This document summarizes the findings of an IT development survey conducted in Israel. Some key findings include: - On average, Israeli companies spend about half their IT budgets on new development and half on maintenance. Definitions of development and maintenance varied between companies. - Most companies spend the most on coding, with lesser amounts spent on requirements, design, and testing. Testing budgets are lower when testing is part of the development organization. - Public and health sectors spend more on requirements while telecom spends more on testing. Various sectors use different project management methodologies. - Common metrics tracked include resources, time, features, lines of code, and bugs. Deployment and automation metrics are not commonly tracked.

STKI IT Development SurveyThe first IT development survey in Israel!Covering:Development vs. Maintenance budget Level of effort in development (requirements, design, code, testing, etc.)Level of effort in maintenance (bugs, new enhancements, infra. upgrades) Development internally, outsourced and package modificationRegulation vs. planned vs. unplannedDevelopment metricsQA organization, etc.Methodologies used in development process3
- 4. STKI IT Development surveyHow should you use this data:Look at the fine print – not all graphs are the same – including or excluding specific data according to the industry If you do not have all data as stated look at the ratios4
- 5. New Initiatives (“development”) vs. Running (“maintenance) SystemsIsraeli IT AverageSource: STKI SurveyThe actual question was: Which part from your development budget is directed to “development vs. maintenance”
- 6. About Development vs. MaintenanceDifferent companies has different takes. Example:“Development – 7 days or more with features that contribute to company profitability (not regulation)” “Everything is development except bugs correction or training support. Updating tables is development”Up to two months works is considered maintenance.

- 13. STKI IT Development Report11Public \ Government Spending more on the requirement stageTesting looks is much less mature.Therefore developers are dealing with testingSeveral organization are on the building stage of their testing units\proceduresHealth: more effort on design. Less effort on TestingTelecom: heavy investment in testing without specific budget to User Acceptance testingFinance (not banking): Heavy Management cost. Lots of investment in Design

What “contributes” to Software maintenance:Not all “minor improvements” are the same:One company might put all improvement in “development budget” while the other will put all “new development that is less than two weeks” “Infra” is SW adjustment to infrastructure changes – Win7, Oracle 11G, etc.14Source: STKI Survey

- 24. Selected Project Management metricsResource, Time, Features. And keeping track of it.LOC – line of codeNumber of mission accomplished in a month\period (normalized on mission size)Plan vs. actual in total effort spent per customer, project Net resources vs. overhead (courses, safety, illness-out of work)19
- 25. Selected Quality (bug\fault related) metrics. All per severity level# of bugs in testing and per man year, per K LOC# of escaping bugs (limited time in production) and per man year, per K LOC# of escaping bugs per # of bugs found in testingFirst time quality – in testing and in production20
- 26. Selected Quality (bug\fault related) metrics. All per severity level# of critical bugs per total bugs found in testing and in production# of requiring bugs (bugs that were not fixed at after first time)# of false positive bugs – bugs that were reported but actually did not exist21
- 27. Selected testing breath metricsPercent of code testedPercent of code with automatic tests22
- 28. Selected dev.\production process metricsHow many changes were introduced to a project while being developed (not relevant to Agile)Did the project followed all procedures How many times the project was put to production (if more than once- something went wrong…) # of LOC developed per specific feature (comparing two developing environment\supporting tools)23
- 29. Other development metricsISO metricsMaturity of reporting systems –how well people report to the activity\bug system (is reporting accurate, how often the reporting takes place, what is the delay between activity and the reporting). 24
