Personal Assignment 4 Session 8 1. On June 12, 2011, GPU Corporation was awarded a $160,000 contract for testing a product. The contract consisted of $ 143,000 for labor and material, and the remaining $ 17,000 was profit. The contract had a scheduled start date of July 3. The network logic, as defined by the project manager and approved by the customer, consisted of the following: Activity Time (Weeks) AB 7 AC 10 AD 8 BC 4 BE 2 CF 3 DF 5 EF 2 FG 1 On August 27, 2011, the executive steering committee received the following report indicating the status of the project at the end of the eighth week : Activity

The steering committee could not identify the real status of the project from this brief resport. Even after comparing this brief status report with the project planning budget as follow, the real status was not readily apparent : Activity 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 AB 2K 2K 3K 3K 4K 4K 3K AC 3K 3K 3K 4K 4K 4K 4K 2K 2K 1K AD 5K 5K 6K 4K 4K 4K 3K 1K BC 3k 4K 4K 5K BE 6K 6K CF 2k 3K 3K DF 3K 3K 3K 4K 4K EF 2K 2K FG 3K Assumes that percent is linear with time and nonlinear with cost

Management instructed the project manager to prepare a better status report that depicted the true status of the project, as well as the amount of profit that could be expected at project completion. Your assignment is to prepare a table such as below : Project Costs 1 2 Activity Percent Complete

Total Cost Variance ($) = Column (4) – Column (5) = ..................... Schedule Variance ($) = Column (4) – Column (3) = .................... Cost at Completion = rate spending x Total Budget = (Column 5 / Column 4) x ( )= ................... Cost to Complete = Cost at Completion – Actual Cost = .......................

2. Salah satu metode untuk menghitung biaya proyek perangkat lunak adalah model COCOMO. Biaya yang dihitung berdasarkan jumlah baris kode program (dalam KLOC, yaitu Kilo Lines Of Code). Jenis perangkat lunak yang dikembangkan dapat berupa"console" (misalnya aplikasi yang berjalan dalam MS-DOS), "GUI-based" (misalnya aplikasi windows), atau "real-time" (misalnya perangkat lunak pengendalian kendaraan bermotor). (bobot 25%) Dari pengalaman masa lalu rumus COCOMO yang digunakan adalah: Console systems:

PM = 2.4 * (KLOC)1.05

GUI-bases systems:

PM = 3.0 * (KLOC)1.12

Real-time systems:

PM = 3.6 * (KLOC)1.20

Berdasarkan hasil analisis system yang akan dikembangkan dengan berbasiskan window GUI diperoleh perkiraan jumlah baris kode program sebesar 75.000 LOC. Jika diasumsikan biaya pegawai tiap bulan (PM) sebagai berikut: System Analyst

$10.000 /PM ("analyze requirements")

Programmer

$6.000 /PM

("design product", "programming")

Tester

$9.000 /PM

("plan tests", "verification/validation")

Manager

$12.000 /PM ("project Management")

Support-Team $7.000 /PM

("CM", "QA")
