Backround
- Geostat 1A,1B and 1C projects (2010-2014)– Creation of national population 1 km² grid data sets – Harmonisation of
• The grid net• Population data by 1 km² grids
– First attempts to describe the production process
- Geostat 2 (2/2015) ->- Premilinary ”Framework for Spatial Statistics”
• GSBPM – Generic Statistical Business Process Model (5.0)

GSBPM Generic Statistical Business Process Model
11 November 2015
- The GSBPM describes and defines the set of business processes needed to produce official statistics.
- It provides a standard framework and harmonised terminology to help statistical organisations to modernise their statistical production processes, as well as to share methods and components.
Level 1
Level 2

Processes of spatial statistics have also been described earlier …
- Phases were identified independently – the GSBPM was not used
- Interpretation of the process flow diagram is difficult – a certain level of abstraction would be needed
- BPMN (Business Process Model Notification) was not used
- The value of the work was to identify tools and instructions needed during the process

Objectives of Geostat 2 - and SF tasks
Geostat 2, Work Package 1:
Model for a point based administrative geospatial reference framework
Stat FI: - Aims to create a national model
– Define a role of spatial data in the statistical production process and using GSBPM describe a general process, alsodefine connections to other supportive systems (such as metadata, classifications, quality descriptions)
– Test the model: INSPIRE data product (demography)- The model will be evaluated by others (AT, PT at first)
Rina Tammisto8
First questions and findings
- What are the targeted processes?– Recognition of the key processes
• Relate to spatial statistics• Relate to map data
- What is the ultimate outcome we aim at?– A preliminary model was illustrated
- What should be the level of process descriptions in order to achieve a general model ?

Premilinary ”Framework for Spatial Statistics”
11 November 2015
- To introduce to the GSBPM- To identify key processes
- Inspired us to continue the work
- Good feedback !!

Modeling of processes – target processes
- To start - perspective (traditional Geostat topic): Inspire, Demography - Population distribution
- Identification of two processes:– Production of “Grid Net for statistics (1 km x 1 km)”– Production of “Spatial Statistics”– Production of statistical units (not yet, but most likely needed)

Modeling of processes Story Mapping method: http://www.slideshare.net/SteveRogalsky/user-story-mapping-in-practice
1. Writing down free cognitive associations (tasks) of the process
2. Classification of notes and identification of phases + completion by phases still missing
3. Identification of GSBPM phases + completion by phases still missing
4. Creation of the model + recognising actors

CREATING A PROCESS MODEL
MS Visio: BPMN Business Process Model Notification

Experiences- The level of abstraction that is essential for understanding the
process must be chosen (as high as possible)– Helps identify similarities between processes
- The process itself and the supportive sub-processes have to be distinguished
- After finding the right GSBPM phases some missing phases could be detected
- Some GSBPM phases must be repeated during the process Acceptable from the point of view of GSBPM instructions
e.g. In process phase 5 - 5.1-5.8• Actions in order to produce statistical data • Actions for combining statistical data with spatial boundary data

Rina Tammisto14
Experiences
- Process phases are quite easy to fit to the GSBPM model!– The GSBPM model descriptions do not contain any
description or reference to spatial data - A GSBPM pro is therefore needed
- Use of GSBPM requires raising the level of abstraction when interpreting phases – Suggestion: could the abstraction level be higher already
in phase descriptions of GSBPM?- A big surprise: the method is very fast!

Lessons learned: GSBPM ”rules of use”
11 November 2015
1) Modelling itself is not the target – to understand the process is
2) Describe the process as it is – after selecting the level of
granularity
3) Apply the model – use it as a tool

Follow-up
Production process of spatial statistics in SF– A synthesis
A point based administrative geospatial reference Framework is the main goal- The process model stands as a base
– Identify connections to other systems (such as metadata of data and processes, classifications etc.)
– Identify the actors (stakeholders involved)– Test the process for production with an INSPIRE compatible
data product (Demography)- The model will be evaluated by others (AT, PT at first)
