ISMA 2012 Presentation Slides

1

• Documentation of information systems; • Legacy systems in operation for a long

time without proper or up-to-date documentation;

• Capturing screens, processing sequence; understanding the logic and generating inputs for counting;

• Attention points that would facilitate the counting process;

• Increasing productivity during the counting process.

Key concepts

2

Objectives

• How the documentation of the most legacy systems in operation for more than two years in Brazil are presented today;

• How Abrantes Soluções has handled the services of function point counting for these systems;

• How to get inputs for counting; • How to document these inputs; • What is the increase of productivity of the counts

obtained using this method;

• 80 Function Point for one day of work, for one professional:

Legacy Systems;

More than once we were caught in this trap;

But were was the bottleneck?

How to keep our average/regular counting performance in those occasions?

9

The Solution

To answer these questions, we tried a new method of

work, that we are about to introduce here.

10

The Solution

It isn’t a “magic solution”, not even a complicated

process, full of numerous sophisticated variables. Does

not require any special tool.

11

The Solution Simple Solution

Accesible to any user in International Function Point;

Equally effective; Allows to perform with some accuracy the Function

Point counting in a legacy system that does not have a complete documentation.

Steps of counting point function according to CPM 4.3.1

13

• Consists in searching the understanding and knowledge of the system and its functions from “navigation” or “demonstration”; • Holistic approach – complete

system; • Create evidences for each system

process / function; • Enables counting and audit

validation afterwards.

The Method

14

The Method

Seeking Inputs

Check software’s references

Schedule software’s

presentation

Get elements from inputs (screens and important information)

Review and format inputs

Aprove Inputs

Documentation Deliver input

documentation for counting

15

The Method

Seeking Inputs

Checking references of software

• Responsibles / Users / Managers (Who knows?);

• Data models (conceptual or logic); • System manuals, user guides(even if

documentation is outdated); • Other documents (if exists).

16

The Method

Seeking Inputs Schedule presentation of software

• Responsibles; • Users; • Bussiness Officers/ Managers.

It can be necessary to schedule multiple appointments.

17

The Method

Seeking Inputs Get elements of documentation inputs

• Identify the scene; • Identify functions available to users; • Capture/Print Screenshots; • Record relevant information; • Record source / destination of

information.

18

The Method

Seeking Inputs Get elements of documentation inputs

• It’s common the manager who wants to:

• Create a counting worksheet;

• Start the counting by filling the

worksheet.

19

The Method Seeking Inputs

Revise and format input documentation

• Standardize according to the project; • Each company is different; • Check if everything that was presented

got documented; • Document your general view about the

system; • Document the points of attention’s for the

counting; • Formalize the common understanding

between you and the person presenting the system 20

The Method

Seeking Inputs Aprove input documentation

• Check if everything that was recorded is clear;

• Document your impressions about the system;

• Document the points of Attention about the

system;

• Aprove input documentation.

21

The Method

Seeking Inputs Deliver input documentation

• Deliver the input’s documentation for

counting FP;

• Request feedback about the

documentation;

• Record lessons learned. 22
