development processes used by the process model Rational Unified Process.
Basic labor Sj development process with index j is calculated as follows:
Sj = 1 / 165 • technique CETIN
