HA NOI – 2009

Administrative activities contain many problems that need to be solved in someaspect of time schedule, responsibility and productivity The fact that building software tocontrol all problems above is better, but some software could not be used when published

In this thesis, together we will approach the problems and find why some software arefailed in real life

In this thesis, we found a new idea for the problem of administrative formalitysoftware Based on this solution, we analyzed the administrative system, built designdocument

To prove the idea, from the design document, we built the solution software toillustrate how the idea worked and prove it could help increase the software’s effect andfeasibility

First of all, I wish to express my respect and my special thank to my adviser MSc.Dao Kien Quoc, College of Technology, Vietnam National University, Hanoi for theenthusiastic guidance, warm encouragement and useful research experiences

I would like to gratefully thank all the teachers of College of Technology, VNU fortheir invaluable knowledge which they gave to me during four academic years

Last, but not least, my family is really the biggest motivation behind me My parentsand my brother always encourage my when I have stress and difficulties I would like tosend them my gratefulness and love

Chapter 1: Introduction

1.1 Introduction to administrative formalities

The purpose of administrative activities in an organization is to make decisionsprecisely to keep all parts of organization work in a harmony

Administrative activities could be able to divide into following types:

 Internal activities which involved in individual or sub-ordinates:

o Incoming document processing (register to incoming book, decidedestination, give comments …)

o Document publishing (approve document, edit document …)

o Task processing ( task requested by the manager)

o Collect documents (collect a group of document to support manager to doadministrative activities, but not create or wait for approve)

 Activities depends on external factors:

o Undetermined tasks occur when new incoming documents come ordocuments have to be sent out

As usual, activities depends on external factors contain a part of internal activities.All information and decisions are represent in document In general, both two types

of administrative activities involve in document processing, which divided into two types:

 Incoming document: from outside, via many methods: email, post office, fax …

 Outgoing document: published inside organization or sent out

1.2 Necessary of administrative activity and document processing

soft-ware

There are many reasons for a low-productive administration system:

 Lack of information or problem of finding information due to late comingdocument or a large number of documents so that people could not find

 Members’ time schedules are not synchronized: it is hard to optimize the time

deliver process or they tell lies to conceal their mistakes The only solution for thisproblem is having a way to control how officers do the task.

 The managers will find it is difficult to know the process of whole tasks unlessthey meet each individual to ask If they could not have time to arrange a meetingbetween each individual, they have to wait for the responses from subordinates.The fact that waiting for subordinates is wasting time and not effective

Therefore, we need a software that solves all problems above, which:

 Use centralization model and online processing: all documents related could bestore on server (only entity for each document), then users could access documentseverywhere Moreover, users could search for document without any difficulties

 Tasks will be uploaded directly: saving time of all members Users have to accessthe Internet to view tasks Result will be sent to server and could be viewed everytime and everywhere That solution could increase the productivity

 Distance will not be a problem anymore User could view activities at any place

 Individual’s responsibility will increase because all task and status of task(finished, not completed …) is public Moreover, log files to mark all states oftasks will be the evidents to control subordinates

 Task reminder is run automatically to remind so that users could not forget thetask

 All documents will be verified by electric signatures to ensure the reliability andindividual’s responsibility

1.3 Determine why some software failed to be used when published

Not only solving problems mentioned above, the software has to satisfy some factors

to become successful:

 The technology used: it decides the effect of the software including powerful, fast,etc or the compatibility with other softwares or browsers

 The cost of the software: the cheaper software is better

 Graphic interface: the graphic interface decides the easy-to-use aspect of software

However, many software which satisfy all factors above have failed in real life Onereason that all softwares built for administrative activity purposes could not used in real

life is “users find it difficult to use them”.

Traditional method problem: Traditional method is a group of steps that officers

have been using for several years such as deliver the paper documents, sign the documentusing pen … which almost involve in paper documents At middle age, people tend toprefer to work the same as they have worked for years so trying a new method like usingcomputer is hard for them Moreover, at these age, people could not learn as fast asyounger ones Therefore, they think it is better if they use traditional method again instead

of using computers

As usual, all software when published require a period of time to train users, but mostusers who use administrative formalities software are middle-age people who do not havemuch experience in using computer, especially in Vietnam They get troubles in someissue:

 How to locate the document in computer when downloaded successfully

 How to find a document in a folder full of downloaded documents

 How to upload files to server

The reason is the steps they have to do with the software are much different from

steps they usually do in real life, which is considered as traditional method

That is the reason why some software is published but never used

1.4 Solution

Idea of automatic steps:

As mentioned in previous section, some steps that users may find difficulties indownloading, opening and uploading files My idea is the software has to automatically

do these steps for users: all steps that much different from traditional method should be

The advantage of this idea is the users do not have to care about what is happeningunder these steps, they simply do the steps which familiar to them Therefore, it bring twosequential advantages:

 Users may find using software is more convenient than using traditional methodincluding saving time deliver the document or waiting for responses, being able towork at any place …

 Saving time and money to train users how to use the software: if it is nearly thesame with traditional method, users do not have to learn much

The specific of this idea is mention in Chapter 4 Section 4.1

Idea of using ePad device to sign and write comments:

ePad is a device which allow users to write directly to the document with its ownsignature verification method After opening the document automatically by software, themanager does not has to write to a text area to sign or give comments, he simply sign as

he usually do with paper document

The advantage of this idea is it is definitely the same as traditional method, whichworks with paper document:

 The manager does not have to learn how to use text area, how to send signature …

he simply open the document and sign using pen attached with ePad device

 The signature verification method of ePad helps users rely on the authentication ofthe person who signed

The more specific approach of ePad device is mention in Chapter 4 Section 4.2

Chapter 2: Requirement and Specification

2.1 Problem analysis:

Document processing in administrative system is divided into four categories:

2.1.1 New incoming documents processing:

New incoming documents processing is divided to following steps:

 After receiving new incoming documents, administration department registersthis document into “incoming book”

 New documents will be sent to the manager to check

 New incoming documents will be stored by administration department

 Publish of new incoming documents depends on the right level of staffmember, which decided by the manager

 The destination of the documents after reviewing depends on the manager (themanager will note on the document to which department the documents belongto)

 The employees could see the document based on their own right level

2.1.2 New outgoing document processing:

New outgoing document processing is divided into following steps:

 The officer or manager who desires to create new document will have to createnew document first

 After being completed, the document will be transferred to collect commentsfrom other departments

 After receiving comments, the author could edit the document beforeforwarding to administration department

 The administration department will check as if the document satisfied all

o if it pass all requirements, it will be sent to the manager

 The manager who receives the document will approve the document

 If the document is approved, it will be stored and registered into “outgoingbook” by the administration department

 The document will be set the right of reading before publishing or distributing

by the manager

 The destination written in the “outgoing book” will be the address of thecompany or organization if the document has to be sent out, but the destinationcould be noted as “internal publishing”

2.1.3 Task processing:

Task processing includes following steps:

 When a chief or a manager need to assign tasks, he has to determine therequests, due date and has to attach related documents if necessary

 The chief or the manager also has to divide the task into steps with conditions,order and due date for each step

 Then he has to specify who is responsible for each step and who is responsiblefor the whole steps

 The subordinates who read the task could comment or provide solutions for thetask

 An individual or group of people who is responsible for the task could attachproduced documents

 The individual or the group will be reminded when the due date comes

 The individual has to confirm the state of the request or the task

 The individual could also request to get responses from the person whorequested or notice the following task of the request to another

 He could attach produced documents if necessary with the request or taskprovided

2.1.4 Task schedule:

Each individual has to be provided a schedule which contains the tasks of a period

of time ( such as a week, a month, a quarter … ) with the due date and priority to work in

a harmony with other people

2.2 Requirement and solution

2.2.1 Requirement

Document processing and administrative formalities involving occurs in everycompany, organization … with years of traditional method The purpose of a documentand administrative formalities system based on Internet is reduce all unnecessary stepsincluding steps which take much time like sending documents from department todepartment or steps which are complicated like dividing tasks for a group of people

Each company or organization has its own unique aspect in processing documentand administrative formalities, but all of them contain following issues:

 New incoming documents processing: new documents from other organization

include many tasks from registering into books to performing content ofdocuments

 New outgoing documents processing: new outgoing documents in order to be

released are required to follow many steps: from checking draft documents tosending to manager to publishing or sending out

 Task processing: the requirement of tasks occurs based on documents is how the

manager could keep all tasks worked in a harmonic and finished earlier thandeadline In addition, the manager has to find a way to control responsibilities ofsubordinates

 Task schedule: the fact that hundreds of task given every day suggests each

person have a schedule to remind next tasks and to arrange time logically

The purpose of the system is to change all four issues of processing documents and

2.2.2 Solution

a Using server – client model to work with documents and tasks

Four main functions need to be built:

New incoming document processing: The information “incoming book” will be

stored in database Documents will be stored in server so that everyone could view thedocuments (actually there is an only document for each incoming document stored inserver and everyone explores it) The manager could decide the destination of thedocument directly instead of communicating with administration department Theemployee could connect to the Internet to view and download the documents if possible

New outgoing document processing: Document created is stored in database and

could be viewed directly by specific person without taking time to print and to transfer tospecific department The administration department could check it and send back throughInternet to author The manager could set who could see the document Information of

“outgoing book” is stored in database The employee could view and downloaddocuments when connecting to the Internet Other organizations will receive documentsvia email

Task processing: The manager could create a task then divide it into sub-tasks Each

task or sub-task could be inserted due date and who is responsible and status (finished, notstarted, being done), edited and deleted People could view their given tasks, givecomment and suggestion for the tasks They could also send messages to others and getresponses about document’s issue If due date comes, people could be reminded bysystem The manager could view all tasks status to control all processes and could remindsubordinates if necessary

Task schedule: Each person has his own schedule to look up and could view due date

of all tasks

b Support all functions using Internet services

When joining the company or organization, each person is provided an account tologin to system With this account, a person could execute all functions above, butfunction’s activities depends on type of user and right of user in each specific situation

c The development based on human – like activities

People’s feeling about the system in aspect of easy to use, productive or not depends

on how the activities of system relate to real life especially how they relate to traditionalmethod With this idea, a successful system is the system requiring less time to learn, lesssteps of mouse click or less fields to type Therefore, the system need to reduce steps ofoperation, moreover, some steps like viewing document, giving comments could beautomatic: the document should be automatically downloaded and open, the commentsshould be attached directly to the document if necessary, etc
