If we want to collect information as evidence to support our decisions there are following aspects we should consider and take into account at least these three issues:

•  Method(s) to collect data and information and triangulation

•  Quality of data and information: relevance, reliability and accessibility

The method: The method means procedure how is something done. In our case of gathering information it is mainly about processes and tools of obtaining data (facts) and information. 

Generally we have two main sources of data:

i.         Secondary data obtained thought desk research

ii.   Primary data obtained thought own field research

For more detail see the next chapter where we discuss the methods that could be used during the research phase in detail.

The data and information should have desired quality to be able to support our decisions. In Module 1 we have discussed the following dimensions of quality that the data and information should have:

• Relevance

• Reliability and completeness

• Validity (accuracy)

• Accessibility

For more detail see the Module 1 Reliable source of information.

When designing our own research we should, regarding the quality of data, take into account primary the following:

• The research should concentrate to collect relevant data that suit purposes and goals of the research.

• The data concerning the issue should give us complete picture. Data cannot be ever fully complete (meaning that we will have all the data concerning the issue – that would be the reality itself). But we should cover  all the key aspect of the issue concerned.

-        relevant research questions have to be asked

• When using the secondary data sources we should make sure that the data are reliable.

-        source of data is reliable

-        data are valid (accurate)

• We also have to consider our time and resources available to ensure accessibility of the data (for us)

For more detail about the quality criteria for data see Module 1 Reliable source of information.
