• Introduction
• Aim
• Proposed hierarchical models
• Tasks hierarchy
• People’s Hierarchy
• Complete example for school activities
LAYER 0
LAYER 1
LAYER 2
Layer 0:
elementary
subtasks
Layer 1:
main
subtasks
Layer 2:
integration
Global solution

EXTERNAL VS INTERNAL REQUIREMENTS:
External (msi, msk): requirements can derive
from other main subtasks
Internal (msj): requirements can derive from
internal stimuli of component elementary
subtasks
msk

msi
HIERARCHY EVOLUTION OVER TIME:
T0: all the main subtasks are represented
T1: general deadline for execution and integration
T2: the global solution is finally reached

…
Layer 2:
final integration
EXTERNAL VS INTERNAL REQUIREMENTS:
External : coordinators of different main subtasks must be able to
communicate and cooperate properly
Internal : students working at the same main subtask must be able to
cooperate productively
HIERARCHY EVOLUTION OVER TIME:
The group of coordinators varies at each coordination step, since only one
coordinator is supposed to participate to further phases
An integrant part of each coordination step is the merging of know-how
among coordinators
Choice of hardware and software(1)
Preliminary study (2) and installation of the components inside the case:
motherboard (3), processor (4), DVD burner (5), power supply (6) graphics card
(7), network adapter (8), RAM (9), hard disk (10)
Connection of external peripherals: monitors (11), mouse (12), keyboard (13)

Preliminary study about networks and configuration of proxy/IP/DNS on the chosen
operating system (24)
Connection to network (WiFi / Ethernet) (25), configure the computer connection to the
school intranet (26), installation and configuration of all printers available on the
network (27)
Communication to the school IT manager of all parameters needed to configure the
firewall in order to allow the communication between the computer and the external
network (28), test of internet navigation (29)

Survey on which courses use the laboratories (1A), analysis of currently present
software and their rate of actual use (1B), analysis and proposal to teachers of
alternative software solutions (1C ), interviews with the students who use the lab (1D), or
to collect complaints (1E). Choose of: hardware (1F), operating system (1G), type of
connection (1H) and all the most suitable software applications (1I)
Installation of: Microsoft Office package (20A), OpenOffice (20B), GIMP for graphics
(20C), NetBeans (20D) and Eclipse (20E) for code development
Installation of: Chrome (21A), FireFox (21B) and Internet Explorer (21C)

DECISIONS TAKEN WITH THE TEACHER’S
HELP:
2nd layer: who could perform the task of
coordinating the whole project
0th layer: how many students, among the
remaining, should be assigned to each main
task
1st layer: Coordinator of each group

• Some aspects of cooperative work were
discussed
• Two hierarchies and their evolution over time
were proposed (tasks, people)
• A complete example has been shown
• Further work: stepwise refinement of both
tasks
Thank you for your kind attention
