STKI IT Development Survey
The 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 modification
Regulation vs. planned vs. unplanned
Development metrics
QA organization, etc.
Methodologies used in development process

STKI IT Development survey
How 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 ratios
4

New Initiatives (“development”) vs. Running (“maintenance) Systems
Israeli IT Average
Source: STKI Survey
The actual question was: Which part from your development budget is directed to “development vs. maintenance”

About Development vs. Maintenance
Different 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.

Spending from IT Budget
Testing including acceptance testing (effort by IT)
Development - means developers effort and not necessarily just development (might include unit testing and other testing)

Public Government
Spending more on the requirement stage
Testing looks is much less mature.
Therefore developers are dealing with testing
Several organization are on the building stage of their testing unitsprocedures
Health: more effort on design. Less effort on Testing
Telecom: heavy investment in testing without specific budget to User Acceptance testing
Finance (not banking): Heavy Management cost. Lots of investment in Design

Testing Focus
Factors Influencing QA:
Internal SW development
SW is an integral part of the org. services to customers
Regulation
Established methodologies (CMMI, ISO)
(Insurance & Credit Cards)
Source: STKI Survey

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.

Metrics used
Source: STKI Survey
Each respondent could add several metrics
17

Metrics used – what is missing?
Deployment Hatmaa metrics are missing!
18

Selected Project Management metrics
Resource, Time, Features. And keeping track of it.
LOC – line of code
Number of mission accomplished in a monthperiod (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

Selected Quality (bugfault 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 testing
First time quality – in testing and in production
20

Selected Quality (bugfault 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 exist
21

Selected testing breath metrics
Percent of code tested
Percent of code with automatic tests
22

Selected dev.production process metrics
How 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 environmentsupporting tools)
23

Other development metrics
ISO metrics
Maturity of reporting systems –how well people report to the activitybug system (is reporting accurate, how often the reporting takes place, what is the delay between activity and the reporting).
24

Organization Position of QA
Source: STKI Survey

Show me the QA money!
When QA is part of development the testing budget is lower – 38% difference! (at average)
26

Profile of your testing personnel
Rising interest in Israeli Nearshore due to their subsidization by the Gov.
Source: STKI Survey

Which Methodology is used
Counted even if used in few projects or experimenting (for example “using iterative only in Internet projects” or “experimenting agile in small projects”
CMMI is more common in Banking
ISO certifications used are ISO9001:2008 and 9002.
