ROI and TCO are two well known IT buzzwords. They mean Return On Investment and Total Cost of Ownership (check the links for more technical descriptions). The first one tries to measure how much you earn or lose by investing on something (software product or solution in IT world). The second one tries to be a measure of the sum of costs you have when you decide to buy and use a software product or solution. For the technical staff these two measures are not the most important aspects. Usually we just like or dislike a product period!
But the decisions and choices usually aren't done by technical staff. Today the decisions are taken by people who have tight budgets and that need to show to corporate management that they are using the company's money properly. In other words, people who do and must care about TCO and ROI.
And many times we hear that Informix is nice technically (easy to work with, robust, scalable etc.), but that it's hard to convince higher management to use it (there are still ghosts from the past and FUD spread by competition).
Well, now we have two consulting firms studies precisely about these two topics.
The first comes from Forrester Consulting and analyses the costs, benefits and ROI of implementing Informix. Needless to say it concludes that you actually can save money while investing in Informix, and it explains why. The study was based on a real company.
The second come from ITG group and compares the TCO of Informix vs Microsoft SQL Server for mid sized companies. It's based on a survey with ten's of participants and the conclusions are, as you might expect, favorable to Informix (important to note that MS SQL Server has a reputation of being "economic", so we could let us think that it would be even better for other competitors)
The studies can be freely obtained from IBM website, and as usual you need to fill some data. I know, I know.... this is always annoying and we could arguably consider that this should be only a link to allow quick access to that, but honestly it will take one minute to fill the form, and you have the usual option to request that you won't be bothered (no emails, phone calls etc.)
Don't let it discourage you. The studies are well worth the effort. Their URLs are:

Vers�o Portuguesa:
ROI e TCO s�o duas palavras muito em voga no mundo das TI. Qurem dizer Return On Investment (Retorno do investimento) e Total Cost of Ownership (Custo total da posse) (verifique os links para explica��es mais t�cnicas - e ainda mais detalhadas na vers�o Inglesa). O primeiro tenta medir quanto se ganha ou perde ao investir em algo (produto ou solu��o de software no mundo das TI). O segundo tenta ser uma medida da soma de custos que teremos quando decidimos usar um produto ou solu��o de software. Para o pessoal t�cnico estas medidas n�o s�o os aspectos mais importantes. Normalmente n�s apenas gostamos ou n�o e ponto final!
Mas as decis�es e escolhas normalmente n�o s�o feitas pelo pessoal t�cnico. Hoje em dia as decis�es s�o tomadas por pessoas que t�m or�amentos apertados e que sentem a necessidade de mostrar � administra��o das empresas que est�o a usar o dinheiro da companhia criteriosamente. Por outras palavras, pessoas que se preocupam e devem preocupar com o TCO e ROI.
E muitas vezes ouvimos dizer que o Informix � muito bom tecnicamente (simples, f�cil de usar, fi�vel etc.), mas que � dif�cil convencer a gest�o a us�-lo (ainda existem fantasmas do passado e FUD espalhado pela concorr�ncia)-
Bom, mas agora temos dois estudos de duas empresas de consultoria precisamente sobre estes t�picos.
O primeiro vem da Forrester Consulting e analisa os custos, benef�cios e ROI de implementar Informix. Escusado ser� dizer que conclu� que na realidade estamos a poupar dinheiro ao investir em Informix, e explica porqu�. O estudo foi baseado num caso real.
O segundo vem da ITG Group e compara o TCO do Informix vs Microsoft SQL Server para m�dias empresas. � baseado num inqu�rito com dezenas de participantes e as conclus�es s�o, como seria de esperar, favor�veis ao Informix (� importante notar que o MS SQL Server tem a reputa��o de ser "econ�mico", por isso poder�amos deixar-nos pensar que seria ainda mais favor�vel comparando com outros concorrentes)
Os estudos podem ser obtidos gratuitamente no website da IBM, e como � habitual necessitamos de preencher alguns dados. Sim, eu sei, eu sei.... Isto � sempre irritante e � discut�vel de n�o deveria ser apenas uma quest�o de clicar num link para aceder aos estudos, mas honestamente n�o demora mais de um minuto a preencher o formul�rio e tem as op��es habituais para que n�o sejamos incomodados (nada de emails ou chamadas telef�nicas etc.)
N�o deixe que isso o desencorage. Os estudos merecem bem este pequeno esfor�o. Os seus endere�os s�o:
