The document discusses software development rates versus the price of function points based on a study of projects from 2014 and 2012. It finds that clients who implemented estimation models and productivity controls saw more homogeneous function point pricing across providers compared to 2012. Three case studies are presented showing how introducing competition between providers, delocalizing providers to lower cost locations, and implementing productivity SLAs reduced function point prices for clients by up to 44% while rates remained similar. The conclusions are that centralized estimation, productivity monitoring, and competition among providers are more effective than solely focusing on rates to influence function point pricing.

Software Rates vs Price of
Function Points: A cost
analysis
Goals of the presentation
Nowadays, in Software Development Contracts the key elements determining
the price are: the Rate and the Effort.
The possibility to measure the quantity of software produced (the size in
Function Points) allows us to assess whether there is a logical connection
between the price of the projects and the software actually produced.
The main goal of this presentation is to show what happens with the FP
price in several scenarios:
G1. Implementing estimation models.
G2. Implementing productivity models.
G3. Introducing new competitors in a productivity model.
G4. De-localizing providers.

Background
Over the last seven years, LEDAmc has managed the productivity of more than 12,000
development projects of 10 significant clients in Spain (mostly telecommunication and
financial companies). They were mainly small enhancement projects.
The main goal of the measures is to control large contracts of Adaptive Maintenances,
which involves the highest percentage of our clients’ development budget.
In 2012 LEDAmc developed a benchmarking study with some of these projects (we
selected 3,405). The purpose of the study was to analyze the relationship between the
rates of the different software providers and the price of the Function Point that they
were offering their clients. This study was presented:
•In the UKSMA conference in October 2012
•An updated study, in the IT Confidence Conference in Rio, in October 2013.
5. 5IT Confidence 2014 – October 22, 2014 http://itconfidence2014.wordpress.com
Background
The basic numbers of the 2012 sample were:
•10 Clients
•14 Providers
•3,405 Projects
•196,356 UFP
•2,168,192 Hours
•69,926,907 Million Euros
And the main conclusions were:
Pressure to lower rates ends up in lower productivity and higher FP price.
There is not a logical relationship between Rates and FP Price.
The performance of the providers changes dramatically among clients.
Clients with only one development provider have the highest FP Price.

Objective
LEDAmc has been continuously working for most of those clients, implementing Software
Development Productivity Models over the last two years.
Our productivity benchmarking data base has grown: It has more data for the same
clients and new clients have been included.
The main goal of this presentation is to show what has happened in these two years with
clients who have worked hard to improve their software development productivity.
We will first explain the general evolution of the Function Point Price for those clients,
comparing 2012 and 2014 benchmarks.
Afterwards, we will focus on three case studies that are especially significant.
Finally, we will draw conclusions on the economics of software management, based on
our results.

2014 vs 2012 benchmarking
Conclusions
The results are homogeneous on a client basis because they have implemented
estimation or productivity control models that allow them control the FP price.
Because there is no transparency in software development and the public FP price does
not exist in the market, the FP price stills remains very different among the clients.
The natural differences of the systems architectures and processes should not imply
such FP price differences.
… now we will present some case studies highlighting the change that has been
produced for these clients who have introduced control systems.

Case studies
During 2013, the implementation of a centralized mechanism of estimation control has
allowed to objectively contrast the costs offered by providers with corporate cost
strategies.
It includes functional sizing, as well as other sizing methods (for parametrization,
technical changes, test support,..)
Benchmarking studies helped establish a cost strategy and a target price for FP .
Introducing a new development provider fosters competitiveness among providers and
helps establish a FP price within market values.

The client strategy was to proceed to the de-localization of the providers to a
typical outsourced model introducing new development providers with lower rates.
The client also decided to create an in-house development team in order to
preserve and extend the know-how.

During 2012 the client implemented a productivity control for maintenance
development.
An annual productivity SLA for all the providers was established.
The client also implemented a productivity and quality providers ranking.
Every two months the client presented to the providers their position in the ranking.

Conclusions
1. It is relatively easy to influence FP price. The main levers are:
>>> A centralized estimation control
>>> A development productivity control
>>> Several providers in competition
2. Working on those key elements the results are much better than working only
on the rates:
>>> The behavior of the unit cost of production (FP price) is more homogeneous.
>>> The cost of the development process can be controlled.
3. Diversification of providers with joint management results in a better uniformity
of the FP price.
