An Enterprise Architecture Fit For The Philippines Setting

In the health sector, it is important to consider the quality of the data.  According to WHO, “Health care data are maintained for the present and future care of the patient regardless of the level at which the service is provided. The quality of that data is crucial, not only for use in patient care, but also for monitoring the performance of the health service and employees. The central theme is that data quality is proportionate to the attainment of achievable improvements in health care.”

Data quality includes:

·      accuracy and validity – of the original source data;

·      reliability – data are consistent and information generated is understandable;

·      completeness – all required data are present;

·      legibility – data are readable;

·      currency and timeliness – data are recorded at the time of observation;

·      accessibility – data are available to authorized persons when and where needed;

·      meaning or usefulness – information is pertinent and useful; and

·      confidentiality and security – both important particularly to the patient and in legal matters.

More data coming from different sources makes information management difficult. How can the health sector manage the increasing volumes of information but enable its effective processing in support of decision-making?

On the qualities of good data, I’d like to give emphasis on the accessibility, meaning or usefulness and confidentiality and security. For stakeholders, these qualities are very important (though all the qualities are equally important), I need to be able to easily retrieve (accessibility) the data and information that I need, that the data I was able to retrieve is useful for decision-making and the data in that system is confidential and secured.

In the Philippines; there are many players in the information systems.  Not only on the sources but the stakeholders that had to be considered and needs for decision-making should be met.  For the health sector in the Philippines, it is the Department of Health need not only lead in managing the increasing volumes of information and eventually being able to use it for decision making.
On an article on website forbes.com titled, Enterprise Architecture: Don't Be a Fool with a Tool, Vish Viswanathan a TOGAF expert said “ A fool with a tool is still a fool”. EA efforts are doomed to failure unless executive management becomes the champion of such initiatives.


The top four enterprise architecture frameworks compared on the article A Comparison of the Top Four Enterprise-Architecture Methodologies by Roger Session, I think that TOGAF fits best the health care situation of the our country.  The other three other frameworks could have been good but the large data for decision making is coming from different information systems. Based on the article, TOGAF rated the highest on vendor neutrality compared to the other three.


TOGAF is not wholly specific with respect to generated documents; in fact, it provides very little in the way of prescriptive document templates—merely guidelines for inputs and outputs

TOGAF can be adapted to fit any organizations initiative.  According to the Sessions, “TOGAF allows phases to be done incompletely, skipped, combined, reordered, or reshaped to fit the needs of the situation. So, it should be no surprise if two different TOGAF-certified consultants end up using two very different processes—even when working with the same organization.”

Having a framework that can conform to different situations is important because change is inevitable especially that we are dealing with technology and the political terrain of the country.

Figure 1 TOGAF Architecture Development Method (ADM)


The Architecture Continuum, shows how architectures are developed from the foundations architectures – which is composed of standards, which supports the common system architectures, The common system architechture guides the selection and integration of specific services to create an architecture useful for building solutions across a wide number of relevant domains. (eg security architechture, management architecture, network architecture, etc.) Third, the Industry Architecture guide the integration of common systems components with industry specific components and guide the creation of industry solution for targeted customer problems within a particular industry. Lastly Organization – specific architecture, it describes and guides the final deployment of solution components for a particular enterprise or extended network of connected enterprises. Which the solutions continuum concepts implements the solutions provided by the architecture continuum.

The TOGAF ADM describes the process of developing an enterprise –specific architecture and an enterprise – specific solution(s) which conform to that architecture and solutions.

The TOGAF ADM can to conform into the organization’s needs and vision.  According to Sessions, TOGAF views the world of enterprise architecture as a continuum of architectures, ranging from highly generic to highly specific. It calls this continuum the Enterprise Continuum.

In article by Sessions comparing the four frameworks through different criteria. Though, TOGAF did not rate the highest in all the criteria, it fits best for the Department of Health.  On Taxonomy Completeness, comparing TOGAF to Zachman which ranked highest, TOGAF process include a method that creates the artifacts, as to Zachman is the most complete, it is more important that the artifacts are fitting to the architecture of the enterprise itself.

The process completeness, TOGAF ranked the highest, having a step by step process is important for creating and developing an EA. Also on the information availability, having enough resources on using a framework is very important, though it ranked lowest on the maturity model, having enough resources can make up for it.  According Jason Bloomberg, TOGAF is perhaps the most popular Enterprise Architecture (EA) framework today, and its popularity is only increasing. TOGAF’s popularity, therefore, doesn’t necessarily have much to do with how well it actually helps organizations achieve success with their EA efforts. “TOGAF is not a cookbook,” explains Viswanathan. “TOGAF isn’t a cure all for all of enterprise problems. It’s merely an important link in the EA value chain.”  Explains Brown: “If people are struggling with TOGAF, either they’re not adapting it for their organization.”


The highly adaptability nature of the TOGAF is suitable for managing the large information coming from different levels of the health sector.
