Prospek Bisnis IT Saat ini di Indonesia
Memulai Bisnis IT
Mulai dari Hobby Lihat sumber daya yang dimiliki Inkubator, small office dll. Tentukan Goal setting Urus ijin legalitasnya Jualan, produksi,implementasi dan
sosialisasi
Mulai dari Hobby: Sejak kecil mprogram
Hobby nguprex hardware
Hobby mengambar dan seni
Atau hobbynya jualan
Resource SDM: ( Engineer:Ahli Jarkom,Sistem analisis, programmer,
teknisi, marketer, manajer etc) Modal Usaha:
Small office software House: 3-5 engineer Investasi :3-5 PC= Rp.9 jt s/d 15 jt Biaya operasional: rp. 6 jt-10 jt perbulan (bagi hasil) Target: project :borongan, tanpa tender, siap di broker
Medium office software House: 10-15, 15-20 engineer Investasi :10-15 PC= Rp.30 jt s/d 45 jt Biaya operasional: rp. 20 jt-30 jt perbulan (bagi hasil) Target: project :borongan, tanpa tender, tender terbatas,siap di broker
High office software House: >20 engineer Investasi banyak investor Biaya operasional: diatas 1 M Target: project :Tender tak terbatas, memiliki R&D cukup tinggi
Berapa banyak relasi:Pemerintah, vendor IT, Swasta dll.
Why do so many projects fail?
Reasons in many cases Very few managers know project management. Very few engineers know software engineering.
When will the project finish?
So many claims.What happens?
Over the budget.cut engineers
Feature is behindthe competitor
Chaos
Tentukan Goal Setting
Project Management Strategy 5 Steps to improve project management
Management Documentation, Mile-stone control, Software Metrics
Quality Test Theory, Design Review,Problem solving method
Productivity Development Environment,Reusability
Value Added High Reliability/Performance,User-Friendly Interface
Chaos Difficult to forecast the scheduleand the quality
Order of Actions is important Without management platform, you cannot evaluate the quality. You can’t ship the system under quality. If you pursue the productivity before quality, then the project goes worse.

Stage
Name of stage, output may differ according to the system/organization.
Step by Step Development
Design Stage Design Activities
To read upper documents and list up study issues To investigate the study issues To write down Specification/Design Documents To review the documents
Viewpoints of Project Management Design Sheet
Summary paper on investigation of a study issue The background or reason of technical judgment is to be kept 、 because the
specification often tells us nothing about it Design Review
Review is the cheapest way to detect a bug, and the best way to understand the system
Interim Inspection Check of the design output by the inspection division We cannot proceed to the next stage without passing it
Gant Chart
Task Main activity of each stage Task is followed by its progress and quality metrics
Work Subsidiary activity of each stage Work is measured not by progress, but only by its completion

How to solve the problems
Viewpoints of Project Management To check the properness of selected Test Cases Even if a project is small, all problems are to be
recordedOne error indicates other similar errors in it.Be careful about an unintentional miss-operation.
One error indicates other similar errors in it.
A Problem once happened surely happens again.
Be careful about an unintentional miss-operation.
One error indicates other similar errors in it.
When a problem happens?
Human beings are those who makes a mistakes.
A Problem once happened surely happens again.
Be careful about an unintentional miss-operation.
One error indicates other similar errors in it.

Suggestions for High Quality
Tabular/Graphical Documentation is the better wayto define the specification with the less errors
To write down a document often makes usfind a problem and straighten our understanding
Circulation of information/notice and good communication help us to avoid a problem.
