Sistemin ömür devri,
bir fikir ile başlar,
paydaş ihtiyaçlarının sistem mühendisleri tarafından
tanımlanması ile sürer,
tasarım, entegrasyon ve kalifikasyon ile devam eder,
üretim, kullanım ve iyileştirme aşamalarından geçer.
Sonunda sistemin emekliye ayrılması ve imhası ile
tamamlanır.

Systems Engineering Management Plan
A Systems Engineering Management Plan (SEMP) is used to establish the technical content of the engineering work.
The SEMP is written early in the formulation phase for each project and updated throughout the project life cycle.
The SEMP provides the communication bridge between the project management team and the technical implementation teams.
The SEMP provides the specifics of the technical effort : what technical processes will be used
how the processes will be applied using appropriate activities
how the project will be organized to accomplish the activities
what appropriate work products will be produced
the cost and schedule associated with accomplishing the activities.

ÖMER ERTEKİN, PSCONSULTECH
SEMP Kapsamı
• Proje Kapsamı
• Proje Mühendislik Yönetimi ve Program Yönetimi ile İlişkisi
• Sistem Mühendisliği Yönetimi
• Sistem Mühendisliği Analiz ve Tasarım Süreçleri
• Alan Uzmanlığı Entegrasyonu
• Özel Mühendislik Alanları
• Sistem Mühendisliği Riskleri

The SOW is:
The highest level capture of the activities to be performed
Narrative description of the work required for a given project
Developed from the overall project SOW in the PMP
Read by engineers as well as accountants, contract managers,
schedulers, lawyers, etc. (must be no ambiguity)
Basis for definition and costing of detailed tasks
Basis for subcontractor and supplier requirements
İŞ TANIM DOKÜMANI (SOW)
Mayıs 2012, Ders 9 Sürüm1 10
ÖMER ERTEKİN, PSCONSULTECH
The SOW includes:
Summary statement of tasks to be accomplished
Identification of input requirements from other tasks
References to applicable specifications, standards, etc.
Description of specific results to be achieved and
deliverables
İŞ TANIM DOKÜMANI (SOW)
Mayıs 2012, Ders 9 Sürüm1 11
ÖMER ERTEKİN, PSCONSULTECH
General guidelines for preparing a SOW
Short, to the point, 2-3 pages, clear and precise
Avoid ambiguity and possibility of misinterpretation
Describe requirements in sufficient detail to ensure clarity
Must consider practical applications and possible legal
interpretations
Do not underspecify or overspecify
Avoid unnecessary repetition and extraneous material and
requirements
Do not repeat details already in applicable referenced
documentation
İŞ TANIM DOKÜMANI (SOW)
Mayıs 2012, Ders 9 Sürüm1 12
ÖMER ERTEKİN, PSCONSULTECH
Follows SOW generation
Product-oriented family tree that leads to
identification of activities, functions, tasks,
subtasks, work packages, etc., that must be
performed for the completion of a given
program
Is not an organization chart for personnel

WBS
Mayıs 2012, Ders 9 Sürüm1 13
ÖMER ERTEKİN, PSCONSULTECH
Project activities
Functions
Tasks
Subtasks
Is a representation of organization of work
packages
The purpose of the WBS is to be a framework for:
Considering the products, services, and
information need to fulfill objectives and
scope of the project (MM)
Project planning and control
Program planning, budgeting, contracting, and
reporting
WBS
Mayıs 2012, Ders 9 Sürüm1 14
ÖMER ERTEKİN, PSCONSULTECH
List task breakdown in successively finer levels of
detail
Continue until all meaningful tasks or work packages
identified and each task can be individually planned,
budgeted, scheduled, monitored, and controlled
Test for completeness: If you are detailing the process for
doing or producing something in the WBS, you have gone
one step too far
Branches need not be the same length, number of levels
driven by complexity of that portion of project
WBS
Mayıs 2012, Ders 9 Sürüm1 15
ÖMER ERTEKİN, PSCONSULTECH
Total system easily described through logical breakout of its elements into nicely definable work packages
Increases probability that every program activity will be accounted for
Links program objectives and activities with available resources
Facilitates the initial allocation of budgets and the subsequent collection and reporting of costs
Provides excellent matrix for assignment of tasks and work packages to various organizational components, responsibility for assignments can be readily identified
Vehicle for reporting of system technical performance measures (TPMs) against schedule and cost

The Even Planning Process: A hierarchical planning framework
Steps
Level 1: Make a list of major activities in general order of occurrence (about 2 to 20 activities)
Level 2: Breakdown each Level 1 activity into 2 to 20 tasks
Level 3: Breakdown each Level 2 task into 2 to 20 subtasks
Continue until tasks at each level are “manageable”
Fundamental: Be sure all tasks at a specific level are at the same level of detail (or level of generality)
Project manager usually performs Level 1 and delegates lower levels to those who will do work
Objectives are from project master plan
